What exhaust upgrade did you go with? Cool one from MBRP...

[RealMcCoy]

Sorry to hear you have a drone. I also have the MBRP and have not noticed any drone but will try and pay more attention. Let us know what MBRP tells you about how to fix the issue. I sure hope you don't have to swap it out.
Did you get the Stainless Steel version?

Yes it is the Stainless Steel "PRO" model. I love the kit. It is just at those cruising RPMs I get an elevated drone in the cab. If I back off the throttle it goes away but generally...your on the gas because you need to be. Best way to eliminate is to give it more gas and have it downshift which just takes the RPMs out of the drone range. I won't take it out. It sounds great otherwise. I'm just worried that the effected RPM range is where it will likely sit when cruising long distances on the highway.
I just spoke to MBRP. The woman I spoke to is going to speak with tech team and see if they can add a resonator or swap the muffler.

 

[Harold0819]

Okay, heard back from MBRP. There is no resonator option or different muffler. They said for me to try flipping the muffler around.
Any of you guys pay attention to the way yours installed? If I recall right it said for the louver openings to face forward. Anyone do anything differently? Sound like this will be what I try. Fortunately it should be a quick swap as I think I can just remove the small connection pipe in front of the muffler to flip it.

I had a thought come to mind a question actually. How long have you had your muffler installed have you given it time to break in.

Have about 700 miles on the exhaust. I'd figure it has broken in. I'm going to give it a little more time then I'll flip it.

Well with 700 miles you should not have a drone if it’s broke in. Run it to the 1000 mile mark see what happens Maybe the pipe will provide a deeper tone too. You may just be too attentive to the tone at this point.
I don’t not have a drone on my gladiator with the MBRP and I have the stainless steel too

I agree about the too attentive part. It really isn't bad and may very well be normal. The funny thing is I had my wife in the truck and she said nothing so it may just be me...LOL. But in her favor I have to add she drives a Hemi Grand Cherokee with a Corsa exhaust on it.

I just pulled the trigger and ordered the Corsa touring w/ turndown tip. Unfortunately it's on backorder and per @Quadratec it should ship by the end of the month. It's going to be a long 3 weeks.

Decided to spend some money so the FlowFX system will be delivered on Monday. Can’t wait to install it.

 

[Harold0819]

Glad to report that I solved my drone. The factory clamp that is on the end of the y-pipe where the aftermarket exhaust attaches was a little loose. It wasn't obvious but after tightening it a bit it solved the issue. I guess it was just loose enough that under load it leaked and being right under the driver seat made it very noticeable.

 

[whiteglad]

I smeared Never Seez on the clamp and bolt threads to get a good tight seal with the pipes at the taper joint.

 

[Gregbj33]

Installed the Flowmaster FlowFX. Install was straightforward. Very happy with the sound. Startup just barely louder than stock, but when you accelerate you really hear it. Only went for a drive around the block but so far very happy. Tomorrow’s work commute I’ll get both highway and street driving and will report back.

I had to retighten this clamp after a day or two also... guess the heat loosens it a little..... glad you found your drone...

i just chopped the factory exhaust and put on a flow master series 40. then had a shop bend up some pipe and it dumps just after the rear axle. $125 total cost, its tucked up better than the stock exhaust and sounds good ( for a V6) ill work on getting photos soon

I had a muffler shop remove the center 2 mufflers and install a Magnaflow.
