Should I replace my stock collector with a header while I have my lower intake manifold off seeing as how everything is so open right now? What will be different in regards to performance? Will I notice a big difference if I stick a header on and put the pineapple sleeves in?

 

My thoughts on Pineapple...

if the rx8 sleeves come with them why not just put those in the fc's and be done with it?

 

what do you mean by this

 

what I am asking is are the rx8 sleves the same in diamter and do they connect the same? if so why not just use the rx8 sleeves in the fc?

 

I just installed a set of the PR inserts. last week in my '86 na.

No huge power gains, but I can definitly feel a smoother power band from about 5k-7.5k rpm.

Couldn't tell you about the header...

Maybe you could tell me when you get yours in?
