FP Cast Race Manifold for the 4G63
Meh. Most don't even use washers on the manifold and a lot remove the studs for bolts, myself included. The lock nuts can be re-used a few times. This shouldn't be an issue.

Psssshhh, No...That's the problem. Would be nice to get a rough idea what people will see. Back to back dynos on a stock vs FP one. We understand environments, etc...blah blah blah are different. Rough estimate of 10-25whp would be nice to see just bolting it on. Then a tune estimate of 30-40whp. I'm just throwing out numbers and so can the manufacturer and we can't hold it against them.
I guess it's better to just get more personal numbers once we buy them and do a review. We can all agree to disagree B@#$%s!
