Well everyone has complained about how loud the DG exhaust is that I put on my XX. So being tired of everyone whining I decided to see how much difference there is. A friend of mine has a Yoshi on his cbr that we had realized has the same diameter input end as the input on my DG. Since that meant the intermediate pipe on my DG would match and the only difference would be the length for the cbr was a little long we decided to try it and see what it sounded like. It not only is just as loud as the DG it sounds exactly like it. So I'm sticking with my DG for now.
I did that experiment on my raptor when i had a stock cbr600 pipe.
the cbr was so quiet with stock, put it on the raptor and it was loud !
Put the raptor aftermarket pipe on the cbr just for a laugh and it was still quiet..
Just shows how much more quiet a multi cylinder is compared to a single thumper !
