what is a realilistic horse power loss using a 2.36''street legal exhaust system compaired to a 3''? im gonna be running 15-20psi on a b-series

 

Why can't you run the 3"? I think the 2.36 would cause a noticable loss, especially with that much boost.

 

Well, using the 1sq. inch/60 flywheel hp, the 2.36 becomes inefficient at 207whp (237 Flywheel).

 

its mostly because this is my daily driver and I dont have a motor that will pass smog. so I cant afford to be getting pulled over by san diego's finest all the time. but ya I do want to get the max power out of my set up. So if using a smaller exhaust isent gonna be hurting my set up that much than that is ok.im just trying find out how much of a loss im looking at
