I have a B&B Turbo back exhaust and it throws a CEL. I read that the Ultimate Racing test pipe is gauranteed not to throw a CEL. Wil the Ultimate Racing test pipe flanges fit up to the B&B down pipe and B&B cat back? Thankis for the help

 

i think everyone pretty much says it will bolt to whatever.....if you really want to know the truth...email or phone them.

 

I have the B&B turboback with the UR test pipe, they fit fine
