I just put the RB midpipe on with the 02 sensor and it didn't throw a CEL. Is there something new in the 09s that allow cat removal without a CEL or will it come on eventually?

 

i think it will come on eventually just takes time but then again i have an 04 so what would i know :P

 

I've had no cat in my 08 for a good 2 months and nothing yet..

 

my CEL came on when i first put it in, a couple of months later it went off for a couple of months and now its back on

 

I guess that o2 CEL is a tricky little bastard.

 

I've had my mid pipe off and on a few times...after about 4-5 drive cycles the CEL would trip with the mid pipe installed and after I put the cat pipe back it would take a couple drive cycles to go out.

 

it will probably come on sooner or later!

 

Just got it coming home from a friends

 

See only a couple drive cycles as he said and it would come.

 

I thought I was special

 

yeah I used the spark plug fowler trick and thought I was all bad *** and then it came on after a few days.

 

I'm getting terrible chatter from the hanger. I need to find something to wrap around it and make them fix it when I pick my cat up Monday. Is this only a problem with the RB, I have no idea what to get to wrap it in

 

I had a rattling from my catback and just bent the hanger but def took some elbow grease!...haha....anything you wrap it will eventually rub off/come off
