Invidia Downpipe Bellmouth Catless - 02-07 WRX/STI

Have a race car and looking for a way to make instant horsepower? Invidia’s downpipe is always a good start. This particular downpipe was tested and documented in the late but legenday Turbo magazine. They concluded that when combined with the cat-back section, the HP gains were seen up to an astonishing 60+ at the wheels with engine management.

This downpipe is made out of 304 stainless steel with a larger bell mouth. The piping ID is 3”, and should bolt up to most catback or stock units.

Please note that because this product replaces/removes an OEM emissions control device, we must state that this catless downpipe is for off-road use only.
