Well when the truck was close to stock i added a Dynomax 3" intermediate pipe(flanged to hook to stock Y) and a single 3" in/out Hooker Aerochamber dumped at the axle and the truck sounded awesome. Then i added the LT's and Y-Pipe and since then it is is NASTY... Entirely too loud and not a good loud... that raspy glass pack nasty loud. Any one recommend a quiter/deeper muffler? Maybe a Magnaflow or Dynomax Ultraflow??

 

Everyone is going to recomend a large Magnaflow..I spent 4 months tracking down a Corsa Touring muffler and could not be happier...

 

ya prob a 22" magnflow would be good
