Hey bro, i just saw your post about the quad exhaust and i saw what you did with your rear. I bought a zhp not too long ago and i want to keep it looking original and not like an M3. So the thing i really want to do is the quad exaust, just the way you have it. If possible can you explain to me how it was done so i can tell the mechanic. And another thing i wanted to ask you was how much is your car lowered and how did you lower it. I hope im not a hassle but i would really appreciate your help. Thanks alot.
