LPPs shorties fit I have them on my 09. I'm switching to pacesetter lts and hi flow cats when I get home on leave. No check engine lights or warranty issues with the shorties but I dont know how much of a gain you would get. I liked them but I want the lts. My opinion is go for the lts to start.

slightly noticed some improvements sounds was a lil better and they look good. I could average 21.7 mph on the highway at 70 and I had the 91 octane diablosport tune. It just wasnt enough for me.
