TurboXS Bell-Mouth (Stealthback) Downpipe (08+ WRX/STI) TurboXS calls this their "Stealthback" exhaust, but we call it a two-piece downpipe because most people think of it that way. Regardless of what you can it, we think this is one of the best downpipes available for the 2008+ WRX and STI. It uses a full 4" cast bell mouth section on the turbo side, tapering to a 3" mandrel-bent stainless pipe.
The downpipe is sold with either a TurboXS Race Pipe or a TurboXS High-Flow Cat (see below) in order to reach your factory or TurboXS cat-back exhaust. You can buy each of those a la carte if you later want to switch to the other (race pipe or cat pipe)
We've had a few people inquire about just buying the front half of this downpipe, as a "shorty" downpipe to fit their factory cat section. That's not going to work; the front half of this downpipe is designed to fit the full 3" TurboXS race pipe or cat pipe ONLY.
Please read our FAQ page on catalytic converters before purchasing this part.
