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. http://www.amazon.com/gp/product/B001654JK0 Last edited by pcspecialist; 09-02-2016 at 01:25 PM. |

I bet there is a thin piece of stainless tube that would slip right over the existing tube, between the tube and the flange. It could then be welded in place, allowing you to attach screen.

Maybe I'm missing something here....but why not just cut a round hunk of screen the same size as your muffler and sandwich it between the nozzle and the muffler on the three mounting screws?
I should have probably read back further..... Apologies if I missed something.

for the same reason filters for garden hoses and washing machine hoses are not flat, but, instead are dome shaped..... flat would restrict air flow. Need more surface area.

Or a flange cut from steel.

it would be getto as fk but you could cut a tin can and roll it to the right size you jam between the pipe and flange as a pipe extension, then wire tie a screen cone onto that.
not sure how hot that exhaust tip gets but maybe could use some high temp solder to hold it in place.

pc doesn't want to be my friend on FB. Maybe the Michael thing confused him?
