So I am looking into Vibrant Performance Street Power mufflers for my Mustang. I have always been a HUGE fan of Vibrants products. I am going to run their #1126 muffler with their 4" rolled tips #1303. The only bad thing is that the tips are 2.25" inlet, but i'll have the muffler shop open them up to 2.5" to work with the mufflers and such. I am really looking forward to doing this setup as I haven't seen it done on a mustang yet. I'm sure that I won't be doing this for a little bit as I am going to wait until I get my 3dcarbon ground effects.
