Slight popping sound with new Akra Evo
Installed the Akra Evolution with CF tips a few days ago. Freaking awesome sound, love the roar
When changing up gears, I hear a slight popping sound from the exhaust - is this normal? |

Change you gear change speed to a lower setting. The faster the gear change, the louder the pop.

Normal, I sometimes can detect it with the stock exhaust system. With my EI X-pipe (HFC), it's more pronounced. That popping sound is, I believe, a small void in constant exhaust gases moving through the pipes from when the engine rev's down, then back up. I hear it more as after a downshift and rpm's drop. It's not back fire though. Back fire is unburned gases re-lighting and being expelled.

Almost every high performance car makes the popping sound, it is just not as noticeable with quieter exhausts. A 911 GT3, Ferarri 458, Lamborghini Gallardo, Audi R8 etc. (the list goes on and on) make popping/backfiring sounds. Shit, even the 2012 Mustang 5.0 rental that I have been driving for the last few weeks makes popping sounds on deceleration and upshifts. I don't think any of the above cars qualifies as a beater. I understand opinions are just that, but I don't think you will get many people to agree with your opinion. To the OP: Congrats on the Akra!!! I have had the Akra Evo on my car for over a year now and I can tell you you won't find a better exhaust on the market if nice sound, good performance gain, quality/fittment, looks, and a lack of drone/excessive cabin noise are important to you. I think there are some other systems out there that may have a nicer tone than the Akra however none is as good an overall compromise.

Do you even really own a M3 or do you just come here to troll?
