OK, this is REALLY bothering me. I have a TB exhaust, no cat, the BR one with the 02 Bung. My 1st exhaust did not clear the check engine light, got another BR, it went on almost immediately and every time I reset it it goes on by the end of my Driveway.


Not placing any blame BUT I WANT A PRDUCT THAT WILL CLEAR THE 2ND O2 SENSOR IT IS FU-CKING ANNOYING. I also want a guarantee.


Anyone???



today I fixed the problem, tuned out My Joe P MBC had lost its set screw leading to a nasty boost leak as well as ONLY 12 F U C K I N G PSI no clue, bought a Hallman and set it to 21, Check engine light shut off, the end....


SO FING HAPPY OMG!!!!!!!!!!!!!!!!!!!!!!!!!! NO CHECK ENGINE LIGHT, NO CAT, TAKE THAT MOTHER NATURE!!!!!!!!!!!!!!!!!!!!!!!

 

**** dude I got the same issue! I am willing to pay just someone provide me with somthing to get rid of that CELL!

 

gonna love them cels.my tb br exhaust is coming soon.i'll be in the same boat probably

 

Let me know what code you have and i will tell you how to fix it.Another thing is if you clear it and it comes back on by the end of your driveway,then most likely it is not the o2 sensor bung,as the o2 sensor,unless it's damaged takes what is called 2 trip detection,and clearing your code and driving to end of driveway does not qualify for 2 trips

I have the buscher 3" tb and have had only 1 SES lite,p0138,o2 voltage too low,and after monitering it found a quick fix for it.And midwestmonster is also right as I had the UR cat delete pipe before the buscher 3" tb and it also worked well as I never got a
SES and did also moniter the o2 sensor readings and they stayed right around 0.750 volts,just like they would with a good working cat converter.Total different design though.

 

I have the RNR turbo back no cat and also replaces stock 02 housing . I have a cell also is there anyone that can tell me what the code is for free?

 

Exageration but it is quite quick. like less then 100 miles, on every day that is for sure......

 

I have the Buschur turbo back exhaust and after a month of having it I am getting a P0420 code. Took it up to Autozone and they told me the code. Not sure what to do, maybe something is lose by the hi flow cat?

 

call BR, they are excellent when it comes to customer service.
I had the same issue, and I was given a fix. I run the TB w/ the HFC. I no longer have a CEL

 

I believe that p0420 is cat efficency below threshold,which means
that your high flow cat is not doing much as the post cat o2 sensor reading almost the same as pre cat o2 sensor,hence this code.Could be from running so ******* rich the cat cant possibly keep up with all the fuel going through it.Do you have any type of fuel management?? ie:safc,flash of any kind?? my guess is no??

 

OK, I guess the squeeky wheel gets the oil...


Today I start me car, after WEEKS of having a check engine light, it is now off. Drove the car around ALL day, and now it is off, hopefully for good, BUT I doubt it.


ANY HELP PLEAZE!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!? !?!?!?

 

My UR test pipe is for sale - $50 plus ship. I ran it for a few months with no CEL. I then went to a high flow cat and did get a CEL for 2 days, but it went away. ( I verified the code was an inefficent CAT)
Bottom line is that the UR test pipe tricks the O2 better than a high flow CAT!

 

werd!

 

CALL BUSCHER they have a fix!!!
