I have the dc sports 4-2-1 header part number AHS6507 i paid 300 canadian for it, but people are saying 4-1 is better and the one i have is pretty much useless...can someone help me?

 

Dear god man. Search for header reviews, tests, and such. There are so many angles and issues to address....

 

i have a DC 4-2-1.. i love it

 

How high is your redline?

 

Well basically (from what i heard and personal experience) the difference between 4-2-1 exhaust manifolds and 4-1 are that 4-2-1 provide power throughout the whole powerband while 4-1 are best felt close to redline. Personally i have a 4-2-1 and i am very pleased with it.

 

my red line is 8200

 

Personally i would get rid of it. I have a DC 4-1 and I dont care for it. With a red line of 8k you will want a header that will give you the most power up top. Remember most things CARB legal that you get for your car wont give you much power.

P.S. Don't buy into the thoughts that 4-1= top end and 4-2-1= low end, their is so much more to it than that such as stepped headers and anti reversion chambers. Try reading up on it, you will learn some cool ish.
