I have an Erion Racing full system on my 00' XX right now and it has a very nice note, but I think I'd like to switch to something not quite so loud.
(as would everyone that lives on my street I think!) My question is this.

Is there a discernable difference in db. levels between a full system and slip-ons?

There are some sound files here (Joe's bike is there too ! :wink: )

There was a file where someone shows a difference between 1 and 2 pipes. Can't find it now...... The single pipe was more screeming, lass deep, as I remember.
Cheers,

Thanks Birdie, right after I posted this I realized I could have found my answer with a search.
