***Solution: BBP Header, Ebay Hi-Flow Cat., OBX Racing Muffler for right now until I order RSR Catback.
Updated Problem: Came on with check engine light for secondary 02 sensor code for malfuctioning something not sure bank 1 sensor 2 and air fuel monitoring system

Re: Check Engine Light
1st thing replace o2 sencer 2nd clear code 3rd drive car if code comes back you might need a spacer on the o2 in the cat .You did say it was a high flow one right some times the o2 will sit to low and because the cat can flow more it has an effect on the o2 .

Re: Check Engine Light
The reason why you have a cel is because of the high flow cat. even if you replace your o2 sensor which is doing its job right, you will still get a cel. The cel for the 2nd 02 sensor will not hurt perfomance or any thing in the car. you can learn to live with it or i think they have something that tricks the ecu dont know about hondas.

Re: Check Engine Light
+1 on the spacer or look into an 02 simulator. Not sure if they have those things for Hondas but I have used them on alot of GM vehicles from a company called Casper Electronics.

Re: Check Engine Light
It is mostikely the secondary O2 sensor code... which is on the cat. Any time is reads less oxygen, it wil toss a CEL. There are a few ways to fix that.
1. is obviously put a stock cat back on
2. place an O2 anti-foul plug... which is the same as what referred to above as "spacer"
3. get an O2 simulator
4. leave the sensor out (do NOT unplug), if you unplug it, the circuit will be incomplete therefore the same O2 CEL code will pop up.
If you decide to use a simulator, I have one for sale.... $20 pick-up

Re: Check Engine Light
well... im getting this same problem...
i but a tanabe cat back on my 97 accord, only i had trouble getting the cat off, so i took it down to the mechanics shop and they loosened the bolts but left them on...
im wondering if the torch they used heated the O2 sensor and broke it? or broke my cat? because at the same time, my CEL came one...
should i replace my cat? or my O2 sensor?

Re: Check Engine Light
^that will be ideal on a heavily modified car running a wideband. In his case, he would have to switch to OBD1.... meaning that he has to get a conversion harness, get an OBD1 ECU, get the ECU socketed, then get it chipped....... that is just too much time and money involved.
IMO, I would never delete or have a tuner delete "all" O2 codes on a motor running without a wideband. In his case, if he takes the OBD1 conversion route, then the secondary O2 sensor would be unmonitored anyway...... even without getting it chipped.
It's the mostlikely your sensor.... unless they internally and physically tampered with your cat. Hopefully, the shop did not use torch to loosen the sensor itself.....

Re: Check Engine Light
New problem update.....................
New Code--- Vehicle speed sensor
Now my speedometer isnt working..... i notice it when i went to go text drive it down the street after a couple mineuets of driving it... its not working at all so i dont kow how fast im going.....
I jacked the car up and pulled the vehicle speed sensor out of tranny and stuck a drill to it so i could spin it, well no luck didnt move my speedometer. So went to advance auto parts priced one at 211. something dollars lol i said fuck no,
So i pulled one off a tranny i had that i knew was good and did the same thing put a drill do it , still didnt work so im screwwed. i dont know what to do used a muiltimeter on the sensore looks to me as if its not getting any signel now... any response to that guys?
