jdm h22a...

I have a megan racing header with 2.25 collector mod, 2.25 crush bent piping, with rsr axle back (ex mag ) 2.36"

IF i kept the header, but a new, 2.5 mid pipe, with a 2.5 muffler.. how much power would i see?

or 2.5 mid pipe with existing rsr muffler ( i likethe quietness?)

or NEW 2.5 colelctor header, 2.5 test pipe, 2.5 mid pipe, and 2.5 muffler?


im shooting for 200WHP

 

2.5 all the way with a new header something custom like RMF
