Which Muffler is best???

Velocity has more importance to the driver who regularly operates in the higher RPM ranges for extended periods. Back-pressure and scavenging are more important to the rock crawler and traffic creeper who want low-end torque. Most of us want something that falls in between. Not too much velocity that lower end response is flat and not too much back-pressure that high-RPM running feels laggy. Personally, when I look at dyno charts I'm looking more at the torque curves and where they are rather than peak HP numbers. Those will tell you more about overall driveability than a peak HP rating that is above 5000 RPM.

I agree with the previous post 100%

i have borla..and to me it sounds perfect

I've got an 18 inch Maganflow muffler on my 1500 sport, but was wanting to get it louder, should I go with a straight pipe?

Do you have a modified Y-pipe yet? Are you planning on headers? I would do those things first, if you intend to. No muffler sounds very raw and raspy to me, but some people like it.

I loved the sound of my Flowmaster super 40 true dual system on one of my previous chevy's, also like the magnaflow I had on a couple fords. Still up in the air about which way to go with this one. Leaning towards the flowmaster

Every customer that ever had Flowmasters and actually "dynod" the truck took them back off.

So you're saying the stock junk will outflow a 2 chamber flowmaster? I could maybe see that with a 3 chamber, but have a hard time believing it with a 2 chamber. I could be wrong though.....

Dunno about these trucks and Flowmasters but I had couple techs with hot rods,440 automatic Challenger, Duster with built 360,automatic that both turn FASTER times with mufflers(Flowmasters) hooked up then straight through the open headers.

I just installed the Magnaflow Y-Pipe and AT3030XL. Kept the cats and resonators. For me, it's perfect. Sounds awesome and throaty when you start it up and sounds mean during low RPM city driving under 2K. Once you get over 2K on the interstate it mellows out and has zero drone. When MDS kicks in it's really nice and quiet. Punch it and it roars to life.

Like most I was very up in the air on which muffler to go with, so many to choose. Have 09 sport with hemi, wanted it to sound like it should. Went with magnaflow 14", was worried at first going that small I would be that guy that the neighbors hated. Was really concerned with having drone. Have had it on for 2 weeks and loving it, very mellow around town but sounds amazing at WOT. Took first highway trip this last weekend, anywhere between 65 and 80 speed wise, no drone what so ever. Had mother in truck with me and could have conversation no problem at all. Have read complaints about sounding bad in gas saver mode but haven't noticed anything like that with mine. Left resonaters on so not sure if thats where they are having that issue.

Have had my mufflex 14 for two years. Still love it.

So which muffler is best? Looking at a Magnaflow 14 inch, but wondering between the SI/DO or the DI/DO. Performance wise which is best?

I have a 4.7 magnum with single 3 inch magnaflow it sounds great is a loud deep roar then dies down to a nice soft rumble aroun 50 mph also gives it a nice little rumble wile idling however not to loud you are still able to talk to you buddy with out having to scream and a in all 70 bucks go the muffler and install and all the pipe ended in a total of 105 bucks not to bad when you hear it

I have the 14" magnaflow snd love it. Go get you one.
