Yes you have to remove the tail in order to get the muffler clamps in place. Yes I installed a PC3USB and I used the Graves map. It is much throatier than stock but not loud. I think it is perfect. Runs awesome without the cat. Runs a little cooler which is what I was hoping it would do. Good luck and feel free if you have any more questions. Did you get the titanium or carbon fiber?shmalhit said:Did you have to remove the tail? Did you install a pc3usb? If so, which map did you use? I just picked up my akra slips and pc3 from fedex....I'm gonna install them in a couple of hours. Is it loud? How does it run without the cat? Thanks
Looks awesome!!! Lets see some pics in the daylight.shmalhit said:ok, finally got'em on. Took me about 1 hour and a half...the pc3 was the frustrating part having to lift my full tank of gas! Did'nt gut the cat though...seems fine to me.....good throaty sound and way more responsive.
