Before anyone asks, yes I know it will fit.

Anyone that owns a Se or running a Se in other than a Se 1st gen. Have you run a S5 stock manifold or a S4 or S5 header. And if so did you compare performance versus the stock Se manifold or the Smaller Se header?

 

Yes

 

Oh thanks, that's all I need to know.

 

i ran the fc collected header/presilencer on my SE. it ran pretty well, i liked the 2.5" all the way back. i did the whole exhaust at once, so of course my butt dyno noticed a world of difference.. though the presilencer did scrape over speed humps.. header makes the piping drop below frame rails.. other than that i was happy with it.

found a pic that i took a while back.. if i remember it was about 1 to 1.5" below the frame rail.. pic is sorta misleading..

 

Thanks for the info Unsupa. Still would like to see if there is hard data on the performance difference between the Se design and the Fc design.
