I have had 1 exhaust sistem on mi 02,03,04 trucks. looking at mi 06 looks like it shuld fit w/o cat. Im going to wait till spring to change it.I want to get a good feel for stock.And see if there is a big difference in EGTs & power
The cat back kit for the '01 - '05 will not fit the '06 truck without modifications. If you use a cat delete pipe and exhaust from an '01 - '05 truck complete is will fit. We have them all so it's kind of a your choice deal, if you want a cat back just buy the '06 unit and bolt it in place.
The LB7 and LLY systesm will fit an LBZ, but you will NOT be able to remove and reinstall the cat as the LBZ ca tis a different dimension than the early trucks. We stock all the MBRP LBZ kits that will allow you to go cat back or replace the cat pipe and then reinsert the stock cat anytime you want to. They are available in aluminized, 409 and 304 stainless in singles and duals too. Call us if you have any quetsions etc.
