I've got a JRSC with a soon to be Bisimoto header
Question is I currently have a 5Zigen 2.25 midpipe. Should I upgrade to a 2.5?
Would it make that much of a difference? Since I'm spending so much coin on the header, I don't want to have my midpipe rob anything from it.

Thanks

for sohc motor stay 2.25 you should be fine..

i had a JRSC on my 98 coupe..similar to ur setup w/ 2 1/4" piping and a DC header s..its going to be loud

in my case i had to eventually throw on a resonator..if i had to do it again i would have used a 4" round magnaflow resonator

id go with 2.5....i was using 2.5 with boltons and i felt a difference from 2.25...since your supercharged i would think you would benefit from bigger piping

i thought the bisimoto header was tuned specifically for n/a apps, wouldn't this be detrimental on a f/i car?

As far as I know since it has a 2.5 outlet and equal length tubes, this header would be awesome for both na and sc applications.
But if you find anything out about this let me know.
