my 51" Donaldson had developed a hooting whistle that I thought was my friggin' ring and pinion it was so loud!
so I ordered a Corsa muffler and had Summit price match the best price I could find... but it won't ship till March (backorder)
Spent yesterday laying down like 4-5 layers of RaamAudio sound deadener. ZERO friggin' difference in interior resonance!
so I said F'it and ran 4" straight from the downpipe to the 5" tailpipe. It's louder inside, but not too bad. The annoying resonance is pretty much GONE!
let me attempt to describe the sound of this thing... just putting around in the 1300-1800 range it sounds a bit like a 2nd gen 24v... but give it some throttle and RPM and it's a mix between a cracked out Cummins sled puller turning 5000+rpm and an old 2 stroke Jimmy!
I'm going to go through a LOT of fuel this weekend listening to this thing.
I can't IMAGINE how loud it would be with a wastegated turbo
