LM question ok, installed my loudmouth about a week and a half ago and i noticed my gas milage has gone down dramatically, do i need to do something to my computer or is this normal? i was expecting some loss but this seems like more than normal! thnx
a slight decrease is expected untill the computer relearns, but that should only take a couple start-ups, 200 miles at most
are you sure your not flooring it more because of the sound, that would cause a gas milage decrease
is there anything else you did, and did you put it on yourself?

well of course i took it out after-words and wanted to here it, and yes i did put it on myself, but i did it with a fellow f-body owner and former mechanic who also has the same exhaust so im sure its set up correctly. the thing about it is, im in the Marine Corps. and i did it on base at the hobby shop and i live on base so its not that far of a drive anywhere for me! He had mentioned pulling a wire or something i dont remeber, to resert the computer.
You're probably putting your foot into it more, just because you want to hear the new sound, I did the same thing The first week I had my exhaust I lost about 2 mpg.
Give it week for you to get used to the sound, and it'll likely go back to what it was.
If you really want to reset the computer, disconnect the negative battery cable, be aware the car may idle funny till the computer relearns all the idle settings, if you want the complete process for resetting the computer, search for the term "idle relearn"

After I installed my TSP Rumbler my mileage went down a little bit. But I attributed that to I was in the gas I a little more, cause I liked the sound. After A couple of weeks it kinda wore off and my mileage got better than before the exhausty by 2 mpg.

Yeah, the reason your gas mileage is staring to suck now is due to the new syndrome in your right foot called lead foot syndrome, its non treatable and you will probably have it for the rest of your life. I know I got it when I got my LM exhaust.
