I'm trying to choose between Quadratec's Super Turbo cat back exhaust kit and Rusty's system with the 50 series Delta Flow. The Quadratec kit is $20 less.
The Quadratec cat back is the Dynomax system. You can get it cheaper from Summitt Racing. 95 shipped. One problem, it doesn't come with a tip for the exhaust. The Rusty's Flowmaster is the way to go with the power increase and the price isn't bad when you look around when the average is 250.00. Go with the Rusty's.
