Ok so I want 3" diameter and something quiet on idle but producing a nice note at higher RPM.

So I guess that means a mid-muffler and a cannon?

Need something that is available also. Don't want to wait months for it to come from Japan.

 

Blitz nur spec R.

 

Won't that wake the dead?

I want a quiet idle.

I like in a fairly conservative, quiet area and don't want to start pissing off the neighbours basically.

 

get a Hayward & Scott, perfect for you, I swapped my loud (Cobra) exhaust for a H&S and it's much better

Revolution 3 inch system, quiet, lets raw when booting it.

 

Personally would say a hayward and scott system,well madeand probably what your looking for:

Failing that the the scoobysport back box is quite subtle,and roars as the revs rise

kakimoto full mega n1 with bung, not noisy with bung, nice sound, but remove the bung and you can call the hell!!!!

 

im getting a full decat fitted to my classic tomorrow, hayward and scott downpipe mid pipe and graham goode back box meant to be not too loud will let you know how i get on.

 

my sti V has an hks hi power system an its quieter at idle an a cold start up than the 2.5 inch bore scoobyworld ninja 1 system on my uk classic different story above 3000rpm though!

Or theres the hks 'silent' hi power system as well. Think scooby parts stock both.
