On a side note, the muffler is too loud for me around the 2000-3500 rpm range, it drones badly in the cabin. At idle it sounds awesome and at higher Rpm's it sounds pretty good. I think I am going to buy a large magnaflow resonator (18" or 22") and see if I can cancel most of the sound out.
My mpg's have gone up about 2 on the highway and about 1 around town. Throttle response was also improved.

hehe i have the same issue... the drone at 2k sucks! its just the nature of the 3.7 engine

Re: 3.7 Mufflers, whose got'em?

It doesn't sound terrible but I can see how it could drone.

Re: 3.7 Mufflers, whose got'em?

I have the 3.7 with the dual SRT8 exhaust, no muffler, cats going to a single pipe then a "Y" back to the dual SRT pipes over the axle and the dual SRT resinators and tips. I noticed ALOT of water coming from the tips, like if im sitting in my car on lunch break there is a big puddle on the ground below the tips. Is that normal?

Re: 3.7 Mufflers, whose got'em?

Thanks for the compliments. Ya I really like the sound of it during idle and the drone has grown on me while driving (it only drones really when going up hills). I still might end up installing a 12" magnaflow resonator, just might wait a month or so.

sms07h, I paid $30 for the install.

Acid, trust me they are still on my list, even though I just bought some sport rails but I was offerred too good of a deal to pass up.

Is drone caused by the exhaust coming out the tips?

Re: 3.7 Mufflers, whose got'em?

Its only gets loud when the rpm's are around 2000-3000k and when the engine is under stress (hills, sudden acceleration) and yes it seems like the drone is coming mostly from the rear. Ive thought about sound proofing it, just dont want to bother.

Im contemplating pulling the gibson off and going back to stock, but I really dont want to loose the gas milage that Ive gained. I just cant pull the trigger to purchase a 12" resonator and have it installed only for it to still drone.
