Changing up the exhaust a little and I need some help/advice. Currently I have an O/R H-pipe to Flowmaster 40's(typical obnoxiously loud Mustang exhaust). I'm looking to switch it up to an O/R X-pipe to a set of Magnaflows. But my question is, which mufflers do you guys recommend? I'd like to get the ones from the cat-back kit but I don't know a part # for them or where I could buy them from other than Magnaflow direct.
