2014+ Exhaust Systems & Mufflers

jrob56 · May 31, 2016

Anyone familiar with the Gibson Metal Mulisha exhaust for 6.2L? If so what's the deal with the 4" piping? Sounds good as far as I can hear on YouTube just not a big fan of the exhaust tip but cant beat the price. I've used Corsa sport on 2 prior vehicles and still looking for that sound level but don't really want to pay the 1k price tag.

Volant is basically the Corsa with lower grade stainless, without the name and no flex joint if I remember right. 700ish but I found it a little cheaper on autoanything on sale.

thanks for your feed back. What other exhaust would you suggest?

That is a pretty loaded question .

It all depends on what you're after in an exhaust. It also depends on what side effects you're willing to put up with. (Helicopter noise if you have v4 mode still active, Drone if you go with a loud setup, etc)

Try the Flowmaster 50. I have had this muffler before a tune with V4 and after. Good either way. Kinda falls into that sweet spot. A lot like that childrens story with the three bears and that little tramp that broke in and eat all their shit and ordered a bunch of pay per view.

I am looking for a really deep sound but not to loud

Corsa is deep, but can be loud.

Borla is deep, but can be muffled if you get a larger sized muffler.

MagnaFlow, pretty much the same as Borla.

Flowmaster, isn't as deep, more loud.

These are my opinions and experiences.

I have it on my 5.3 and love the sound, it's a 4 inch exhaust for my truck also. I really like the way it sounds. I also have a range device to disable AFM.

I'd prefer just a muffler upgrade and obviously worried about the V4 sound being an issue. Been there / done that with annoying highway rides and it sucks.

Is it just me or do these trucks have a much deeper tone than previous generations? I'm not talking in stock form.

I've recently been listening to vids where guys are doing a muffler and resonator delete, the warm idle sounds so sick!! It nearly reminds me of a straight piped Duramax. I wonder if these trucks idle a bit lower than previous generations as well, that may add to it. Even revs sounds pretty good with the muffler/resonator delete. I am usually not a fan of the sound when people "straight pipe" but on this gen truck I'm liking it. I'm tossing the idea of doing it to mine.... I dunno tho.

Has anyone had muffler installed where the resonator was? I originally did the muffler delete and left the resonator in. I wanted it louder so I got a muffler I liked and it was small enough to be installed where the resonator was cut out at so I had the shop do that instead of cutting out the straight pipe we had already put in there. I'm assuming it wouldn't make any difference if the muffler is a little bit farther back right? I was thinking it would be louder, so that's why I am wondering.

Personally I never liked that the resonator looked like a huge growth in the fender well. I would just put the muffler where it normally would and change out the tailpipe also so it doesn't look all hacked up.

It doesn't bother me being in view of the wheel well, I was just wondering if it would make any difference.

Fixed the Y Pipe rubbing today, just cut out the corner of the transmission crossmember bracket.

After a year and half and having listened to many different exhuast setups I have decided to go with a muffler delete. I currently have the MagnaFlow dual rear exit cat back, and though it sounds good, it is just not loud enough.

I have listened to various different muffler delete setups and aside from the loud cold start they sound great to me. I will go in Thursday to replace MagnaFlow muffler for a stainless y pipe. The factory cats muffle the sound so much. I can't wait!
