Stock or quiet Muffler with Headers?

So here is an update. I ended up buying a $50 muffler from my local muffler shop. The brand is Flow II 22" muffler. It is "straight through". At first I thought it was way too quiet. Almost sounded stock even with my headers but after driving for 2 weeks it has really started to sound a lot better. I love the sound. Ended up being almost exactly what I wanted. Only cost me $130 installed and I can not tell any difference with power. Sometimes I think it even runs a little stronger. Maybe a little back pressure helped? I've heard this argument many times before wether back pressure helps or hurts on V8 engines. What do you guys think? Thanks

Do you have a sound clip of this new setup? I am in the exact same situation you were and need to find a way to tame this exhaust note a little. Thanks!

I had very good success with the maglanflow 22" when I had 1 7/8" American racing headers on my Silverado.

 

Before I had the Volant cat back (same as corsa but cheaper) and like 07softail said....I had to quiet it down for my own sanity.

 

I took some videos before I got rid of the truck with the whole setup on it but I loved the way the magnaflow toned it down.

 

this is a before and after headers so you can hear what I was working with....note I had catless headers

 

 

this is just removing the Volant muffler and welding in the 22" magnaflow, it was an offset in and center out 3"

I've got stock catback on my truck with headers and no cats. Not that loud, sounds good at wot and startup but it's pretty quiet in normal driving conditions

Flo Pro Big Oval (one in two out) on mine and dumped before the rear end. Really low deep rumble at idle.....no drone in cab and VERY mild sound outside.....basically a stock replacement for 6.0, but just a very little bit more noise. LOVE IT!!! :)

Thanks for all of the replies! So i guess the question is should i try a resonator, stock 2014+ 5.3 muffler, or 07-13 6.2 muffler?

 By any chance were you able to quite down tour truck man I’m currently having the same issue ?

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.
