well all i can say is maybe i should of left the block off disc in the center of the muffler, anyway i looked thru the muffler and saw it wasent straight thru so i decided to take a 4.5" holesaw and make it see thru, well it definately isnt as quiet as my straight thru donaldson i had on my 04.5 4" system, any one else do this and have the same results i havent pulled with it yet but it barks pretty loud when empty so we will see. The muffler is 5" id both ends, and total length of 40" and body size is 9".

Check this out & see if it was the same muffler inside. I think they are cross-referenced in by exhaust shops.

no the muffler is different mine had a total block off disc in the center of it, no holes drilled in it of nothing, so the exhause had to go around the outside shell of the muffler instead of going thru the center straight through.
