    Would you say it’s loud enough to piss other drivers off and get tickets or just a different tone than stock? To me it just sounds higher pitched as well as a bit louder. Also are their any engine mapping changes needed to keep it from running lean?

    Have you guys ever worked with or seen Feynlab's Self Heal Plus ceramic coating? I've installed it on over 100 high end vehicles in Orange County and San Diego. There's nothing else like it in the world...dead serious.

    If I owned a GT3 RS I wouldn't change a damn thing. The stock setup is perfect, you probably just made your car slower and worth less money.

    Germany (EU) mesurement is metric, not zoll. Your fork key 10 zoll has not the same size as the German tool, fork key size 10 metric. The metric stuff is placed in german Cars/ made in germany ( audi, bmw, opel, mercedes ). M= Metric = metrisch.

    Btw. That’s why I hate electric cars. I wouldn’t care if your car only went 80 mph. It’s still better because driving is a full sensory experience. You HAVE to have the right sound.
