Also, the oil return pipe DOES NOT fit in it's original position, I had to to bend it and not use 1 of the bolts that mounts from the center. I will confirm if it's still rubbing the headers tomorrow as I am super exhausted... Also, you have to slightly reshape the heat shields around the exhaust area and control arm. The 3.5" exit is super close to the tunnel but it can work. I will be connecting my custom Section 1 to the OEM X-pipe Thursday (waiting on some exhaust parts). I will be adding 2 AR25 resonators to it to kill off all the rasp that it will have and to quite it down as well. I will post pictures once that is complete. Feel free to ask questions as I'm sure I left some stuff out. Cheers
A big no no for a street car from my POV
