What does the class have for rules when it comes to the manifolds, can you run headers does it have to be ag type do you want the exhaust
to come out the same hole do you have to run stock cross over ect.

Supposedly the 7810 style dynos a little better than others. If you want to get turbo out in front of engine a 7700 non turbo combine works well. If rules allow I think header is the way to go, but as above poster said rules come into play.

No I am making that out of 3 inch stainless mandrel bent pieces . I am currently running a stock 4430 with modifications to mount the turbo just wondering if there was one out there that would work better thanks for the advice
