Title: single silencer exhaust Post by: dhla40 on 14 January, 2012, 04:52:35 PM I believe some 1600HF had an exhaust system with only one silencer, has anyone used one on the street and found the noise acceptable?

Title: Re: single silencer exhaust Post by: lancialulu on 14 January, 2012, 05:30:02 PM Aprilias for what it is worth only have a single silencer at the back and the sound is more than acceptable in all senses of the meaning! My Aprilia is 1500cc with fulvia pistons and engine is classic narrow angle v4 as Fulvias.
However I did drive Jai Sharma's racing HF (now owned by Ken Rorrison) that only had a small back box and that was a bit loud....

Mind you the marshals love hearing the car approaching at night!
