  Deep and Loud

  I have had this catback on my car for 7years now and everyone is amazed how deep and loud it is. But this is when fitted with a O/R mid pipe. I have an O/R bassani X and with the catback I have no rasp. And at ideal its louder than my friends 40 Series with O/R pypes X. But I will say it drones at certain RPMs. But the deep rumble makes up for it. I'm about to switch to an H-pipe to get an even deeper rumble from it.

  long term update

  Great fit and sound, but does not hold up long term. A baffle came loose in one of the mufflers after 3 years (rattles) and a pipe rusted through at the H pipe joint at 6.5 years. This is with full time use in Kansas weather.

  Force II on 2002 Mustang GT

  This exhaust was a great choice! If you're looking for an exhaust that isn't too loud but still has a great deep tone, this is the one for you! It isn't too loud where it scares people but it's enough to make people turn their heads! Great product!

  Gives your V6 a deep sound

  I have installed this along with BBK Headers and off-road pypes x-pipe and with these 50 series give my 3.8 a nice deep tone that i love. Fitment...take some elbow grease to get it fit nice, i had the back exhaust slightly touching my axle but not too big of a deal. Real great product, good shipping and good quality. I would deff buy this again. The tips look great out the back and the sound is deff a head turner. Thank AM!

  A great product for an amazing price.

  This exhaust was a perfect fit for my '02 GT. I jacked the car up and was still able to install it with no difficulties. It looks great ad sounds nice a throaty, just like a mustang should. It isn't very loud so you can actually hear other things inside the car, but is still loud enough to stand out from others.
