header 1 has that funky bend at the bottom.

where as header 2 has the 4 to 1 what seems to be kind of abrupt…

header 1 looks like it may… flow better

header number 1 will probably produce better low end with the shorter runners, however 2 look slike you see better gains up top with the longer runners.

but i cant realy say much about either without seeing the collector. the collector is where the power is made.

collector for number 2 i cant find a picture of number 1

Two seems like it’d flow better.

4 into 1 produces more top end, tri y is for midrange. granted they are of same build quality you have to decide what power range you want.

i dunno i want to do a lot of auto-x this year so im thinking low end tq would be better. my eventual goal is to get to 200 RWHP NA but that probably wont happen this year due to lack of after market support right now

#1 has no merge collector.

#1 looks like a cheap OBX type ebay pile of doodie.

#2 appears to be of better quality and appears to be coated.

My vote #2.

you will never get the lo end tq you want outta the 4cyl. so you might as well try to get as much as you can up top and learn to keep your car in the power band.

header #2 for sure.

Where is the turbo flange???

#2. Long equal length primaries FTW.

whats the ID on the outlets?

Get # 2 and weld a good merge on it :tup:

2.5"

and there will be no turbo of this car, i got sick of fixing things on my other car when it was turboed which is y i have this one.

also #2 does not come coated they had that coated for their car but i want mine coated though

#2

u can always send them out to get coated once u get them if the company doesnt sell them with that option

2

#2

but

it should be stepped, and cut the “collector” off and have a real one put in its place.

so in other words neither of these lol

uhm, well yeah.

and i know you were thinking the same thing :stuck_out_tongue:

oh definitely lol. I wasn’t being a jerk. That was my opinion and just summing up your s :stuck_out_tongue:
