FS Flowmaster American Thunder v6 axlebacks

[kenredconvert]

I purchased my 2011 1LT convertable this September and immediatly ordered the American Thunder 817483 axle back system for it. Although I had American Thunders on my 2004 GTO and loved them, I find that they are too loud for my ragtop. Also, I would not sell them to anyone who has the 2001 or 2012 convertable because the pips will not fit under the rear cross bracing whic is specific to the convertable unless you also want the beefer 1/4"x1-1/2 inch braces that I had made up to loop under the pipes ( no extra charge for these. Asking $400 since I only had them on my car for 2 weeks
