ok so i really ddint believe that putting on a free'r flowing exhaust would help with getting better gas mialege.. but it did. i am truly astonished, with my truck all stock on the street i got high 15mpg to 16.5 on a great tank being very ez on it i ws lucky if i saw 17. and on the freeway i got between 16.5-18mpg depending on how fast i was goin. well now with the gibson catback on the streets i get 16.5-17.5mpg and on the freeway i now get 17.5-20mpg its very erratic on the freeway depending on hills, traffic and speed but in any event both street and highway MPG have inproved. and it was a welcome change. not to mention the boost in power and the fact my truck makes some noise now..


now to get a tuner...

What all you put on? size of pipe?? dualies?? muffler??

 

does it sound alright? i've never thought that V6 exhaust sounds good...

 

well its the gibson single swept side. it looks to be 2.5 and its just whatever muffler gibson uses with thier kit.

i think it sounds good, its no V8 by anymeans but it definatly doesnt sound anything like a 4cly doesnt have that Waaaaam sound. it just has a little bass and sounds "smooth". on the freeway at like 80 it does start to get a slight droan but only if you have the windows up and no raido.

heres a video of i
and it compars stock to the gibson to the gibson with the muffler flipped around backwards to the way they send it. so the word gibson reads opposing the exhaust flow.
