exhaust question

What is the sound difference between flowmaster catback system and just having the flowmasters dumped? which is better? Any peformance difference?

Dumps are noisy and will make your whole car vibrate inside. You won't get much of a performance increase by running them on a car that's stock or with light mods.

My first mustang was a 98 gt. I had dumps on it and I did not like it at all. Run the pipes straight out the back it looks alot better. Get the PI head swap kit to notice the biggest difference in performance.

With dumps, the sound is amplified by the ground and undercairage of the car. Personally, I prefer the regular tailpipes as opposed to dumps
