Grand-am cup cam fuel milage
I took a trip from Sterling VA to my home town in Ohio this weakend. With the exception of passing twice the car managed 18 mpg. I made a true duel 3" exhaust with two random tech cats and dumping out both sides (it's pretty loud) the car has responded very well with some noticable bottom end and very free flowing up top (open headers sound about the same) Hope to see a few more people give this a try, I love my setup for all GM stuff up top.The car has been a best of 11.56@123.24mph and 7.44@96.89 1.76 60' stock 10bolt with 4.56 gears hoosier qtp 27" tall tires 7100 rpms through the traps.
