Do you have an h pipe installed? RICK
I actually did the opposite of this...haha. The Nova had dual Dynomax mufflers on it when I bought the car, and they were way too quiet for me. I scrapped them in favor of Flowmaster, and it sounds perfect to me now. The Dynomax would have been nice for a daily driver that gets fired up every morning at 6am, but for a weekend car they just didn't cut it for me. It's funny how subjective our opinions can be on sound.i bought the flowmaster american thunder system that had that type of muffler and it was way too loud for me. i know you listed the number i didnt know it by number just the name. i took it off after about 25 miles and could not even give it away free. had to scrap it . i went with the dynomax mufflers , and am finnally happy with the sound..
