Since i put my exhaust on a few months ago whenever its idleing the exhaust will studder every couple of seconds. Its like a cough. Maybe some air getting stuck somewhere?? Is this a big problem or normal for aftermarket exhausts. Thanks for any help.

 

sounds like you have an exhaust leak...double check all your braces...if you plan on keeping that exhaust take it to an exhaust shop and have them weld it solid

 

Thanks for the info. Also will this hurt the engine at all?

 

No.
