Exhaust Pop and Gargle?

Pharaoh2716 · 11-04-2010, 01:09 AM

I recently was driving my 2011 335i coupe in steptronic mode. I noticed that in first gear, if I barely feathered the pedal and revved the car to about 2000 rpm then let off the exhaust seemed to produce a gargling noise. I stopped and revved the car and heard pops when the rpms went back down. I was wondering if this is normal. I have uploaded a video to help better describe, what I am talking about.

You need to put an aftermarket exhaust system on to get even more pops and gargles!

Turbo charged car..

dre_2ooo · 11-04-2010, 08:36 AM

That's my favorite part of my performance exhaust!

The burble & gurgle sounds FANTASTIC with my AE exhaust and with an MT you have lots of control over it. I don't think I've come across anyone who doesn't enjoy that sound...

Umm.... Happens on NA cars too, on the overrun. My E36 M3 did it a whole bunch with the help of a much less restrictive exhaust.

Someone correct me if im wrong, but I believe its extra fuel that was not ignited being dumped into the exhaust and igniting; causing the popping sound. Which sounds bad ass imo.

Watwood · 11-04-2010, 09:19 AM

You need to listen to a 04-08ish Yamaha R1 with exhaust coming down the rpm range in gear around 5k rpm. I love the pops it makes.

I335 · 11-04-2010, 10:45 AM

The best example of this is a Harley Davidson with 1 & 3/4" straight pipes...

adrianBMW99 · 11-04-2010, 12:05 PM

One of my favorite things about this car!

BwoodBMW · 11-04-2010, 12:16 PM

We pay good money for that pop and gargle! I'm in the Love it camp.

Its the air getting trapped in the exhaust pipe.
