I have an 89 maro... for anyone that got the flowmaster american thunder exhaust system, did you have any problems with it not fitting right?

 

I had no problems with my America Thunder system fitting on my IROC. The system is tight going over the axle, but I am sure that all 3" exhaust will be that way. Other than that, make sure you don't tighten anything down until the whole system is on so you can adjust it a little bit here and there. Later

Put the American Thunder 3" system on my 92 RS.Fits good, though a little snug over the rear axle.Sounds great too! Not as loud as I thought it would be. Installed it myself in about two hours, took it to the muffler shop to have it welded up.

I have a Flowmaster 80-series (American Thunder) system on my 305TPI with a 3'' intermediate pipe, and a stock cat. It's not as loud as a Mustang Cobra with true duals, but the deepness & tone is really nice. I have a friend with a $700 corsa system, and mine has more "bass" tone, if you will

I'd definitely recommend it!
