Please note we cannot make guarantees that the check engine light will not turn on with this downpipe. You will likely need an aftermarket tuner ECU as well still

Our shop GR SUPRA has the SupraStore.com downpipe and to date no other downpipe has produced more power. Let's be honest though, most any downpipe from a quality company is going to produce similar results. The B58 engine is very responsive to the installation of a downpipe.

The CATTED downpipe helps free-up quite a bit of performance over the factory original factory downpipe. Anytime you can reduce back pressure from the turbo, you're going to gain power, this is the concept behind a performance flowing downpipe.

Many of our customers prefer a CATTED solution for emissions, piece of mind, and the elimination of any check engine lights (CEL). We offer the single best valued CATTED downpipe for the GR Supra. Spend less for the same quality and performance.

The CATTED downpipe utilizes 4.5” diameter stainless steel piping in order to provide more power, quicker spool, all in a robust platform. Bolts right up to the factory or aftermarket exhaust using the OEM slip joint. It's exactly what we run on our shop car.

Why buy from SupraStore? We have a full time staff of Supra enthusiasts and invest back in our employees and the cars that you actually drive. This variant of our Supra MKV downpipe utilizes a high flow 49-state legal EPA approved high output catalytic converter that allows vehicles to pass emissions testing for street use.
