Wrapped Up My Pipes - Ducati.ms

999s · Dec 24th, 2011, 2:34 pm

In an attempt to not hear all the babbling going on in my house at the moment I will be sharing my freshly wrapped Termis!!!!

As I have never done this before and didn't want to waste materials, I enlisted the help of my painter Levon.

This is what we used...

All the parts...

One down....

All wet and junk..

Drying em..(I'm not known for my patience)

After applying some paint...

Voila!!!!

And the smoke....

After a good ride yesterday I have had very much fun having people roll up their windows at stop lights because of the smoke billowing off my bike!!!!

Looks good.
I've been wanting to wrap mine. Does the fabric get hard or stiff after it cooks for a while?
Why the paint?

I've been thinking of doing the same thing. Nice work.

Tidy! Wrapped my carby pipes earlier this year:

They did smoke excessively for a while until they had dried out, lots of concerned looks at traffic lights etc...

TIP:
When you change your oil next, wrap the hot pipe underneath the drain plug with tin foil, this will stop the oil saturating the wrap & causing an EPIC amount of smoke (think film effect..) when you start her up again.

Cleaned the pipes up & painted them with two coats of hi-temp black (would stop them rusting again under the wrap, plus the wrap is applied wet to allow it to stretch a little for a tight wrap)

Cut out the collector box with a plasma cutter beforehand & rewelded with a star in the middle to allow better breathing...

MUCH less restrictive!

The star is a short length of (I think..) 50mm stainless tube quartered & held together with a jubilee clip whilst it is seam-welded.

Im just about to start modding my spare headers with the same cut-and-paste on an exchange basis for my friends headers - who is making me a pair of CNC alloy exhaust header rings into the bargain...

Legend has it the collector is over-restrictive so the bike will pass ride-by noise tests, even with "free-breathing" cans? The collector mod was a necessity on the early 851's to get them breathing freely...

The exhaust note deepened after the mod, spins quicker in the higher revs - I can't vouch for any HP gains without a dyno run, but the bike has never been a slow 'un.

I picked up an opened up header on ebay but I don't think it has the inside diverter. Be nice to see what works best. Nice work!

Tidy bit of fabrication on an 8-valve system:

Also another variation on the theme?

The aim is to divert the gases from the opposing headers around and away from the other one as smoothly as possible into either exhaust can- yes, the standard system does in theory allow half the area of the header pipe either side of the collector but it is very badly *pinched*, almost diamond-shaped?

Big twins need to BREATHE...

Why the paint?

When you apply the wrap ya wet it so you get a nice tight coverage. When you do, some of the color comes out, so you apply the paint to make it pretty. As for hard or stiff, he he, it seems so far to be pretty stiff but to the point of brittleness.
