Are you talking long tube headers or shorty headers? If you find shorty headers to install it can be done, not sure why you would want shorties, but to each is own. If you're referring to long tube headers, the answer is no. Long tube headers require a totally different hpipe that is shorter.

B&B longtubes can be installed on the stock H-pipe.

I would have to imagine that they would since they mate up exactly the same as each other and I believe are interchangeable.

Shorty headers provide very little gain over the stock manifolds for the cost. I would guess that you could pick up 10rwhp tuned out of shorties where you can pick up 25rwhp tuned out of longtubes. Our manifolds are not terrible from the factory. I'm not sure anyone still even makes a shorty header for us...callaway did but scrapped it because it didn't make much power.

Going with Z06 manifolds is a cheap improvement over stock though. I happen to have a set available if you're interested

I installed a 2007 ZO6 exhaust system (headers, cats, "H" pipe and NPP mufflers) and ported the intake manifold on my 2007 Coupe and picked up 30 RWHP

Only long tubes are B&B, and they delete the cats. We sell them here-
