My cousins DC5 just had DC headers and catback exhaust installed by a friend. When he drives and shifts gear its seems as though the headers or exhaust are loose and tapping against something because you hear it from inside. When we checked to see if headers were tight and bolted up everything seemed fine. But when we drove it same thing. A tapping nose from what seems like a loose header comes from the engine. Any suggestions on what it is? Its getting annoying and can be heard even with his loud exhaust.

 

Could the header be hitting the front sway bar?

 

Hopefully he isn't driving it without ESMM or an ETD because that could be the header cracking.

 

yea thats what i was thinking

 

I dont think its the header hitting the sway bar from the looks of it , it clears it. I should take a pic and post;
