Removing sleeve RRP mani to run pfp

[Robbie8984]

I have the RRP exhaust system on my ski.

Realising how I want more mid now I'm doing multiple flips etc.

Has anyone removed the sleeve? Didn't realise it was in there till I measured up to see the difference and there is a ring round it at 73mm that's PFP size

i really dont see how removing the sleeve will help if the carbon pipe is the same size as the ring i do believe! i have herd of some porting done to the mani and carbon pipe though

Was thinking maybe since the sleeve
is fairly thick walled, drill and tap (3)
6x1.0 holes into the face of the sleeve and use a steering wheel puller with (3) 6x1.0 bolts and some sort of metal placed into
Manifold for the forcing screw to push against. Heat the manifold flange around the sleeeve and try to extract the sleeve

Didn't make that to clear... I want to change the chamber to a pfp, so need to remove the ring so that it will fit.

I just checked the ring and it has a wall thickness of 6mm

I'll give that a try with 5mm holes and a bit of heat.

Not easier to cut the spigot off flush with the flange on the PFP pipe, can always weld back?

 

[restosud]

isn't the sleeve welded on?

Doesn't look like it on the newer mani. U can just see a very faint like where the join is

How did you get on Robbie, feel much difference in performance?
