Hawk Stock Muffler with Pro Circuit Quiet Insert
I had already decatitated the exhaust and drilled holes in the muffler, but, didn't notice much of a power gain so I decided to increase the opening on the end of the muffler by replacing the stock insert with a Pro Circuit one (which is a bolt in replacement). My top speed only went from 62MPH to 64MPH, but, mid-range power has significantly improved..... I get to 62MPH much quicker. The engine isn't fully broken in yet so hopefully I'll get even faster speeds in the future.
Drilled holes inside muffler with a long bit I have for running cables to reduce back pressure. The plate inside the muffler is further away than the zoom lens make it look like. Probably too many holes, wish I had used the larger insert instead of stock one when I was test driving between hole drilling (there are more than you see in the picture). With the insert installed This is the insert I purchased, but, what I received does not protrude into the muffler so I'm going to find something different as I want to be able to hose-clamp a screen on the inside. http://www.amazon.com/gp/product/B001654JK0 Code:
don't know why it keeps changing it to amazon.ca (where you can't even get it) here's the url you need: http://www.amazon.com/gp/product/B001654JK0 You can follow everything I've done to my Hawk here (will eventually add the insert mod once I've narrowed down the best insert): http://www.chinariders.net/showthread.php?t=16636 Last edited by pcspecialist; 07-18-2016 at 07:59 PM. |
