I

 

I have a Berk like many others. Overall their all pretty much the same thing. A piece of pipe.
Your poll does not work...

 

Next time don't start the same thread 3 times.

 

New here boss... My bad

 

Any of those pipes will most likely throw a CEL. You will most likely have to do the O2 sensor modification first before clearing it.

 

Yes you will throw codes with any of those pipes. Your going to have to do the anti-fouler modification to prevent the CEL.

I'm running the anti-foulers now on my T1R and I have yet to have a CEL.

 

the berk pipe does not throw a code if you screw in the O2 sensor correctly. Sounds simple, right? I had mine on for over 7000 miles no problem. had a CEL come on for a short time but I attribute that to me not tightening the gas cap enough as it went away after the next fill up.

BTW---Invidia + berk test pipe is CRAZY loud.

 

I initially ran the berk test pipe with no cel on my invidia for about 3000 miles. When I changed my catback to the B&B, I got a cel. So to remedy my problem I just added the anti-foulers to the berk and the cel was gone.

Any of the above mentioned pipes will work out fine. Afterall, its just a piece of pipe with a flange on either end.

 

hahah, thats why I had to get rid of my invidia. I got 2 letters in my mailbox the first week I had that setup on.

 

10k miles, no CEL on berk
