In the tradition of their top-notch quality performance exhaust systems, Invidia has released their catted and non-catted performance 3-inch downpipes for the Evo X. Designed from full mandrel bent and mirror polished stainless steel, this downpipe will exponentially increase exhaust flow and enhance power throughout the rev range in your Evolution. CNC designed and computer welded 1/2 inch flanges resist warping and will ensure that you and your Evo will enjoy many years of worry-free performance. The Invidia downpipes are designed to bolt up to any aftermarket or stock cat-back exhaust system and seal seamlessly with the stock turbo housing for a perfect fitment. Invidia downpipes for the Evo X are available either with or without an integrated high flow catalytic converter.
