Flowmaster Axle Back System 2005 - 2010 Mustang GT/Shelby/GT500

To answer 313xdetroit I think the popping noise comes from the tune because one shop that I dyno tuned at I could hear popping but not at the other shop. I have the HushPower pro series shorties and I am happy with them. Did not do a before and after dyno with these.

on a 2010 gt.....which is louder....the 409s or the hushpower? Also does either have a raspy tone once you hit the high rpms and is there any of that popping you get in some exhaust in this exhaust or the 409s?

Man I love Hushpowers mufflers I've got a Super 40 with turn down but it's not really loud and aggresive like I wanted it to be when I get money I'll be geting the Hushpower Pro Series muffler

im not trying to sound stupid, but as a pontiac owner i gotta ask....where is the love for the firebird family??? i hav flowmasters on my 1990 firebird but i see 0 videos on the flowmaster channels about a firebird

@lilwizz200 that's because nobody likes firebirds
