TurboXS Stealthback Exhaust - 2008+ WRX/STI

Want to get the most power from your 2008+ WRX or STI without attracting the attention of the authorities? This modification replaces the restrictive factory downpipe and catalytic converters with a 4.5inch cast bellmouth that tapers into 3inch pipe which bolts directly to your factory or (most) aftermarket catback exhaust.

note: Not to be used on pollution controlled vehicles that will ever be driven on a public road.
