Clear DayI have a 2001 V-6 Mustang Convertible. I've made some modifications to the intake system. It's time to turn my attention to improving the exhaust system. The following list are my options.
- Only add a higher flow muffler (Flowmaster, Edelbrock, etc.)
- Replace the pipes after the stock exhaust manifold with a cat back system with H-pipe and dual or single exhaust.
- Replace the stock manifolds with short headers and finish it with #2 described above.
I understand that long headers are not legal in CA. They eliminate one of the required sensors.
My question is how much performance gain can I expect from each of the stages described. Will stage 1 provide the largest improvement causing the others to offer less bang for the buck?
Appreciate any input.
Thanks,
