I see that Flowmaster has a new kit that is a cat back kit. Has someone ran one or saw one on a truck. It is the American Thunder muffler.

 

I have seen this kit before it uses the suv style one muffler two in two out. I had this welded in on my stock exhaust it sounded great. Not as good as the new bassani setup The only thing that is weird about the kit is the tips the are straight cut. I had a pic of it but cant post it. they have a pic of it on truckperformance.com

has been in business a long time they have yet to come up with something decent for our lightning LOUD sounding exhausts do not make horsepower. in fact you might even lose low end or high end torque???? just my.02 worth peace bro.
