I installed the exhaust friday. Sounds beast thats for sure. As for pissed off neighbors, yeah i could easily piss off the whole neighborhood, but as long as Im not on the throttle to hard its pretty tamed. If i get on it its louder than loud. The cops havent noticed yet. Saturday i pulled up next to one at a stop light, and once again just go easy on her and all is good. He didnt even flinch at me. Its only been a few days though so i may be eating my words soon who knows.
