i cant remember which designed 4-2-1 or 4-1 is for more high end torque, both are one piece design and for daily drive basis, which one is more suitable for street drive?thanks

 

4-2-1 is more suitable for street drive. 4-1 makes all its power up high.

 

thanks dude. u the man

 

Neither does much on a SOHC or DOHC tho. Just in case you're thinking of buying one. I did, and it's a big waste, besides the temporary (hella expensive0 bling factor until my pieced together turbo kit is installed.

yea i know it will not do any performance gain .but my stock header is cracked. thats why i am looking to buy one.

 

get a $65 ebay one then. It really does do give you performance gains, just not enough to warrant spending the $$ it costs. I know multiple people that have the egay header and it looks nice and works fine, no cracks/leaks. That's probably one of the few things I'd suggest people buy from ebay

 

You are in So Cal, hit up the So Cal marketplace for a used stock one. I would much rather spend 30-60 then to use the cracked one as an excuse to spend 300+ ya know?

 

new Egay header FTW

 

I run a Ebay 2.5 outlet 4-2-1 Header on GSR until I boost it. 4-2-1 two piece and also comes with gaskets. Not a bad deal for 65 dollars.

 

get an edelbrock header!

$100+ for a quality header

 

an ebay header is just goin to crack eventually. id find a stock one.

 

Unless you've had personal experience with the ebay headers, I wouldn't speak up. They've been proven to be quite reliable.

 

ahh here we go again. friends of mine do have experiance with them. and usually bad ones. im not sayin dont buy one but w/e. i have a dcsport header and im pretty happy with it. all im sayin is id go for a used stock mani before an ebay header.

uhhhh , I have experience with them and it cost me 120$ of labor for nothing becuase its had exhaust leaks around the head.... ebay header

 

Get a megan header. And modify the collector to a 2.5" pipe. You'll have a bangin' DIY header.

Are you serious. Maybe on a stock motor it might not make a huge change, but it will help your power. If you start to build the motor a 4-2-1 or 4-1 are going to be the best header style you can go with. That why all custom headers are 4-2-1 or 4-1 design. On d-series it wont matter what you do short of a turbo set up. On a b series though your results will be alot diffrent.

 

get a tri-y 4-2-1. best of both worlds.

 

i like the 4-1
