Just won a set of BBK shorty headers and a dynomax super turbo muffler. 2.5" in/out. Just gonna swap them onto my dads old kitty once they arrive. Its a cfi set up which he likes(me, not so much) and he won't let me convert it so I just wanna help it flow alil better and def sound better. He doesn't want it loud(he's 67 and has a lead foot still) haha. Anyways, I was thinking just the muffler swap(its a single exhaust) and the headers will make the cougar growl better under acceleration. Also, I noticed that his tailpipe is only 2" past the muffler. What gives? I think I'll just take it to my buddies shop and have him do the whole install and bend me a 2 1/4" tail pipe to replace that 2" rusted one. Never thought a 5.0 power plant would have such a wimpy tailpipe. But thanks for the input as to a good quiet performance muffler. My choice was a borla pro xs as I love them but heard the super turbo was a hair quieter.
You guys continue to rock and I love reading these post and def following the build threads
