What is the best performance muffler
After much investigation my idea was to buy a Cat-Bypass Pipe for my EURO/ROW Porsche 911 3.2. Then I found out it would only give a couple of HP as, my model doesn't have a Cat. So, does anybody have any say on what is the best sport muffler for my car. Or any comments on the above.
