Although GReddy is known for our famous cat-back street exhaust, GReddy got its start in racing exhausts. After numerous customer requests, we have decided to release a line of race inspired exhaust systems. Not satisfied with just offering another free-flowing, large diameter piping with minimal bends, GReddy has decided to offer the GReddy Racing Exhaust in full Titanium; that's an 80mm cat-back system that weighs as little as 10 lbs.
