LoL, my UPS delivery gave me a heads up and told me about how loud my bike is. So definatly if you live in an area where cops will press you, I really wouldnt advise you to take out your baffle to make that much noise. And trust me IT MAKES ALOT OF NOISE!! It sounds really aggressive exspecially when you have gears on it.I just took my baffler off today, and I must say the performance gain is phenomenal! I have a jackshaft kit and before I took off the baffler it didnt really utilize the gears good. But now IT HAULS A**. I can get up to 35mph in about 10 seconds, and the acceleration is LOVELY. The only thing is that it can get a bit loud. Really and truly I would recommend a Tuned pipe, or expansion chamber b/c you will be able to harness this effect, and still utilize back pressure at high RPM's. SICK BIKE PARTS RULE!!!
