exhaust too loud? solution: kill neighbors
serious note: I am running straight pipes and they are ungodly loud. I have not gotten complaints. only issue I had was based on the volume and look some dbag on my drive to work accused me of speeding and whatnot.
but I agree with the others of being gentle in your neighborhood. it's all about respect. you show your neighbors some by not going balls deep in the throttle then they are less likely to bitch.
I do feel bad when I start mine at 7am cold starts are on a different level. even more so since I start it up inside the garage.
