Hello, I'm looking to replace my exhaust manifolds since it have 3 busted bolts. I have the stock exhaust system and would be looking for bolt on headers (shorties). It seems hard to find shorty headers for a 2015+ chevy 2500hd with the 6.0L gas engine. Has anyone made this switch or have any suggestions? Are they the same headers that fit on the 5.3 and 6.2L? Thanks.
