the original was steel so rotted very quickly, from my experience, this made half the vire 12s out there noisier, and in one case i fixed, the corroded part fell into the pipe hole and stopped the engine so it was shipped to me for a simple repair then.
I had these made in s/s, something valmet didnt realy find easy i guess, so they never fail. its good practice any exhaust i get, i pull out the old one and cement in a new one
to remove, easiest way is to use a slide hammer with a hooked end, make sure the hook is catching top or bottom of the old baffle not the side
the other way, is to drill and tap 2 small m6 holes in its rim, through is ok, then pull the baffle out by screwing in 2 bolts that are lifted clear 10mm from it, by a bench made of a drilled steel bar, and 2 10mm blocks straddling the baffle rim.
to install, use fire-cement, exhaust assembly cement or high temperature epoxy, pack it in the sides and between the alloy and the baffle, then put a flat plate over the front face to level, invert so gravity drops the baffle forward, and leave to set overnight.
personally i install with the open slot facing down at 5 o clock, not 6 o clock like original because it should resonate less unequally.
obviously if the baffle is proud in your old hole, trim to fit with a dremmel so it will end up flat with front face.
