RE: No Muffler

Hey guys...sounds like y'all got an exhaust issue goin on. Tell y'all wut, this guy wants his truck to sound better and louder. I have 99 5.9 sport. I bought my truck with dual flowmasters on it. It sounded great like that but it wasnt loud enough for me, so i cut my dual pipes off and left the flowmaster on it. It sounded the same but it was definatly louder. After a couple days while driving, my truck started to sound VERY good i didnt know why! So i peeked up underneath and i realized my flowmaster had fallen off (crappy weld or something). So i have been driving with no muffler nor pipes, A.K.A. flowing right out of the cat with a 13" pipe coming off it. It is loud with the deep rumble...but the only issue is from 1300 - 1800 rpms there is a VERY slight rattle sound. The rattle isnt loud enough to **** me off but it exists. So i recommend completely taking off the muffler and pipes but leaving about 10" - 13" of pipe coming from the cat and it will sound excellent and loud with the rumble of the v8.
I've known quite a few people that ran straightpipe after the cat and split to duals out the rear of their Rams. Sounds really good. However, you'll want to run the pipes out the back of the truck or you'll suck exhaust fumes in thru the windows. A rear slider will be really bad, a sunroof will even suck fumes if left like this. Side windows won't be that bad, but you'll still get some. It also sounds better when it's not resonating under the box of the truck. Won't sound as tinney. (in reply to FiveNineMag)

RE: No Muffler
My Ram has had the muffler removed for over a year now, I just have the convertor and a single pipe split into duals ran out the sides behind the rear wheels.
Truck sounds great, has plenty of power and I get roughly 18MPG on the highway. I have the 5.9 also. First thing to remember dont go much above 2 1/4 pipe all the way out the back, keeps the back pressure in check.
I would say go ahead and try it, if you dont like it, takes nothing to stick a muffler in there afterward.
