Why Choose the GR Supra Valved Exhaust for Your Toyota A90/A91

The Toyota GR Supra A90 / A91 is one of the most dynamic platforms in the modern performance world—tight, responsive, and powered by the BMW-sourced B58 and B48 engines. But while the chassis and powertrain are born to perform, the factory exhaust leaves enthusiasts craving more emotion, more aggression, and more control. That’s why Yonristic Performance developed our Valved Sport Exhaust System specifically for both the 2.0L B48 and 3.0L B58 Supra platforms.

Whether you're piloting the lightweight, nimble 2.0L or the straight-six turbocharged beast, this exhaust brings your Supra to life with a commanding presence and exotic tone—without sacrificing comfort.

Built around a full 3.5-inch mandrel-bent mainline, the system splits into a precision Y-pipe configuration with dual 2.75-inch outlets, optimizing both flow and pressure distribution. The layout is designed to reduce turbo lag, increase mid-range response, and amplify the car’s natural tone—whether you're at idle or full throttle.

At the rear, electronic valve control allows you to toggle between two personalities: refined and composed with the valves closed, or raw and aggressive with the valves open. Paired with Yonristic’s signature 4-inch tips, available in polished, black, or burnt finishes, the look is just as bold as the sound.

Crafted from TIG-welded 304 stainless steel, this system ensures perfect fitment, long-term durability, and a show-quality finish. The entire system is bolt-on, emissions-safe, and integrates with both OEM and aftermarket diffusers and valance designs.

Key Features:
✔️ Full 3.0-inch mandrel-bent mainline – smooth, unrestricted flow from front to rear
✔️ Y-pipe dual 2.75-inch exits – balanced pressure and enhanced exhaust character
✔️ Supports both B58 (3.0L) and B48 (2.0L) engine variants
✔️ Electronically controlled valved mufflers – switch between stealth and sport on demand
✔️ TIG-welded 304 stainless steel – engineered to perform and built to last
✔️ Signature 4-inch tips – available in polished, black, or burnt finishes
✔️ Bolt-on installation – no tuning, no cutting, no CEL
✔️ Fully compatible with factory heat shields and OEM mounts

Vehicle Fitment:

  • Toyota GR Supra A90 / A91 (2020–2024)

Two Engines. One Perfect Sound.

Whether you own the 2.0 or 3.0 Supra, Yonristic Performance gives you the power to control your sound—refined when you want it, explosive when you don’t.

This is the exhaust system your A90/A91 Supra was meant to have.

Let the world hear your boost.

 

Engineered for Controlled Performance

The GR Supra Valved Exhaust is built for drivers who want a sharper exhaust note without sacrificing daily comfort. Designed for the Toyota A90 and A91 GR Supra, this performance system uses valved technology to give you control over sound output when you need it most. Keep the valves closed for a quieter ride in traffic, then open them for a more aggressive tone during spirited driving. This flexible setup makes the exhaust ideal for both street use and track-style performance, giving your Supra a more exciting driving experience while maintaining a refined level of control.

Premium Fitment and Stronger Exhaust Flow

Made specifically for the A90 and A91 chassis, this system offers a precise fit that supports clean installation and dependable long-term use. The design helps reduce exhaust restriction, allowing spent gases to exit more efficiently and supporting improved engine response. With smoother flow and a more direct path, the exhaust can help your Supra feel more lively and responsive under acceleration. Built with performance-focused construction, it is made to handle demanding driving conditions while enhancing the overall character of the car. It is a smart upgrade for owners who want quality fitment and noticeable performance appeal.

A Deep, Aggressive Sound That Stands Out

One of the biggest reasons enthusiasts choose a GR Supra Valved Exhaust is the sound. This system delivers a deeper, richer tone that matches the sporty personality of the Supra without becoming overly harsh. When the valves are open, the exhaust produces a stronger and more exciting note that turns heads and adds presence on the road. When closed, it stays more manageable for everyday use. That balance makes it especially valuable for owners who want both comfort and excitement in one package. It is a refined sound upgrade that brings out the best in the Toyota GR Supra platform.

