Second'ed on the exhaust, what are the 2 coupes
running? I definitely picked up a few ponies
switching
from Scorpion to a full turbo-back 3". I've run a
stock chip in my 3B coupe, and it is only marginally
faster than the old 7A. IA 3+ with Scorpion made it
interesting. The exhaust makes it frightening!
