Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

We are proud to introduce our Performance decatted downpipe for your G42 M240ix, G20 M340i, G29 Z4 M40i & A90 Toyota Supra

Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our race DE-CAT which results in faster spool, an increase in power & a more aggressive exhaust note. Our downpipe features a full 4.5″ stainless steel design as well as a cast elbow, oversized flexi with T304L grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes. All downpipes are made with T304L grade stainless steel and include a lifetime warranty

Please note that the warranty on the catted downpipe is limited to one year.

Made from hand crafted, tig welded 4.5″ 304 grade stainless steel.

Available also as a 200 cell high flow cat

Fits RHD and LHD models with no modification necessary.

Smooth radius bends to decrease turbulence and increase flow.

Fits the stock catback as well as all aftermarket catbacks.
