    I have a 2003 chevy silverado ext 4x4 5.3 Liter V8... I want to put dual exhaust on it that shoots straight our the rear... Ive been on youtube daily.. Im looking for a system that is DEEP GRUMBLY With not a ton of popping ... Im going to be lifting my truck soon so i want an aggressive sound ... What is the difference between the pipe sizes what difference in sound does it make? I am currently looking at the flowmaster supper 44 and 40 but am open to suggestions... I dont want a system that sounds like my truck is falling apart either i want it to sound like i have a nice set of duals... and i want to be heard when i pass people. Thanks Rylan

    Your stock 2.75' piping is more than enough so there is really no need for duals.

    This muffler ^ has a very similar tone to flowmasters yet it actually flows, and either dump it under the bed or get an exhaust shop to run them out the back. I had one on my truck and it had a great tone with out being annoyingly loud.

    With the 5.3, I've always thought that the ideal exhaust would be dual 2.5" after the cats into two round case, 14" long 2.5" inside diameter Magnaflows, or Magnapacks if you will.... I believe this would be deep and medium loudness, but surely not overly loud. I'm kinda curious as to what this sounds like, since youtube doesnt link me to videos I'm actually looking for much...

    Re: 2003 Chevy Silverado 5.3 Exhaust

    For now I would get the stock muffler cut out and leave as much stock piping as possible, it's stainless so it'll last the life of the truck. I wash the underside of my trucks regularly especially in winter and it keeps rust off everything. Anywho, I would start off with a cheapo glasspack and clamp it into the stock pipes. If you like it, have a shop slip it on and tack it in. With cats in place a glasspack usually has a fairly deep tone. If you really want duals, i'd go with that Aerochamber, a 14" case Magnaflow, Pypes Violator, Aero Turbine or a Spintech Pro Street. I understand wanting duals, I love the look of angle cut tips shooting out the back, look at mine:



    Unfortunitely those were on aluminized steel tailpipes so they rusted off and I don't have money for tails so I did this instead:



    But that's too loud so it's going out the back again when I get money for it.

    Anywho, hope that helps.

    Personally I have the 4.8l vortec in my 2003 silvy and I run a si/do single chamber cherry bomb with 3.5" tips. I love the way it sounds. Seems more agressive sounding and a little louder than the flows that I took off. I'm sticking with Cherry Bomb from now on!!
