            They sound okay. Classic muscle sound but too quiet for me. And the fitment sucks. I have to get the tail pipes extended cus its blowing exhaust onto the bumper.

            Easy install, not as loud has i predicted.

            The install was pretty basic everything bolted right up. i recommend getting your own set of hangers, the ones it comes with are pretty cheap. exhaust isn't has loud has i hoped, but it still flows better then the factory one

            Flow master a.t catback

            Had the same product before on a 95 gt. With h-pipes. Great set up and nice exhaust note. Just got ahold of a 94 gt and am for sure putting the flow master catback paired this time with the off road x-pipe. Hade no problems with ugly drone and if u step on it she pops nice.
