I have a 2014 silverado with 5.3. What would be better, a cat back system from gibson, dual sport exhaust system ? or just swap out the stock muffler to a magnaflow muffler.

 

I cut the stock muffler out of mine, leaving just the resonator in place and it sounds really good. Nice and quiet at an idle but you hear it on the peddle.

 

How does it sound when it goes into 4 cyl mode?

 

Any sound clips ?

 

I posted some clips on here in this section a while back. Its in the thread when I bought my truck new.

in v4 mode you don't even notice a change until you tip into the throttle to accelerate, at that point it switches back to v8 mode almost instantly so you don't even know really.

 

Cool. Thanks for the info, Noah.

 

I would have a hard time hacking up the exhaust on such a new vehicle... just my 2 cents.

 

Aw hell, Vortec, it ain't really yours till you've cut it or drilled holes in it!

 

hah! I just mean I'd rather get a bolt on system and unbolt a nice unmolested stock cat back as well... this way I could still sell it as stock down the line.

 

that's the beauty of it having the resontaor there still, to the untrained idiot it still looks stock! Mine had ~400 miles on it when I did it
