Do you recommend taking away the cat from a stock exhaust?
You're better off getting a high flow 50-state. They're cheaper than the stock replacement, louder, and cleaner. On top of that, cars that are built with a cat are tuned to run with the small amount of back-pressure generated by them. So if you remove that back-pressure, especially if you're running a straight through muffler like a glasspack, you will actually lose power. On top of that the people who drive behind you on the road will think your a mega-douche, I would.
