Hey everyone. I have a 2004 Mustang V6 and I want to get a dual exhaust system to give it that aggressive sound. If I were to buy a true dual exhaust system, can I buy a GT made exhaust system, or do I specifically have to buy it marked as V6. Because I read online I could just smack on a GT after market exhaust system. Is this true? Does it make a difference?

Take a look at the tech articles contained on this forum. Lots of Mustang modding information created by real Mustang owners. Follow this link:

But basically you need one of the following to get a dual exhaust:
1. Y pipe dual conversion kit. Comes with everything after the cats. Not a true dual exhaust.
2. A full v6 true dual exhaust conversion kit. Comes with everything after the headers.
3. Replace the Y pipe with an X or H pipe. Then you can use a GT take off exhaust.
4. Custom shop to make one for you.

If you grab the exhaust from the cats back off of a gt in a parts yard and carry that to a shop they should be able to fab the rest of a true dual setup cheaply and pretty quick. On a v6 you want an h pipe, an x pipe is more raspy.

If you do grab the GT tailpipes make sure you grab all the hangers as well.
Also grab the bolts and clips to install the hangers.

Dual exhaust on a v6 is a waste of money

If you do true duals, no it's not.

Why do you think it is a waste of money? Please share!

If you want a mellow rumble, you might want to consider the Flowmaster American Thunder exhaust kit from American Muscle. Match that up with the Pacesetter H-Pipe adapter to connect the exhaust to the stock headers. I've spent the better part of a year trying to decide what exhaust I want done to my 04 sixxer, and plan on getting it done at tax time next year.
