Exhaust system on a 2016 gasser

Anything that's not stainless will be rusty looking in 2-3 years, unless you lived in TX, Phoenix, AZ or Southern CA.

 

Usually non-stainless systems will rot from the inside out too, due to the acids in condensation from combustion byproducts. Short trips in cool weather really do them in quick. The more you drive, the longer they will last.

I wasnt looking at Magnaflow just because I have it on my 06' 2500 ext cab and after 5 years it got to me. I want little less drone. My shop did already recommend that.

 

As far as 3.5", thats just what is on the truck now and was trying to stick with same diameter thats all. That Mag flow system seems like good fit, but I am concerned about drone as mention before. AND, mine looked terrible after few years covered in surface rust.

 

I went with the long body Magnaflow one inlet, two outlet muffler, no drone. I also did not use Magnaflow's system, just their muffler and two tips, rest was done in custom bent and welded stainless. I think the long body muffler makes the difference in the drone.

But you do not have the 6.0 ? Think would be considerably different, no? Is your 3.5" like the 2016?

 

What I would love is a sound clip of the same system on a 6.0 . I think its 5"x8"x18", the one for my truck.

What is part # of the muffler? I want to find sound clip with 6.0

How long is "long body"?

I'll add that while Flowmaster has a nice sound, their quality is unimpressive to me. The last time I ran one of their kits (granted this was like 12 years ago now), the clamps rotted off after one winter, causing the tailpipe to fall off. The muffler stayed but looked like absolute crap. It was still there 4 years later but I doubt it had much life left. I had the dB system on my last Silverado (basically the Corsa Sport muffler with lower-grade stainless pipes and tip) and it held up great. Under full throttle it has a glass pack-like sound and under cruise it's a pleasant rumble.

 

All that said, exhaust on a modern, non-turbo engine is strictly eye/ear candy. The "restrictive" factory exhaust is a myth and at most you'll see single digit gains typically. Regardless, every vehicle I've ever owned has gotten an exhaust and I see no reason to change that.

Ok, I am still deciding and appreciate all the input. Since most agree it is not much gains for doing dual, what if I did it all from the engine.

 

New shorty headers, with the magnaflow custom system from my shop. I can do the high flow cats but I think it would make it louder no? also, I can install resonators if there is too much drone still.

 

what do ya'll think...
