Flowmaster Amercan Thunder

I purchased the Flowmaster American Thunder exhaust from Auto Anything with a 20% discount and rebate. I also purchased the BBK o/r x pipe. Had it installed in couple of hours and sounds great. Now my 04 Mustang GT sounds like it should.

Hot Ride!

Buy these pipes, you won't be disappointed. I feel bad I had Superman put in new speakers because I like listening to the pipes more that I do the stereo! These put out a nice deep rumble, especially driving at 2000rpm. With or without the top down I can hear them and it's a perfect sound. Not crazy loud just deep and tough.

Love it

Taking off the old exhaust and installing the mufflers was a breeze. Not so easy with the tail pipes though. Had the jacks on 2 blocks of wood and still couldn't get the right angle to install them. My mechanic did it real quick once it was on a lift. Sounds awesome, but has some drone.

This exhaust system is great looks good and sounds good. I can definately feel the Hp boost. I would suggest taking your ride to a muffler shop. Took them about thirty minutes to take off the old ands install the new.
