Need input from boosted h22's downpipe, cat-back size to power ratio
Any of you that have tuboed H22 plz help me.
Would a 4 inch downpipe w/ 3 inch cat-back produce more whp than similar setup but with a 3 or even a 3.5 downpipe?
Is back pressure still a consern with turbo's?
Thx in advanced for the help.

I got your PM, here is a pic of what I did. 3" dump right out the bumper, with cutout going to stock exhaust. Here is a link. https://honda-tech.com/zerothread?id=1852378
The bigger the better with turbo exhaust, if you have the space do a 4" from turbo back.
