Best way to make the exhaust popping sound?
I'm still on my stock mufflers and will probably get the Turner muffler delete soon, but I was wondering if I could still retain the exhaust popping sound I sometimes hear while shifting at high rpms. This popping sounds like a shotgun going off and I love it, but I can't seem to replicate it all the time. It happens the most from 1st to 2nd gear and sometimes from 2nd to 3rd. I would push the rev to about 4-5k and then push it one more time and shift right away and it makes a very loud burst from the mufflers. Anyone have a clue what I'm talking about?

I have a Tubi Mid-Pipe and Section 3. My car does exactly as you describe but it sounds like a large caliber, high-powered rifle. It can be heard for nearly half a mile. The exhaust was the best investment that I have ever made. Good luck and please keep us posted! |

I just bought the Turner Muffler. It was on sale for 999. A steal.

I am eager to see what you think after this is installed. I am torn on either getting the Turner muffler delete or the BMW Competition muffler set which they also sell. Nothing has been said about how the BMW Competition mufflers sound compared to stock.

well if you're torn between those two, but you got some extra $ to burn get the BMW competition. it's the akrapovic rebranded as BMW for a little cheaper. I'd save my money and get the Dinan Stage I with the Turner and more.

Ways to create the exhaust pop
Speedracerlo,
I have a 2014 M6 with no mods. I love that sound and can give you some tips on how to replicate it consistently. First it is important to understand where the pop is coming from. It's un burnt fuel reacting with fresh oxygen and partially igniting from heat of the exhaust system. As the fuel air mixture ignites it heats up, expands and causes the BRAP we love so much. The un burnt fuel gets into the exhaust because the engine management system continues to inject fuel through the system to cool the turbine after it heats up from hard acceleration. Here's a few tips on how to get the system to BRAP:
Hope this helps. If your engine is already at operating temp, you can get the exhaust to brap while in neutral. Use sport plus. Do one short rev to pre spool the turbine. Just before getting back to idle, give a full throttle rev and abruptly remove throttle at 5,500 RPM ish (perhaps higher.) Use a higher RPM than you use for short shifting. You need the turbine to spool up and generate heat. When you pull back on the throttle, the engine will send fuel through the exhaust to cool the turbines. If the engine isn't hot this is a waste of time and if it is cold it won't even rev. NOTE: don't make the same mistake I made. Always check to make sure you are in neutral first. I pulled into a parking spot, engaged the safety brake and to satisfy a friends request attempted the rev but forgot I was still in first. Oops. |

That is a VERY important NOTE, It's easy if you are in a rush to move the gear selector the wrong way thinking you are in neutral when you are still in Drive. It will lead to a very embarrassing moment.
