Hi Am looking for a supplier of the middle section made by magnetti morelli part no. SS500C which is direct replacement for removing centre box. Cannot find any uk supplier who can help it is going on with a prowler back box to my 100HP.
Have seen a Remus version but its more money from what I heard the 85 squid the magnetti one is.

I'd email or phone Shop4Parts - a Fiat/Alpha specialist who stocks many genuine and Magneti Marelli parts.. Sometimes they can sort you out as they're also the only UK suppliers of many Italian car parts brands

Only place I've seen it is eBay, but it's a two week delivery from the continent, £80 delivered. If you centre section is in good nick, might be worthwhile going to an exhaust specialist and having the box deleted. It cost about £25 in parts, I did this to see what a Marelli would sound like.

Hi, I might have one for sale soon if you don’t get any joy from fleabay.

I had one fitted but didn’t like the sound as the aftermarket rear silencer dominated the noise. You could hear the good noise in the background but it’s suppressed by the back box.

I wanted the MM SS500B back box and it was cheaper to buy them both again rather than seperately. The centre section has arrived but the rear silencer has gone walkabout.

When it’s all sorted ~ I’ll post it in the for sale section.

Cheers!
