A big 14 Inch not big enough?
« on: September 12, 2017, 03:57:18 pm »
I am getting a Delkevic Exhaust but not sure which one.  Does anyone know of any issues with using the 14" Oval?  It is shorter and the exhaust will come out under the bag.  Not sure if there is heat issues with that and should go to 18".  Search just had to many results to find my answer.
Thanks

I have three Delkevic cans and all of them are 18". I think anything shorter would be too loud for most tastes. If you take the baffle out out of the 18" can it still has a great tone. And if you leave the baffle in be sure to do my Delkevic baffle mod.  Also consider the carbon fiber version they look great.

The CFs do not retain heat so do not radiate to the bottom of the bag.

But the hot exhaust gas coming out, mid bag, does produce undesirable heat...

I too pondered the same question before I got the 18" cf.  I just erred on the side of caution because I did read somewhere on the interweb that the heat expelled from the outlet could slightly effect the back corner of the bag/pannier...wish I could find where I read that now.. I would think sitting at idle on a calm day would allow the most heat transfer.

Hi,

Big 18" CF...... :great: >:D >:D >:D

Several 1000 miles on the short one. No heat issues at all in any weather (hot) conditions.

Drilling a 5/8" to 3/4" hole in the front of the front cone section of the baffle. If they still make the baffle with the solid cone on the front it kills top end due to too much restriction.

I have the 9 inch Delkevic carbon can.  Zero heat issues with bags on. You'll be fine with the 14.  The one model that does have heat problems is the 8 inch shorty, the exhaust exit is angled directly at the bottom of the right side bag with that one.
