OOOOMG ... the car is louder than stock! I pitty the people who has to drive behind me... haha.

They are almost the same mufflers that come in the catback system from magnaflow but without the tips and a bigger inside (2½) so it has a very similar sound to that setup but mine is louder. Maybe a little too loud for my likeing but ohh well... I will leave it like that for a little while and maybe add something to quiet it a little bit later on this summer

Is there drone? - Only when the car is running
Powergains? - I don't know. It sounds mean around redline. My car should be on the dyno at eurocharged on May 1st. But I dont have before results to compare
