[RICK LAKE]

Jcooper J Like others have said, a business road trip to corp headquarters is needed. ERA makes quiet side pipes for street cars. Alot depends on the compression and camshaft profile for how loud the car is. If you run a wide profile tire, most have a 40 or 35 series side wall and no clearance. Have seen the starburst wheel on a street car with 428 power and looks nice. Car is a real cruiser. Car has taller tires in a 70 or 78 series in 15" this will give you ground clearance. I don't know if ERA has looked in Oval pipe for th exhaust but this will give you another 1/2" more of clearance. As others have said problem is size of pipe needed for motor to need. 2" is fine for a SB motor in duals. Anything over 400 cubie's needs min of 2.25 or better 2.50" pipe. It's a trade off. Good Luck, Come to Carlisle and check out the cars. Nice write off next 4/15/13 and by this time there will be a car in your garage. Rick L. Ps either motor will move this car along with ease. With a SB motor, wide ratio 5 speed with a 2.80-2.60 first gear and overdrive with a 3.31 to 3.54 ratio in the rearend. Rearend depends on tire size and torque band of the motor. BB motor with good torque is any choice you want. I have a mild motor with 3.31 gears and 6 spd trans with overdrive. I am going to a lower gear for next motor of 3.07 in the Jag rearend. Other side note is powersteering for the car. Good luck , have a safe trip. Rick
