Well, i bought this exhaust from someone on the forum, and I must say I'm in love with it. Install was very easy, everything lined up, and no rattle whatsoever from the cross member (common issue people have had with ARK).
Installation:
Like I said, fairly straight forward, just hand tighten everything first, then jack up the X pipe and start tightening bolts from the Cats towards the muffler. I have about 3/4 inch of clearance.
Sound:
I like it a lot. Could be a little louder, however i like LOUD. Sounds great though, and I've gotten a lot of positive comments on it.
Looks:
By far my favorite aspect of this exhaust is how bada$$ it looks. Also, alignment was PERFECT. look for yourself
Performance:
Probably all placebo, car feels like its going faster only because it sounds so much nicer. Will have it dyno'd and tuned soon.
I apologize for the horrifc quality (i used a phone for all of this). I don't own a camera, however for some reason my GF has like a $400 one i bought here but never seems to be around when i need car stuff....