Built for Enthusiasts Who Want More Control

For Supra owners who care about driving feel, sound, and style, this valved exhaust system delivers a well-rounded upgrade. It gives you the freedom to match your exhaust tone to the moment, whether you are commuting, cruising, or enjoying open-road driving. The system supports a more engaging connection between driver and machine, while also adding a premium performance look beneath the car. Yonristic has designed this exhaust to meet the expectations of enthusiasts who want more than a simple replacement part. It is a true performance-focused enhancement that helps your Toyota A90 or A91 GR Supra stand out with confidence.

FAQs

Will this require a tune after installation?

Bolt-ons like exhaust tips, cat-backs, and basic intakes usually don't. Larger mods — turbo upgrades, supercharger kits, headers — typically need an ECU tune to run safely. The spec sheet indicates if tuning is recommended.

Is this part emissions / CARB compliant?

If you're in California or another CARB-regulated state, check the CARB status on this page before ordering. Many performance parts are off-road or competition use only — if so, we say it clearly.

Will installing this void my factory warranty?

Modifications can affect manufacturer warranty on related components only — not your entire warranty. The Magnuson-Moss Warranty Act protects you from blanket warranty voids. If warranty matters to you, talk to your dealer before installing.

Can I install this myself?

Depends on the part. Bolt-ons are DIY-friendly. Turbo upgrades, headers, and supercharger kits need a professional shop. The product description gives a difficulty estimate.

Frequently Asked Questions

How do I know this will actually fit my car?

Every part listing shows compatible years, models, and trims. But here's the thing—trim packages and factory options can be confusing. If you're not 100% certain, text us at 772-277-2495 with your VIN or photos of your car. We'll verify fitment before you order so you're not stuck with an $800 part that doesn't fit. We've done this for 30,000+ builds. We've seen every weird trim combo and factory option. Takes us 2 minutes to verify, saves you weeks of headaches.

What if the part arrives damaged or is the wrong item?

We handle it. You don't fight with freight companies or file claims. Text us photos within 48 hours of delivery. If it's damaged or wrong, we ship a replacement immediately. You're not waiting 6 weeks for a freight claim to process. We eat the cost, not you. This is why we package everything like it's going to war. But if something slips through, we fix it ASAP. No forms, no back-and-forth, no "file a claim and wait." Just text us and we handle it.

Can I install this myself or do I need a shop?

Depends on the part. Emblems, front lips, some spoilers, bolt-on, DIY-friendly, you can do it in your driveway with basic tools. Full bumpers, hoods, wide-body kits, possible for experienced DIYers but most people take them to a shop for paint and install. Check the product description for installation difficulty. If you're unsure, text us. We'll be honest about whether you can handle it or if you should take it to a pro. We'd rather you know upfront than get frustrated halfway through.

What's your return policy if it doesn't fit or I don't like it?

30 days, unused parts in original packaging. You pay return shipping unless we sent the wrong part or it arrived defective. Once you install it, modify it, paint it, or mount it, we can't take it back. That's why we push so hard on verifying fitment BEFORE you order. We don't want you stuck with something you can't use. Text us before ordering if you're unsure. We'll confirm fitment so you never have to worry about returns.

Do you offer financing?

Yes. Affirm and Shop Pay available at checkout for orders over $50. Split payments over 3-12 months depending on order size. No hard credit check to see your options. Most people use this for big-ticket items like body kits, suspension setups, or wheel/tire packages. Rates vary based on credit. You see the monthly payment before you commit. Makes it easier to build now instead of waiting months to save up.

What if I have questions after I receive the part?

Text 772-277-2495. We don't disappear after you buy. Fitment questions, installation issues, "does this bolt go here" questions... we'll walk you through it. We've installed these parts ourselves or helped hundreds of people install them. You're not getting transferred to a call center in the Philippines. You're texting someone who's actually installed your part before. If we can't help remotely, we'll recommend a local shop that knows these parts.

