got my g-tech back, I did a 9.70 0-60 this morning, so I beleive the exaust has helped, a little to loud but its worth it,

 

9.7 for a 3.7 v-6? Thats not half bad. I heard that the 4.7 v-8's get 0-60 in 9.8 but maybe thats just a rumor. Good luck with your truck.

 

yup, only on cold mornings, but my average has changed from a 10.6 to a 10, but once it gets hot out my truck is real sluggish, think I am going to take my air intake off and put my box back on, cept leave my intake tube on, then im going to run a tube from my bumper vent( no lights on work model)to the box, i made a seal type fit, but i took it off because im worried about getting water in my intake, and thanks hemi man, i also took my truck to the dump and had it weighed itz round 4500 lbs, i wonder what those jeep libertys weigh

 

I spoke with a flomaster rep and he said that the best for us is the 50 flowmaster delta. He says that because of the number of revs our 6 has to do compare to the 8. Also, dual exhaust is louder than single he says. So someone go get the 50 and let us know.

 

All true duals (two mufflers) is going to do is make you slower....alot...

 

Yeah Im wiht hemi man on this, two is just to much for the Displacement, you could get two pipes out of one muffler though, and you wouldnt lose near the backpressure, AND YEAH someone get the 50 and tell us what u think, i like my hooker, but its a little annoying when I drive medium peddle, sounds cool right before 3000, and sounds like a friggen (something) after 4000,

 

I think im getting mine done tomorrow, but i havent decided if i want the 40 or 50 series yet, i think i might go with whatever they say, the muffler shop im going to is considered to be one of the best in Eastern Oklahoma.

 

WTF, i hate my connection, i just sent a reply to this, and if fing dissapeared,wtf, newayz, ill go again, I think that u should NOT get a 40, any muffler with two baffles or less will sound like an airplane after 3000 rpm,anybody with a v8 will look at you funny, now if you dont mind the noise, and plan on getting more mods, like nitrous,(i know a good kit perfect for are trucks) then you should get a straight through muffler(no baffles) like the aero turbine, then get two pipes outa one muffler(thats what i should have done) so that u have sound on both sides of the truck, now im not saying that people with v8s still wont look at u funny when they hear it, but least they will be in the rear view mirror, but i u plan on no mods, then get the 50

 

The only time you get true duals is when your engine has a really high compression ratio or you have forced induction.

Correct me if I'm wrong.

With a performance muffler designed with v-8's in mind, I don't think you're going to get a very good sound at all after 3000 rpms.
Sort of "ricy" if you will (no offense to anyone).

 

no your right, thats why i recommend duals from one muffler for v6s or cat back.(duals applies to two rear end pipes, true duals on the other hand applies to 2 pipes with or without mufflers, with or without cats that only connect bye a x pipe or h pipe and run one pipe to each side of the exhaust manifold or headers)
