Z650 exhaust



Rather more perforated than first feared and (as feared) the balance
section is nowt but rusty metal.

Neighbour (skilled welder( is patching it. We're planning to just remove
the balance pipe altogether and patch over the hole on each side
collector.

I'm assuming that the balance pipe just reduces noise by a minor decibel
or two and boosts horsepower by the same infinitesimal amount.

If all else fails I'll stick a four-into-one on it for Chimay. There's
one on Ebay but the robbing cnut wants £25 for postage (parcel post is
under a tenner).
I've got a spare set of Zephyr downpipes if you want 'em, but I rather
suspect they'd be a little oversized.
They'd probably fit, actually - the 650/750 series all seem to have the
same size manifolds - but see other replies.
Any use?
Main difference I can see, apart from the looks, is that it has two
balance pipes rather than one, though I can't see that'll matter.

Main point is if I fit a 4-2, I'd rather it was utterly original, or a
replica.

I can see the silencers on that one already beginning to "bubble" and
they aren't replaceable as separate items, so on balance, a 4-1 would
probably be better, but thanks anyway.
