im lookin to buy a exhaust header but not sure which is better, 4-2 or a 4-2-1.thanx

 

i think you meant 4-1 when you said 4-2. anyways go with 4-1 if you are looking for the power band to be up there.

 

almost all 4-1 hang dangerously low..

 

4-2-1=low end power 4-1=high end power. "better" is an impossible statement. it depends how you want to build your motor

 

i agree with buyimports2. the 4-2-1 is better for low to mid end power. I have the dc 4-2-1, and love them

 

yea i ment 4-1, not 4-2. but anyways thanx alot guys. the setup is going to be just till i get all my turbo put altogether

 

I saw a back-to-back dyno of a dc 4-2-1 header and 1 dc 4-1 header. Both graphs were virtually the same. I say whatever you can get for a good price. A better question would be "what is the best header for my ________ application." When you are speaking in general terms like this it really is hard to give you a correct answer

 

SEARCH, this topics has been covered a ton times.

 

No way, he meant 4-2 then dual exhaust haha. Sorry, I've gone without sleep for over 2 days. Shoot me.
