Hi all, I've been searching the threads on here about bore size and back pressure but can't seem to find the answer I'm looking for.
I've bought a 888 coupe back box and want to put it on my z18xe coupe. I know the bore of the exhaust is bigger than standard, but my question is this.
If I put in a non silenced centre section (remus, sportex cybox etc.) will that create enough pressure in the system to counteract the loss of back pressure (if any) by fitting the 888 back box?
Hope someone can help.
