MBRP Street Drone?

OrangeRush · Apr 25, 2016

So I just got done installing the MBRP Street cat-back system on my 2016 GT. I've got the CS package with stock gearing. It's a manual.

I've only put about 50 miles on the car since I installed the exhaust, but it seems I have some drone at ~70mph in 6th gear, which happens to be ~1900RPM.

I should mention that I came from a Subaru STi that had unequal length headers. On top of the UEL headers, mine also had an SPT cat-back exhaust system which is (supposedly) one of the most bass-y exhaust systems available for the car.

The STi made a LOT of noise -- most of it humming/rumbling -- on the highway. My 'Stang with the MBRP is definitely quieter, by a long shot, but the sound it's making is not entirely pleasant. It's almost like I can "feel" the sound inside my head.

I'm wondering how many people have any discernible drone, and if any change was noted over time (better/worse)? Also, is it possible that I have a dud or maybe I booged something up during installation?

Hmmm...

So I just happened upon another thread where someone was talking about "j pipes" being added to their system. I'm not familiar with this term, but I assume it's a form of resonance chamber?

I'd be very grateful if someone could provide me with a link that pertains to the 2015+ mustangs and "j pipes". I imagine it needs to be a specific length and size (I/D) to work, so knowing what to build for mine would be awesome.

Do a google search on the Solo Performance exhaust system for the 2015 Mustang.

You'll see the J-Pipes.

I had the bassani x-muffler catback which drone really badly and I ended up selling it and buying corsa with no drone. I've heard mbrp does drone.

I installed the mbrp street this weekend along with the k&n air intake system and I have minimal "drone" at very low rpms ONLY. I did a 300 mile journey back to NC going 70/80 and the cabin was super quiet. I DID notice that when I got home the sound had changed from the initial higher pitched loud sound to a much deeper ballsy guttural tone. I guess that's what people say about the MBRP breaking in and letting it's true sound come out. I put around 400 miles on it this weekend after installing the intake 1 day and the catback the next day. I averaged 29mpg coming home on cruise control.

I worried about the tips flying off but we torqued them down pretty good so they were fine lol. I would adjust the TIPs a bit because I heard the more flush the tips are with the rear valence (how deep the inner pipe is inside the tip) might affect the "drone."

Coming from an exhaust on my 3.5l HO Dodge Charger I do notice that any aftermarket exhaust will drone T some point some rpm but as I do more
Short slow trips than long hard trips I like hearing my exhaust otw to work and watching ppl go wtf... That things a beast lol.

I would check that all the connections are tight. Tons of people running the Street version and saying no drone.

Mine is an auto but I've never had an issue.

No drone.

strengthrehab · Apr 25, 2016

Not a bit of drone here.

Asonitez · Apr 25, 2016

I would add i'm also an automatic.

No drone here...tons of rasp though; MBRP Street. I find drone though is a factor, in my car, of being in too high a gear and low RPMs. I typically won't touch 6th gear unless I'm 70 or higher. In 6th @ 60 and ~1500 RPM sure it has a drony sound to it but I'm just not pulling enough RPM for the gear I'm in. Drony as contrasted to ya I can hear it and it's not booming in the cabin and tiring.

shouldn't have any drone

let me know on the mbrp, we'll get you setup with some great buys!

My MBRP Street doesn't drone at any RPM at any speed. 3.55 gears and a tune.

I came from a '15 STi with intake, downpipe, and catback so I know about the volume lol. This is way quieter with no drone at all.

It is however raspy at WOT. No denying that one.

no drone just crazy rasp.

I should be picking up my 16 GT this week. I may take you up on that exhaust. :thumbsup:

2016 GT PP MT. No drone, ripping good sound when you hit the loud pedal. Some people complain about the rasp, I like it. You will get attention when you want it and can be quiet when you want to sneak....sort of.
