Got my Titanium black series yesterday and couldn't wait to get it on! Had a buddy come over today and we busted it out in about 2 hours. We ran into some road blocks and not all the instructions were great but we worked our way through it and damn does she purr now! I did the obligatory start-up without any pipe and it sounded BA but would be obnoxious FAST, anyways got the pipe on and everything back in place (i think) and took it for a spin. Buddy asked for me to do a fly-by and he said it sounds beautiful! Sounds deep and growly till about 6k and then its pure F1 car till 15k. Definitely recommend!
