Ok.....I am giving in and getting a tune for my '12 GT...I may go catless while I am at it. I currently have a Borla Atak catback. How hard is it to install the cat delete pipes without a lift? I am only going with the delete pipes as I want to keep the Borla system as a whole. I also briefly chatted with the emissions testing guy as long as the computer test passes they don't fuss too much, I am in MD btw. Thanks
