Best exhaust for 6.2

Je_suis_prest · March 17, 2016

Been tossing around the idea of having a muffler installed. I would leave factory piping simply cuz it's stainless. Had an Imco (identical to flow master) put on my last denali. Sounded great! Wondered what you guys have installed, if any. Thanks!!

Corsa or Borla cat back.

But so you know there will be "helicopter" noise when you go into V4 mode. Unless you have it tuned out, or install a Range device.

I'm a fan of the muffler delete myself.

Do Magnaflow 12909 in place of OE muffler and flapper valve. Any competent exhaust shop should be able to cut out and replace with no issue. Including labor for install mine ran about $155-$160 granted I had a discount coupon from Advance Auto when I ordered. Great sounding at startup and a deeper tone plus minimal drone in V4 mode.

I have that same magnaflow 12909 on my truck, I do love it it. Had no drone at 75-80 even with headers and no cats

What is the "flapper valve" and did u have the resonators removed too?

Leave muffler and delete resonator and valve. BTW if you do remove the muffler I want it.

Cut the resonator off and add a 5 inch tip. It'll sound great.

I have an MBRP and honestly get nothing but compliments on how my truck sounds....... that said..... I wish the factory tailpipe wasn't such a goof ball design with the flapper and resonator in it as the MBRP 409 tubing will rot off this truck long before the stock system would have even shown corrosion. If it weren't for all the hacking I would have had to do I would have just swapped mufflers...... but by the time you delete that retarded valve and the resonator you may as well buy a kit.

Flapper valve is directly behind OE muffler and is designed to cut down on drone when in V4 mode. I did not have the shop remove the resonator and exhaust sounds fine.

This is me... not being cocky but for the 2014-up gm trucks this sounds amazing. I've since have clamped open my valve. And sound is way better. But invisible helicopter follows me

Thought of an exhaust. Built it in my head. Did a Lil research. Bought a borla and xr1 muffler. Corsa look alike tips and mandrel bent tubing.. yes I still have my 3rd cat. And yes i have my valve.. check out my other videos to hear more. I made a video of me crawling under the truck to show what I have Edited March 18, 2016 by Silver ice 6.2

Am I voiding all warranties removing everything?
