Ahhh yeaaaah Dung, your muffler broke in even better especially with the resonator delete! I was thinking of doing that too. I suck at semi-manual, school me on when to change gears cuz I can not get it right.
For the headlights I figured I'll do a year of Umnitza then go with OSS, I just want to enjoy both brand of products. On your OSS's do you see if you have like a missing diode/LED? I saw in one picture with an OSS it slightly did when looked at closely and individually, just wondering on yours if it was different/same.
