Hey all I finally got around to getting my Nismo exhaust and Strup headers. As soon as I was driving off from the shop, I notice some pretty annoying rattle from underneath me. It doesn't rattle when idling, only when accelerating. Has anyone has problems like this, or is it supposed to happen with this combo? I've had headers and exhaust on other cars, but never ran into the rattle. Should I take it back to the shop and complain?

 

no reattles here

 

stock test pipe?

 

Yea, stock cats, until i get the Kinetix HFC's in like a week or so.

 

hmm i get a rattle due to my testpipes....

 

Let us know if that issue goes away. If not then something about the header.

 

If it feels like its underneath you, it could be rattling against the chassis cross brace / M-brace... my true dual did that...

 

Well, I took it back this morning. They claimed the flex part on the y-pipe had to be heated up and slightly bent. There is still a lil rattle once & a while, but for the most part is fixed.

 

so the problem is from your Nismo exhaust? glad it works out.
