Hey Y'all. I got a 99 dodge ram 1500 with a 360 magnum and I've been looking to get a new muffler for sound (and maybe a SMALL mpg boost). I've looked at some cheaper kits (I'm pretty broke), but I wondered if I could take a cheaper route. If I just bought a muffler, could I cut off the stock muffler, install the aftermarket one, and use all the stock piping thats there? I would have to clamp it on, and I know I can dump the exhaust right after the muffler, but I would prefer to use the stock piping before ( from the cat) and after the muffler (to the tip out the back of the truck). I realize an aftermarket muffler would be a lot shorter than the stock muffler, so would I have to just get a piece of exhaust tubing to patch the distance? Sorry, might seem like common sense stuff, but I'm young, and stupid, and like to ask questions. Thanks in advance. I dont know what I'd do without you good folk here on dodge forum.

 

It's all together with clamps, my 99 is anyways. Shouldn't have to cut.

 

Want a "slight" increase in MPG's and a little more power? Read this,

pretty sure my plenum is good. The truck has been running pretty good (havent had it that long) and looking past the throttle body, I dont see big pools of oil, just very small amounts of residue. Right now I dont have an pinging, and average mpg I've been getting about 13.4 mpg, which I think is pretty good for a 360

 

So would i be able to just remove the stock muffler, install the new muffler and some piping to take up the shorter length and still get a good tone?

 

If it is all clamped together..... depends on who assembled it. Sometimes, they run those clamps pretty tight, and crimp the pipes. Only way to get those apart without cutting, is a torch. heat 'em up cherry red, and then twist and pull. Without heat, you won't get 'em without cutting them off. Of course, then you could just get a slightly longer pipe to take up the slack of what you cut out.......

 

If I have to cut it, it really isn't a big deal to me. I'm just trying to figure out all I need parts wise to replace my stock muffler with a glasspack, still using the stock piping. What size is the inlet and outlet of the stock piping, its 2.5'' tubing right? And would I need couplers to connect the muffler to the stock piping?

 

First post in this thread will give ya the dimensions and such.

 

Thanks Hey You, I did my exhaust tonight. Instead of wasting time with the clamps, I just used my sawzall and cut the stock muffler off, installed a thrush glasspack, and ran the piping just before the rear tire. Now I just need to get a tip to finish it off, it sounds so good. Best part was with the muffler, clamps, and extra piping it was only $48 out the door at advance auto. I decided not to use the stock tailpipe and just dumped it early and I think it sounds better that way,

 

Got a video of what it sounds like?
