4-2-1 Header Vs 4-1

[Avalanche419]

Which one is better? I read somewhere that the 4-2-1 is going to give the car more low end power and the 4-1 is going to give more high end to mid range power....I need the low end power sense i have the automatic, but is it that noticeable of a difference between the 4-1 and 4-2-1???? The 4-1 is cheaper, and thats why i ask...If needs be I'll save for the 4-2-1....Which one is going to be better???

Go buy the 4-2-1 megan racing, or pacecetter....I have no experience with the ebay ones that are dirt cheap...but I'm pretty sure they have their issues..

If this was your full race car and you were only driving at mostly wide open throttle and high rpms all day I'd say get the 4-1

Driggs has an awesome explanation if you keep searching.

I suggest you buy the 4-2-1 header because, it gives your exhaust a better scavenging effect which will get the gas out much better at lower rpm's.

You can get the 4-1 since it's cheaper. I had one on my old GS, I noticed a difference in low end power almost immediately (and I was auto too). No need to spend extra dough.

Be careful on E-bay. Most are 4-1 headers, even thought they state 4-2-1 headers (found out through experience Multiple send-backs).

Also, speaking from experience, if you are going to go with a 4-1 off ebay, not all the ads are accurate. I didn't want one of those where the collector slid inside the downpipe and was just held together with two bolts, I wanted mine to be bolted together with a flange and gasket.

Some ads showed a picture of a ceramic coated header with a flanged connection, but the first one I ordered was just another cheap kind and I had to fight to get them to take it back and refund me.

SO the 4-1 Will BAsically act the same as the 4-2-1??? It won't be that noticeable of a difference between the two??? Are you saying that I should also look for a header somewhere else besides ebay?

Would something like the above link work....I'm lookin at the top 4-2-1 on the page...It says the gaskets are built on it...Is that what would work well?

Those look good to me! I would have rather gotten one of those than the one I have actually. That's a pretty cheap price too, cheaper than my 4-1 was on ebay.
