what Test pipe should i get to go with HKS Hi-power ? and where to get it ?

i heard there is a 50/50 chance you get a cel with TP , is it easy to fix ?

 

i know jshimer23 has a test pipe on his HKS but i forget which one. he can give you all the details. he will chime in soon

 

If you do it right you will not throw a CEL. I never did for 4 years.

 

i hear good things about berk. but i think you need to make sure the TP diameter is equal to that of your exhaust where they connect. so if you have a 63mm exhaust, get the 63mm TP

 

I had berk with hks before, sounded great.

 

this is quote Bryan at berk "Yes, it will fit on all 00-07 S2K's. But on the 06-07's you will most likely get a CEL. The 06-07 DBW cars are VERY finicky when it comes to test pipes."

i have a 2008, in case i throw cel , anyway to fix it ?

 

Yes.

Berk has a mechanical o2 simulator already welded to the pipe. If that fails and throws a CEL your going to have to purchase another simulator which actually connects to the o2 sensors wires and fixes the CEL that way. I forget what its called though, I can't remember if its electric, digital or something else.

 

My Megan and the spark plug anti-foulers has worked great for me.

 

I thought it was more of just a spacer? As I understood it the issue is that the o2 sensor needs to be moved out of the direct airflow so that it doesn't catch as much of the direct soot/burn off from the engine. If you get a CEL then you screw another extension bung into the first and the o2 sensor into that one so it's even farther out of the way. I could be wrong but I am pretty sure I read that in the UTH forum.

As far as test pipes, they are just a piece of tubing to connect your header to your exhaust, there is very little difference between them so unless you have heard that they are prone to cracking/leaking then go with whatever is cheapest.

An image of how I understand it: test pipe with no fix, text pipe with welded fix, then test pipe with welded and extra fix. The gray cloudy part being the airflow.

 

I have the Berk + HKS combo and it sounds fantastic.

If you're putting a test pipe on an 06+, chances are you'll get a CEL. The built-in extension to the Berk pipe doesn't work for me, stacking an extra anti-fouler on top of that didn't work for me either. There was some thread floating around of someone trying an extension that was a long "L" shape, but I can't remember if it worked or not.

The O2 simulator Frank is talking about is another option, but there's one small thing: you can't find the damn thing because nobody makes one. I looked everywhere for an S2000 O2 sim and no luck. There were some made years ago I believe, but even then they weren't guaranteed to work. I'm not sure if they even worked on the 06+ anyway, it seems damn near impossible to trick this car, outside of a few lucky ones maybe.

Summary: Get a test pipe and enjoy it, but get a code scanner to clear out the CEL you'll be getting every week or so.
