Attention: TDR Forum Junkies Ok, I have been doing a lot of research on this topic. My problem was the noise. I installed my 4" stainless exhaust turbo to tip to lower my EGT,s. When I put the system on I was very unhappy with the bark it had at WOT. I have called almost every muffler and exhaust shop and company there is to call. Nobody has a 4" in and out stainless muffler to quit the truck down, unless you went with aluminized. I have FINALY found MY perfect answer to an exhaust system
I called the guys at Hog Performance Exhaust and talked to them about their "Autmentor" muffler. I had them send me one. It sounds great. It has a deep sound to it and sounds great out side of the tuck, still louder that stock. you can bearly hear it inside the truck. 
It is still a straight through muffler but it has bigger luvers and a seperate air chamber.
Did I also say it sounds unbelievable!!!!
