Great sound, not annoying even with baffles out.

I already had the GT500 axle backs on my stang and even though they are an improvement over the stockers, I wanted my exhaust note to go up just a notch. I didn't buy mine from AM but got it from an actual ...

Had it installed at a local shop and when I heard her fire up and you couldn't knock the smile off my face. Well worth the money.

My state has CARB compliant requirements. Is this 50 state legal?

  • The Ford Performance Boss Style H-Pipe and Side Exhaust installs after the factory cats, making this exempt from CARB compliance.

Can somebody please tell me if this can in anyway possible be made to fit on a 2012 GT?! I have been searching for every to try the proper one and i just cant! HELP!

  • The Ford Performance Boss Style H-Pipe and Side Exhaust (11-14 GT500) is only designed to fit on 11-14 GT500 Mustangs. You can get this Exhaust System to work if you have some modifications done like welding and cutting. This will not be a direct fitment. The Cervini's Side Exhaust Kit (10-12 GT, BOSS) will be a direct bolt on to your 2012 GT. This kit comes with the side exhaust as well as the side skirts. This way you do not have to do any drilling or cutting to install the exhaust into the skirt.

Can this fit on a 2013 GT ? There used to be one listed on the site but this is the only one I see now.

Ross12

  • The one for the GT has been discontinued by Ford Racing I was told. Don't know why. You MIGHT get lucky searching around finding one that was bought but never installed, but that's about it unfortunately.

    Great sound, not annoying even with baffles out.

    I already had the GT500 axle backs on my stang and even though they are an improvement over the stockers, I wanted my exhaust note to go up just a notch. I didn't buy mine from AM but got it from an actual boss 302 that was removed for an aftermarket h-pipe. The first thing I did was remove the restrictor plates for that full exhaust flow and sound. After several hours and curse words trying to remove the bolts from the front of the h pipe, I decided to take it in to an exhaust shop for installation. The guy that installed the exhaust only charged me $50 and told me it slipped on like butter. Overall it picked up where the GT500's left off, sounds way better now and is a bit louder/deeper but not abnoxious. The exhaust note at WOT reminds me of an old carb'd V8 when floored, very old school sounding (that's a good thing). Only time you'll worry about waking the neighbors (unless you hate them) is on a cold start, besides that they're not too loud. I just got back from a 5 hour road trip and not once did this exhaust system bother me even though around 75 - 80 mph it does drone a bit. Performance wise I say little to none as I noticed no hp/tq gains from the butt dyno. Is it worth $850? I'd say find a used one first before paying full price because I did not pay close to that at all for a used one. If I did buy at full price I would still say it would be worth the $850 price tag.

    Excellent throaty sound

    Purchase this for my 2014 GT convertible along with Flowmaster outlaw axle back installed the axle back first was pretty impressed with the sound couple weeks later installed the quad and was blown away absolutely impressed with the sound if you like a nice sounding car you will love this exhaust. Installed the axle back myself took about 20 minutes took the quad into a shop I didn't have a lift to install it myself but the guy said it was no problem at all and went right on with out problems took him about 45 minutes including the time to jack up the car
