Hey I have a 98 jdm b181b ( compression is 9.4 vs 9.2 in US ) anyway, I have a full 2 1/4" cat back and I'm looking for some 4-2-1 headers with a 2 1/4 " collector???

Thanks Pat

 

Headers?

 

I'm looking for headers with a 2 1/4" collector ( where the down pipe connects to the cat)
Who makes one with a 4-2-1 design???

 

Where are you going to put the other headers?

 

if by that you meen what am I going to do with my curent jdm b16 polished 2 peice 4-2-1 headers with a 2" collector...I don't know yet!! I'm going to think about that when I find a set of headers with a 2 1/4" collector!

Ha ha, he's new. I got beat up for that one when I first got into cars.

But as far as what header you want, the fields wide open, go for anything with a usdm lenght and 2.25" collector. The only other option is jdm length and 2.5" collector for standard header bolt-on class and thats obviously not going to fit unless you get somet type of reducer cat/test pipe, which is kind pointless.

So, get what you want, DC is cheap in cost and has ok gains, sms, hytec, toda are the higher up's and cost more, but give better gains, especially with built engines and tuning.

Just make sure you let them know your getting one for a us cat/exhaust sized replacement. Just in case it doesn't state the flange size.

The rest is up to your choice now. And please search around, there are so many header choices and take a look at the header shootout if you want performance comparisons.

Ha ha, no, he's saying the correct word is "header". "Headers" refers to more than one headers.

Lol, that could've gone on forever if kay didn't ruin bauley's fun.

I've never heard of the b181b, maybe its a boxer style engine like the wrx has, then he would need headers (although 2 1/4" for 2 cylinders would be a little much).

I'm not aware of any off-the-shelf or typical custom header that has a 2.25" collector. All of the "USDM" bolt-on headers feature 2" collectors, and almost every JDM or custom header utilizes a 2.5" collector. I'm sure you could have something fabricated with a 2.25" collector if you wanted to, but they're definitely not otherwise easy to come by.

 

lol...Honda techs inside jokes..
