Hey has anyone heard of these Flowmaster American Thunder mufflers? They sound nasty in the video clips ive seen but are also going for $240 bucks for a pair from Mustangs Unlimited I always thought these were just delta 40 series or something but called American Thunders, but I guess they are different...Any feedback on this?
I have American Thunder mufflers on my 86 and it is louder than anyother stang i have had, I think it is the loudest mustang that i have heard in person actually, I highly recommend getting a set of American Thunders.
ive heard them...nothin special in my opinion...just a typical 5.0 sound just louder...heard them on a 00 GT...sounded nasty...but like i said...flowmasters are played out just like cobra r's on fox bodies lol...honestly...i had magnaflows on my car...i dno if you ever heard mine with em...but they sounded sick...quiet at idle...but when you got on it they opened up and soudned real nice
I had a complete 2 1/2" Flowmaster American Thunder cat back system on my 90 L.X. for years. Had an off-road pipe and 1 5/8' shortys too. The car wasn't that loud. I never got a headache as there was no drone. Just had the typical 5.0L sound.
