It depends on your goal. A catback exhaust replaces the system behind the catalytic converters and mainly changes sound and weight, and we carry GR Supra catbacks and axle backs from AWE, Akrapovic, Milltek, Borla, MagnaFlow, Invidia, HKS, Dinan, aFe, Injen, MBRP, REMARK and Remus. Valved systems such as the Milltek Resonated and Valved Exhaust keep a quieter mode for daily driving.

A downpipe replaces the section directly after the turbocharger, and we carry catted options such as the AMS Performance Street Downpipe and the HKS Front Pipe with Metal Catalyzer. Check each product page for emissions information and any calibration requirements, and contact us before ordering if you are unsure.

The GR Supra downpipes we carry are catted designs, the AMS Performance Street Downpipe with GESI Catalytic Converter and the HKS Front Pipe with Metal Catalyzer. Check each product page for emissions information and any calibration requirements, confirm your local emissions rules, and contact us before ordering if you are unsure.

Under the Magnuson-Moss Warranty Act, a dealer cannot void an entire factory warranty simply because aftermarket parts are installed. A specific claim can still be denied if a modification is determined to have caused the failure, and ECU changes are detectable. Warranty decisions are made by Toyota and its dealers, not by LIMIT+1.

Every product page lists the model years, trims, and drivetrain configurations the part is built for, and every collection on this site is organized by platform. If your vehicle carries other modifications, or you are between model years or trims, send us your year, trim, and current setup before ordering and we will confirm fitment.
