That thing is great!
Can you go into more detail about the exhaust? size, crossover pipe, out the back, axle dumps? A revving video would rock too. I really want to get those mufflers but I have not heard them on a small block.
I've got a 318, headers 2 1/2" exhaust, x pipe and thrush welded (flowmaster 40 series copy) and it runs out the back. It just seems too darn quiet! Darn x pipe quiets it down so much.
Yours sounds great at idle I would like to hear it revved up a bit if possible!
