October 26, 2011As soon as I get the money I am going to be running new exhaust for my 01 2500HD 6.0L. I have a question reguarding the muffler/s. What would be the difference between running 2 si/so mufflers and 1 di/do muffler? Besides the fact that there will be one or two muffler/s. Is one set up better than the other? Also from what Ive heard the shorter the muffler the louder it is, is the correct? Any sugestions what size would be good for me? I am looking for something loud and deep but but none of that crackle and pop s**t.

November 4, 2011well, i don`t know for sure, but when running duals its always a good idea to equalize the pressure. hence the X-pipe. however, in my mind i would imagine a dual in dual out muffler would allow the back pressure to equalize too as long as the muffler allows the gasses to intermix. so if you have to run the driver side exhaust to the passenger side to run it back, adding more curves into one side than the other, building more back pressure unless they can equalize, meaning a dual in dual out could be preferable in that exhaust design. however, if you can run them both back straight down the frame or in a way that makes it so they are built the same way, i would imagine 2 single ins single outs would work fine in that application. Keep in mind, i am pulling at straws, i am by no means an exhaust guy whatsoever. just going through what makes sense inside my head. Being that your truck has the gas tank inside the frame rails, you`d need to either run the exhaust to the passenger side, or outside the frame rails. passenger side making more sense to me, but if you dump before the rear tires, you could run true duals back to the gas tank and put some turn outs there. if you want rear exits, ie anything behind the rear tires, i`d guess you would need to run them both to the passenger side, DI/DO muffler, and than run them to their exits. I could be wrong, but your best bet for a good reason would be go talk to a local muffler shop and they should be able to explain it to you easily.

November 9, 2011alright thank you very much!
November 9, 2011each person has different taste, different set ups,different motors, but from what i like is a clean hollow sound with a nice muscle car like tone. no popping/crackle. the corsa stuff sounds great if you got bucks! i like my magnaflow.not to loud until you get on it. if i could set mine up right now, i would go with lpp long tubes or thorley tri y`s in to a y pipe /W cut in and welded cats to a single 3" pipe to a si/so 18" or 22" magnaflow or a corsa and dumped. that way you get the performance of the piping w/ th e long tubes and a nice sound.imo if money grew on trees!!!!!

November 13, 2011I had a 2001 Silverado with the 6.0 as well. I ran 2 3" single in single our flowmaster original 40 series mufflers. I followed that with 3" piping to each corner and a 4"x24" tip on each pipe. The truck was very loud and the in cab drone was very high. I loved the sound though. I didnt get any popping under deceleration it had a great rumble at idle and low rpm and it flat our screamed above 2200rpm. I did lose some mid range and top end torque but not much. Towing on the interstate I could still accelerate without downshifting. I recommend doing your homework. Find a muffler with a sound that you like. Also I found that changing the length and girth of the exhaust tips helped alter the sound at idle and lower cruising rpm. The longer and wider the tip, the lower the tone.
April 22, 2012ok so i just cut off my muffler and sounds good. anyway i want to make a quick change set up for long trips and suck to shave gas with stock muffler vs glass pack so what clamps can i use that wont leak Walker Lap Joint Band Clamp i was told they dont. i kinda dont want to weld seeing how i can change muffler faster i have 3in pipes
