Meisterschaft Exhaust on GTM TT?

Boosted Performance

I don't get this mith that a dual 2.5" exhaust sytem is too small for 650whp+.

Cross sectional area of:

3.0" single exhaust is 7.0" squared (supra guys makig up to 700whp single turbo)
3.5" single exhaust is 9.6" squared (supra guys making up to 1000whp single turbo)
2.5" dual exhaust is 9.8" squared (370z has difficulty making 550whp on a stock block)?????

Now, the one thing that needs to be considered are the mufflers. If they are baffled inside, then you can run a 6" exhaust and it will still be restrictive. So straight through exhaust mufflers will not hinder performance as much as it is suggested around here.

I had a customer with a BP kit on a (built block) 350z with a dual 2.5" Borla exhaust. When he removed the rear muffler he gained 100whp because the muffler was severely baffled, and was a massive restriction to flow....the piping was just fine.
