2007 Sierra 2500HD Exhaust Question


07sierra8.1

Question

Hello,

 

I got a 2007 GMC Sierra 2500HD CLASSIC SLE w/ 8.1L Motor in it...

 

The previous bone head owner of the truck cut into the Stainless Factory exhaust at the muffler and put an aluminized system and aftermarket muffler on it which rotted off shortly after I purchased the truck..I took the truck to our local exhaust shop and had another aluminized dual exhaust put on it...This lasted me about two years and is now rotting back off again...

 

Every other Sierra with the big block 8.1 I have come across and looked at...their factory exhaust is made alot differnet than what is left of my factory exhaust..which is basically from the muffler foreword. Theirs has both left and right side of the exhaust pipes from the motor going into the muffler..as to where Mine "Y" together shortly after the cat converter and then there is about a 3-4 foot by 3.5'' diameter intermediate pipe before what would be where the factory muffler was....with a two bolt flange style connector attaching it to the Y pipe I mentioned.

 

My question is... Is there any possible way...that my truck somehow got the newer body style exhaust system under it before they made the acutal change to the body considering my truck is a mid-year truck (thats at least what I call it when they change body styles half way through the year)??

 

 

I have looked on ebay and other places for exhaust systems...what they say will fit my truck...does not at all look like what is under my truck...and what they say will fit the newer body style trucks...looks like it would bolt right up....