Why should I buy from K2 instead of eBay/Amazon/other sites?

eBay and Amazon sellers don't answer fitment questions. They don't verify your VIN before shipping. They don't handle freight damage claims for you. If something goes wrong, you're filing disputes and waiting weeks. We're builders selling to builders. We verify fitment before you order. We handle damage claims same-day. We answer texts in minutes. We're not the cheapest, but you're not gambling $800 on whether a part fits. You're paying for support, verification, and someone who cares if your build goes sideways.

What does your warranty cover?

1 year against manufacturing defects: cracking, warping, paint peeling, hardware failure, fitment issues caused by the part being made wrong. Does NOT cover installation damage (you cracked it bolting it on), road damage (curb rash, rock chips), or normal wear. If it breaks because we made it wrong, we replace it free. If it breaks because you hit a parking block, that's on you. We're fair about it. Send photos and we'll tell you honestly if it's covered.

Shipping

Do you ship overseas?

Yes, we ship all over the world. Shipping costs will apply, and will be added at checkout. We run discounts and promotions all year, so stay tuned for exclusive deals.

How much does shipping cost and when will I see the total?

Depending on where you're located, small parts can ship free. Large parts like bumpers, hoods, and body kits require freight shipping. Uou'll see the exact cost at checkout before you pay. Freight usually runs $150-$300 depending on size and your location. We know it's expensive. We negotiate the best rates we can. If you're ordering multiple large parts, text us. We can sometimes combine shipping and save you money. We're not hiding fees in the final step. What you see at checkout is what you pay.

How long will it take to receive my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.

Customer photo review of NTXGlow RGB Tail Lights (2015-2023 Ford Mustang)

Took 2 weeks to deliver with standard shipping. But well worth the wait. Install took 25 minutes with minimal tools and the lights look amazing. Fitment is perfect and the quality is excellent. Its kinda pricey but you get what you pay for with ntxglow products. Highly recommend!

Customer photo review of Spec-D Projector Headlights Ford F150 (04-08) Mark LT (06-08) Halo Black / Smoked / Chrome

They look amazing, and after using ChatGPT to help me understand how to install them (because the instructions were not very helpful whatsoever), I’m glad with how they turned out. My problems are that the lights aren’t too bright, the instructions weren’t helpful, and the arrival date was wrong, even if they arrived early.

Customer photo review of 1993-1997 Honda Del Sol Redclear Tail Light Lenses

This isn’t on K2, but the lenses came In which I was thrilled about. I’d already removed my OEM lenses from their housings. The passenger side lense fit well and mostly flush. The driver side, however, looks like it was slightly warped and caused poor fitment and what looks like a small dip in the red portion of the lense. I had no choice but to use them, as my OEM lenses were no longer usable. It can be very difficult to get replacement lenses in a timely manner for a Del Sol. I drive my car everyday, so I had to just go with it. Again, not a K2 issue but presumably the manufacturer.

Customer video review of 2003-2008 Nissan 350Z N4 Style Rear Bumper Cover - FRP

This rear bumper fits great the only thing is the trunk button on the bottom is cut a little to wide but that’s an easy fix it looks great and definitely makes the rear look more aggressive. I love it!

Customer photo review of Upgraded VANOS Oil Supply Line – M52 / M54 Engines (E36, E46, E39, E60, X3, X5, Z3, Z4)

The box was a little crushed, but the line was packed well and it wasn't a problem. The instructions are 3 pages of color pictures and lots of explanations. Very nice. The line itself is a very nice bit of kit with a swivel AN line end that allows a No-tension install. No leaks so far and it looks great. It came with new banjo bolts and copper crush washers. The only criticism I have is that I would have liked this hose coated in black so it disappears like the original, but it does look good, so I don't mind.
