hello,
new to my 98 cobra ( and 4V's in general)

looking for some headers : this is to be a road-course racing car.

'98 b-headed engine, which will remain naturally aspirated.
i can forsee p/p'ing the heads, and valve/cam jobs sometime next year.
also planning on a full MM maximum grip box, including the k-member.

***looking to maximize area under the hp & torque curves, not peak numbers.***

(1) are LTs what i want???
(i don't want any ground clearance issues, either)
would mid lengths be better for road racing?
or, (perish the thought) shorties??

(2) if LT's are the answer, 1 5/8" or 1 3/4"??

(3) what size for the rest of the exhaust system, 2.5" or 3"??

(4) x or h pipe? (the throatier the sound, the better, but again, i want to focus on area UNDER the dyno curve, with road racing in mind)

going with an off-road mid-pipe, since i live in a state which doesn't perform emissions testing (or even vehicle inspections for that matter)

thanks,
doc

32v's love to rev >high rev cams and long tube all the way I scored mine off fle-bay for $165.00 (new) plus shipping / mine are 15/8 . they are not coated headers but I plan on powder coating them while my car is down for up-grades ( I'm building the trans right now) > cams will cost you $1200.00 new plus springs and the install if you have to pay someone to do it .

Yeah, the 4v engines benefit best from a set of long tubes. If you want some great quality headers, hit up Kooks. But you are going to pay a little for them. The power difference between an X and H pipe isn't really drastic. If you want a raspier tone, go with an X.
