I just installed a SRS race header( A DC knock off) on my car this weekend and I am hearing a rattle noise under my car under hard acceleraton. Anyone with race header( no cat.) havin the same problem???

 

heatshield

 

I just got my car back from the dealer and they said it was the header itself. I thought it was and exhaust leak or something. I'm not sure if the heatshield is the problem. Are you talking about the one under the chasis where the cat used to be? That is the only one I did't remove.

 

you brought your car to dealership with that header on your car? better hope they didn't red flag your car.

 

It's all good if I blow a motor it just gives me a chance to rebuild it better. Plus I know the guys who work there and I'm not worried. Now please if anyone has any good feedback I would appreciate it
