LorinserLV2

Hi guys, the past week i had reeinstalled my OEM muffler and it seemed that it was from that time that my car between 3K and 5K rpm is less performant.

After i hit 5000rpm the car wakes up and normal HP is delivered....


It seems like something is slowing the car down between these rpm´s...Happened this to you already?

I´ll be changing my exhaust to brabus maybe next week so i hope the problem is from the muffler...

Any thoughts?

Thanks
