The COBB Titanium Cat-Back Exhaust is un-matched in build quality, style, and performance. Utilizing Grade 4 titanium tubing, this cat-back offers high corrosion resistance and protection from impacts. Back purging ensures quality welds that will not fail due to contamination. The entire system uses slip-fit connections, allowing for a wide range of adjustment. Blued titanium tips add a distinct touch and offer adjustability. Best of all, this complete system weighs in at 24lbs assembled, nearly 50% lighter than it's stainless steel counterpart.

Note: Are you using a stock j pipe or downpipe? If yes, the GrimmSpeed Subaru Stock DP to Aftermarket 3 in. Catback Adapter p/n 077046, is required.
