N54 to N55 midpipe swap noise question
Quick question.....
I recently swapped out my midpipe with a N55 midpipe. Everything went smoothly.....I love how much more responsive the car is. Now on to my question..... When I rev high and shift hard, 1st to 2nd, or 2nd to 3rd I get a strange exhaust noise. Its almost like a muffled pop. Maybe the noise is unrelated, or was there before now I can just hear it more. I will play around a bit more today and see if I can get more details. Could be my diverts as well. I say this because when it happens I cant hear them as I usually can. Thanks for any help! If it helps, I'm running JB3 on map 5 The rest of the exhaust is stock

It's unburned gasoline burning in your exhaust. Also known as a backfire. Pretty much every turbo car does this. You just can't hear it with all the cats in place.
Nothing to worry about. |

Perhaps the OP should have a friend drive his car WOT and change gears... with him following behind at night... when you shift you will see some fire (works). At least a small flame. |

I've heard many people doing mid pipes saying it sounds like a "french horn" kind of sound. I've debated on doing them, if only I could find a used set... I also have catless dps tho

That was due to the initial version of the Berk Tech. Race Exhaust. That was the only exhaust (Straight pipe) that had the issue. Since then there hasn't been any issues.
