i have a 06 LS hatch, Manual, aftermarket muffler and SRI, just passed 10k miles and ive had it since May 06, usually get like 260 from the tank at most, i dont think these 2 little mods should affect mileage that bad....

never broke 29 on 100% highway??? jeez i did all highway to the shore once and its an hr drive and the needle barely moved

[pqaveo]

and the needle barely moved

Did you start with a full tank? It takes a lot more to move the needle from full to 3/4 full than it does to move it from 1/4 full to empty.

yea

wow that's some bad mileage. Do you sit in traffic a lot or let your car warm up for 10 minutes before you leave anywhere? The worst mpg I ever got was 17mpg and that was only track driving at Willow Springs where I neared redline the whole time.

no traffic... my trips are usually between 5 and 15 miles, with very few stops. I usually don't sit and let the car warm up, because it seems like thats a waste of gas considering that would be giving me 0mpg.
