2014+ Exhaust Systems & Mufflers

[14SLTZ71]

So to clarify the GM Borla system should/will not have any drone in V4 mode? I want a subtle growl, no drone, and do not want to diable V4.

I haven't installed one but it comes with the same valve that your factory exhaust has. It should be 100% drone free. I haven't heard anyone complain about the GM Borla kit (GMPP exhaust).

 

Reach out to Strykers_Inc, Daniel T, or Trwtow they have had theirs long enough to give you a good assessment.

Here is a link to their posts.

Since you are in Texas you could also go see Kirk Robinson at Kinney's Muffler Shop.

Here is 3 examples of his work.

Where did you order?

Ah that first truck with the true dual flowmaster sounds so good.

[Daniel T]

GM Borla dual rear exit....sound is getting a bit better as it runs in over time.

Nice growl under acceleration, quiet at cruise, no V4 drone!

Worth the extra cash

For anybody thats installed a borla on a 6.2 do you have the pArt number for the muffler only? Or does anybody know of a borla muffler thats 3.5"

Inlet with dual outlet. I can find 3.5 imlet and outlet but the exhaust shops around here cant bend more than 3" pipe

that first video with the flow master sounds perfect. wow

Probably an odd question for a GM forum but.......

 

With all the concern and talk about the V4 drone/helicopter sound or whatever you want to call it, I was just wondering, does Dodge/Ram have the same issues. I'm certainly not up on Ram trucks, but I thought I read somewhere that they also use a type of "cylinder deactivation" in their trucks?

 

Just wondering.

Looks like Dodge Hemi's have the exact same issues with their MDS (aka AFM).
