Hello everyone, I'm pretty new here and over the last few days I have been scanning over all the great info. I do have one question though, I'm planning to buy some headers in the near future and was wondering if the Stillen Stainless Steel headers were legal in MD, and if not could someone point me in the right direction for some quality headers.

 

Not to hijack the thread, but this raises a good question: If a part is labled "for off-road use only", even if it's a Nismo item (perhaps R-Tune stuff), is it going to void your G's warranty?

Can't recall if their headers are R-tune or S-tune.

 

IMO they shouldn't be illegal. In the IS forums headers are illegal because they remove 2 cats. The G's cats aren't built onto the headers so I don't see why they would be illegal as long as you have the cats on. Does anyone know for sure?
