As the title says, I'm curious to see if anybody out there has this muffler, part # 115300 I believe. I went to my exhaust guy, and he told me that this is the deepest sound application that he's ever heard on a LT1. How come I've never heard of it!? He did say that they're outa canada, so maybe thats it...seriously though, I looked at the muffler, and it was a straight though with lil baffles type design. I'd appreciate any feedback on this. Oh, and I'm up grading from a flowmaster muffler, so any suggestions of a muffles that would compliment edlebrock shorties, into a random tech cat would be appreciated. Thanks fellows.
