i'm thinking about installing headers and test pipes on my g35

but its only been 6 months since i bought this car and i purchased extended

warrenty with this for about 2k (not sure).


i know that installing aftermarket parts does not void warrenty unless it causes a problem.

so my question is do headers and test pipes likely cause any problems
to the engine?? I do not race and not a horrible driver haha

I live in Orange county, CA.

 

With my test pipes i know the dealership voided my emissions warranty.
