Going to true dauls, but what size exhaust?
With the mods in my sig, what size exhaust should I go with? I will eventually be going to a larger cam and ported heads. But that probably will have to wait till next year. Would 2.5in. be enough or should I go to the 3in.?
Thanks
Aaron

No cats and the X pipe will be a pieced together one that is out of Summit. The header collectors are 3in. so I'll probably just do 3in. x pipe into 3in. pipes. Im just concerned about losing low end tq.

When I dynoed mine before and after headders and !cat, My torque just increased more in the mid range. Instead of a flat curve it was "humped" in the middle, but I didn't lose any torque. A tune has then fixed that and now it's flat again. I am running a y pipe though. Maybe this will help.
