01-06 Duramax Muffler Replacment Pipe

 

This muffler delete pipe is different then the others on the market because we take 4" tubing and downsize the inlet and outlet to 3.5" so it is easier to attach. You also get the benifits of having a 4" muffler replacement pipe instead of the stock 3.5".

 

This item includes 2x 3.5" muffler clamps so there is no need to run to the parts store to get the rest of the nessary parts for your install.
