I have a chance to buy locally a Larini GT2 6" side exit exhuast and a Larini decat. I have a 2009 Elise NA, and from what I see, people who run that exhaust are usually Exiges or SC models. As far as fitment goes, from what I've been searching, it should fit no problem, but should I have any concerns running this setup on an NA car? Is there a reason NA Elises don't go for this exhaust? Thank you for your help!!!
