Exhaust Hose

I'm planning to replace the 3.5" exhaust hose on my 1997 SN. The existing look to be original but I found they appear to have a fiberglass tube lining. I have been unable to find any reference to this type of exhaust hose and it's not available from either nautiqueparts.com or skidim. Does anyone know if this tube is intended to be removable or should I go with a standard softwall hose?

I'm a little embarrassed but finally figured out this is not a stock feature but another jerry-rig by the former owner. Why am I not surprised. It turns out, at some point the exhaust tube end at the riser collapsed and instead of replacing or fixing properly, someone with connections to Midas Muffler cut about 2.5" of the damaged end off and fabricated a steel sleeve on the end and put the hose over the top.


Although WakeSlayer will surely make another "straight pipes!!" comment, I decided to try to fix it figuring if it didn't work I would go ahead and replace. I started off using a rasp to rough up the surface and made cuts in the end of the tube so the fiberglass cloth and resin would better adhere.




I had to figure out some way of making a form but I couldn't find anything in my garage that would work with the 3.5" ID. I decided to use a convenience store soda cup from the recycling bin and some duct tape. 44oz. So far so good.



I mixed the resin, coated the end of the tube and cup with the first coat and applied one layer of cloth. I repeated the process until I had about three layers of cloth and resin.

looks good

So am I. The thing I can't figure out is, it would have been easier to do it the right way in the first place.

Confirming no on any sealant

I thought of doing that myself but when I got the new exhaust tube it already had a thin layer of what feels like silicone lube.
