Customizing my Hawk

Pretty much finalized my exhaust mods so I've copied over all the info from another thread. 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). It doesn't fall flat on it's face past 6K RPMs like it used to so I'm now shifting at 8K RPM (when trying to get up to speed quickly) and can really feel it pull with EVERY shift. I could do 55MPH comfortably all day long, even sustaining 60MPH is no problem at all if not fighting a wind.

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

Here it is all polished up:

This is the insert I purchased, but, what I received does not protrude into the muffler so I won't be able to hose-clamp a screen on the inside as I wanted.

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
