Before this get's moved to the exhaust forum..... (you'll get the hang of it eventually - saying that I'm still never sure and this is 10 months on...)

Taking the AI off will stop the pipes going blue....or sitting every week and polishing it off... And that won't invalidate the warranty. Most dealers will take it off for you....if they can get a kit. Or know which Nissan parts fit....

The exhaust - I'm no expert. Ask the dealer if it will invalidate the warranty. But I wouldn't have thought so. I'm still grining after taking a baffle out from the stock pipes yesterday... And if I can do that (OK so my dad helped me but I told him exactly what to do..) anyone can.


Gina 03 America - Pretty stock - except the TBS wheel... 06 America - missing, presumed in bits. With it's TBS wheel... 09 America - It's very blue....
