??1981 L81 Dual exhaust??
i currently have dynomax super turbo mufflers on it and a high flow cat, i have read that most people take the cat off of this car.... will it really make that much difference? and has anyone cut a pipe and installed true duals on their vette? if so help me out

I just dropped my Cat the other day! Straight piped back to the existing 2 year old mufflers, and it made quite a difference. Smoothed out the engine, and added a little kick! It also opens you up for future mod's.....the more you can exhaust, the more you can put in! Translates to increased HP!!
