I have a couple of questions about my truck, first I gotta say I love it the power is great comfortable smooth as long as the hyway isn't torn up, I have a 2500HD crew cab short bed 4X4 and I use it to pull, I have the hypertech chip set on three and empty at 75 I get 19 pulling depends from 10 to 15, first question is a 4inch exhaust worth the money, I just have a k&n filter not the whole system ( don't want to hear it) and a friend put it on and barley any improvement, second question I have airbags but also thinking a rear sway bar any thoughts I don't want stiffer I am more concerned with body roll pulling a trailer, and does anyone know how much the engine ways, thanks for any help

Im putting a 4 inch catback on mine tomorrow, Its gotta be worth it, lower EGT's and what, also, alot of people seem to notice a diffrent in throttle response along with more turbo noise! As far as the sway bar, cant help..Enjoy:)

yes the exhaust will help greatly, these engines need to breathe. some have the kitty removed my self included, but i have the lly motor. dont know what year yours is. fill out your signiture and we all will be able to help more.

plus you gotta love the sound of the dmax

yeah they sound great. normal driving its just perfect, but you know when your into the throttle.:grd:

first off:welcome2: :welcome:
exhaust....if you leave your cat in place you dont get anything more withregards to power,you need to loose the kitty:D to lower your e.g.t.
however some say they get an ses code due to lack of backpressure. if you do then you need to block and stick it,then it could spiral out of control from there:eek: i.e. need more power:rolleyes:

you could really benefit from new sway bars,just read that someone put a set on their ride.(do a search on that).they will help you ''mucho lotto''(sorry im from mexifornia and need to learn the new language:mad: )with lateral movement while towing plus you will have yourself a cornering sportscar when not towing:p:

someone weighed a complete d-max with accessories and i think it was just under (1000 lbz:lol: :muahaha:)get it !!! i krak me up.


anyways also search this(search is a wunnerful thing,and the moderators wont have to keep tellin you "THIS TOPIC HAS BEEN COVERED SEVERAL TIMES.......:blahblah: ) so good luck with the truck and welcome again.
