If you are searching for the ultimate cat-back for your STi, look no further. The addition of a WorxTuning Cat Back Exhaust Upgrade will provide a deeper, throatier performance sound without the uncomfortable resonation associated with many performance systems on the market. Throttle and boost response, and overall performance is noticeably improved due to our free flowing design. The fully polished stainless system looks great too.

3" Construction with factory style connection at mid pipe

Slip fit joints with t-bolt clamps for install ease and weight savings

Includes all necessary clamps and hardware

Made in the USA with a LIFETIME WARRANTY

Note: This system is manufactured exclusively for WorxTuning by GHL Motorsports, a leader in US Made performance exhaust systems.

The system is backed by GHL's LIFETIME WARRANTY
