    And they told me they would not guarantee that any other brand would fit, although I have heard of one or two that will...marketing gimmick.

    But yes, they are definitely of high quality.

    Shorties will fit as well as the swept back headers, but they will not perform like the DSE headers. Might as well have a exhaust manifold

    I have the speed engineering shorties. They fit great and worked with my budget ($150ish). I have the dirty dingo adjustable mounts. Good clearance between the frame where the truck manifold flange would hit.

    Do you have pics? $150 is dirt cheap for steel headers.....Stainless would be ridiculous at $150. How thick are the flanges?

    FWIW I have the Holley Hooker Exhaust manifolds on my car and they fit really nice. They are based off the 2010 Camaro exhaust manifolds so I can see the shorty headers for the 2010 camaro fitting just as good.

    I bought some of those speed engineering shorties before buying my Holley manifolds and had a hard time getting the drivers to fit. It was hitting the lockout rod and close to the steering shaft. I beat the snot out of the flange area and a tube to get it to quasi fit. But in the defense of the headers I have Holley mounts and transmission auto crossmember on my car and it sat the motor back and off to the drivers side...a lot. But I think in a normal application it would be fine.

    Speed Engineering doesn't list the Ls7, would that be because of the Ls7's 'D' port, I know these long tube headers will fit but the Ls7 exhaust port flange is a bit different. anybody?

    You should be fine, I've been using DSE headers on my LS7 heads for 5 years.

    Thanks for your input, DSE headers are a nice piece of work for sure but also 3500 bucks in my money, even for you guys in the states they're not cheap! looking at Speed Engineering and Hooker/Holley
