Any performance muffler is going to give you HP over stock mufflers, but face it, we are already expelling exhaust from only 231 CI of air thru two 2.25" mufflers. My stock 302 V8 mustang had two 2.25" mufflers. I dought if just a muffler swap would give any HP on our cars at all. Most guys swap mufflers just for a little rumble. If you had a single muffler car, the performance muffler would definitely give you some kick. Bang for the buck I believe would actually be the magnaflow DP with hi-flow cat for $130 from performance peddler.

The stock catback while not pretty does the job pretty good. So don't be expecting any gains when changin mufflers. x2, you wont gain more than 1-2hp. if even that much

Go back to Nov 13th post "Magnaflow direct fit cat" or search for Peddler. There is more parts info in that post you will need. http://www.performancepeddler.com/SC_out...ND+PRIX&sCtrl=Y
