RE: quick question
Put on too large ofdiameter exhaust pipes & your fuel economy might even get worse.. Some think "the bigger the better" and put 3" dual exhaust on their mostlystock car, which will reduce backpressure too much.

I have a full Bassani exhaust and it made no difference at all.
The biggest thingI did that helped mileage was to bump the timing.That won't help any if you don't advance the timing from idle.

RE: quick question
greystang is correct, i had the same problem, i had to throw in a h-pipe to make up for a little compression loss. i felt the difference in power but the gas mileage slipped away a little. until i put the h-pipe in it ran like **** too
