Subaru Full 3" Hi-Flow Exhaust System - WRX ('02-'07)/ STI ('04-'07)
After evaluating many of the leading aftermarket exhaust systems for Subaru, we designed our own WRX / STI exhaust for maximum performance and superior sound.

Substantial horsepower and torque gains, along with improved throttle response are achieved with our free flowing, unrestrictive 3” straight-thru Hi-Flow design. This well engineered exhaust results in a perfect blend of sound, power and performance!

3” stainless steel piping is utilized throughout, including the outlet pipes, which reduces back pressure and enables quick turbo response. The Speedtech WRX / STI exhaust is available with either a “cat-less” maximum performance down pipe for off road and track use or with a catalytic converter for emissions compliance. SpeedTech 02 bung extensions are optional and will prevent the CEL from registering when using our cat-less downpipe.

The Speedtech Subaru WRX / STI exhaust will improve the sound and performance of any WRX / STI, whether stock or highly modified. Increased torque and horsepower, faster track and Ό mile times, better everyday performance and a more pronounced engine note will provide an enhanced driving experience for all types of uses.

High quality stainless steel construction - this is a very well built exhaust!
