Flowmaster American Thunder catback for 11 GT

[Michaelj55mp]

Has anybody added an American Thunder catback to their
'11 GT? Listened to a comparison of axel back vs catback American Thunder's
and the catbacks seem to sound much better. Any thoughts?

I have the American thunder axle backs and the heartthrob h pipe without the resonators and it sounds deep and loud.

JLT CAI, Lethal o/r H pipe, Flowmaster AT 40's axleback & Jon Lund 93 street tune.

I just wanted the old school setup, Gonna get an HD video up soon on YouTube under wicked400ex

My exhaust is completely stock except for the American Thunder axle-back. Love the sound and one of the cheapest axle-backs as well. Win-win in my book.

Here's a youtube vid of it from latemodelresto

Hi Parchisi,

I'm looking @ different exhausts and have seen the LRS video of the American Thunder Axlebacks, but I suspect that car has something else besides just the A/B - does yours sound like that?

You'll be happy to hear that the car in the vid was less than a week old with only a couple hundred miles on the odometer. The axle back was the first & only performance mod installed, still to this day!
