i put the airforce1 on and now am ready to do some exhaust thing. if i only change the factory muff to a flowmaster 40 -what will i get. i dont want to lose low end. but would like to add a little sound. i dont race around just want it to sound better and maybe be a little less restrictive,

I'm not trying to be rude, but you should really consider doing a search before asking that question, the thread goes on and on. Each setup is different for different people. good luck with the search...

You might consider a SpinTech muffler. IMO, they sound better than FM. I have one on my SCrew and plan to switch my Mustang from FM to SpinTech as well. I want to get rid of the drone and metal "ting" sound of the FM. Gibson is also a nice mellow muffler that performs well. I have that on the Burb.
