I'm getting a test pipe along with the custom 2.5" mandrel bent piping from kteller8 and I'm wondering if it provides much more hp and flow than a high flow CAT. I live in FL so I don't have to worry about emissions. I'm worried that if I get the test pipe, that in the future when I decide I want to sell my lude, I won't be able to due to the illegal test pipe. With exhaust it's all about better flow and the test pipe would definately provide that....but how much better than a high flow CAT? thanks

 

The test pipe will definitely flow more air than a high flow cat. If emissions aren't an issue in your area i say go with a test pipe.

 

I was talking to the owner of a local exhaust shop. He said that a High Flow cat was just the legal way of having test pipe performance. He said it would make no difference.

 

how the heck will you stop the engine light from staying on from the O2 sensor?

 

o2 sensor simulator

 

OBD1...

 

****...will I really have to put out more money to keep the engine light from coming on...that sucks. I don't know if I want to test pipe now....just to keep from the hassle of f*ckin with the o2 sensor. Is it hard or easy?

 

No, you have a 4th gen correct?

 

Correct, 4th gen H23

 

if i'm correct the o2 senser is in the header, not the cat.

 

as long as you don't have a 96 then you have OBD1 and you are good. If you do have a 96 then all you need is a OBD2 to OBD1 conversion harness. Or I thought there was a how to either here or on Superhonda.com.

Peace

 

what kind of nominal hp differences are we talking between a test pipe and hi-flow cat? assuming appropriate airflow is supplied (CAI, header, exhaust have all been added)

 

That's good to hear. I already ordered my setup from Kteller and just have to send him the money.

Well, you would also need an OBDI ecu to go with the conversion harness If you have OBDII and want to run a test pipe CEL free, just do the OBDII "workaround": http://www.ntpog.org/mods/fifth-afc/ecu.shtml

 

So to propagate my laziness , does someone know how much would a full OBDII to OBDI system would cost? It seems to be a good investment. Thanks

doesnt work forever..
the work around works for about 8 months... then the CEL appears in full force and you can not reset to get rid of it..

Woah, that is the first I've heard that
