Default Will open side pipes run cooler?
Hi:

In my never-ending quest to reduce engine compartment heat in SPC 123, I am considering opening up my side pipes. I have been running the H-pipes out the rear, but think that opening the side pipes should make the exhaust manifolds run cooler because of reduced back pressure. At least initially, I would just leave the H-pipes in place until it's convenient to remove them. On the other hand, could the manifolds run hotter owing to increased exhaust flow?

Opinions, advice? All ideas welcome ...

Cheers!
