What do you mean? You asking if the gt500 mufflers would sound good on a sixxer? I thats the question id say there probably wouldnt be too much of a difference. Plus youd have to fabricate a connection between the 2.5" pipes of the v6 to the 3.5" pipe on the muffler

 

Yes it does make a difference. I sold my gt500 ab's to a guy with a v6. He loves it. I think his name on here was Bucko.

 

Sure enough there's a video on YouTube of a 2011 V6 with them on it... Sounds good, like a potent V6 but pretty **** good!

 

A properly cared for significant other will prevent static from the other seating position in the Mustang.......allowing one to modify as needed.
