3" exhaust w/ down pipe. Carbon Fiber wrap around muffler- Titanium tip (2005 subaru sti)
Exhaust is catless-
-The o2 sensor still attaches via an L shaped flange, no engine light or emmision issues
-A resonator replaces the cat making the exhaust quieter- not deafening at all.
-Still has a great ripping sound when you get up in the higher rpms (and has the great subaru rumble)
-Performance is great, especially with the down pipe. (not sure on hp gain)
-Looks: Muffler angles out, agressive look, titanium tip and carbon fiber wrap around muffler.
-No clearance issues, bolts on fine.
over all- I'd give it an -A-
