Which Exhaust Set-up Provides the Most HP for an ’06 GT?

Ford Mustang Q&A

Karl A asked: “I just purchased a 2006 GT convertible. I really want to put a lot of time and money into my new car, not only to make it look good, but powerful too. The first thing I want to do is upgrade my exhaust. I’d like a strong old school muscle car rumble and growl but I don’t exactly know where to start. I have been told to get Flowmaster axel back mufflers with cross pipes. I have been told H pipes are good, and many other options. My goal would be for extra power, and of course, a loud, muscular sound. I would appreciate any advice here. I want to put work into my new car and do it right!”

An aftermarket exhaust is a great place to start when modding any car. A complete system can add an extra 40 hp at the rear wheels with a tune. Our tech article on understanding exhaust systems is a must-read for any first-time modder. Before I get into the nitty-gritty of exhaust systems, here are some important points everyone should know about aftermarket exhausts:

  1. Purchase your headers and mid-pipe from the same manufacturer – some manufacturers sell products that only bolt up to their own, or OEM, exhaust components.
  2. Long tube headers sometimes require oxygen sensor extensions, but always require a new mid-pipe (shorty mid-pipe).
  3. If you choose to run an exhaust with no catalytic converters you will need to re-tune the computer to get rid of the check engine light.
