ok let's say we have a regular V6 2.5 motor...what are the most restrictive parts in order from most to least restrictive? assuming it has a basic intake, and a trubendz cat back exhaust.
MAF...TB...UIM...LIM...intake ports on heads...exhaust ports on heads...exhaust manifolds...y-pipe...cat section...another part of your choice
by restrictive i mean by "all motor" standards...not boosted or anything like that cause then it all changes lol. also, what would be the most restrictive parts on an SVT motor...since the UIM/LIM/TB/heads are different.
