hey guys, ive heard changing to a ctr intake cam can provide a nice hp gain, i know it wont be anything extreme, but i am on a tight budget and trying to make the most of my money. would it be worth it for me to just get the intake w/out the exhaust? i am currently running a b18c1 with k&n filter, skunk2 intake manifold, jdm type r headers, test pipe, and bpipe. anyone have experience with a similar setup? p.s. already searched....
