Bos Carbon Exhausts For Carby 900ss

Noooo… well, not for the same reason.

 

I was being sarcastic bud, I’m not so diminished by age that forgot something I learnt at 16.

My old 851 with a lot more horses barely faster than an air cooled 900 of the same vintage, unlikely.

 

No thanks. I'm going to hold out for something high level.

 

Something from the top shelf always work a treat.

 

Hmm... I have a set of outrageously loud carbon Microns on my 900ss that could probably do with repacking, but I'm tempted, and I've just booked a track day at Cadwell with a 105 dB noise limit (incredibly last year I measured 105.9 dB and they let me through with a wink).
Never heard of Bos though - Dutch company?

 

Bugger, I would have had these in a heartbeat but sadly had to sell my SS just before Christmas to make space in the garage, we have six in there now and it was just a little too crowded to get on with the restoration projects! Bos were a popular one back in the day but like Sev said they were overshadowed by the Termignoni dominance, I used to like D&D ones too but can't remember the last time I saw a set for sale!

 

Repack them. We have run Termi high, Arrow high, DP carbon low, DP alloy low and currently a single underseat Scorpion can on the track 900ss ie at Cadwell and it has never registered more than literally half as loud as yours! (Sorry for thread drift - lovely exhausts… buy them somebody !)

 

Yep, looking into repacking them now. Was flummoxed by the rivets which are 16mm diameter, but think I've sussed it now. It's a "wide flange, dome head rivet". I think.

 

Thanks. Gonna drill one out and see what I need to order in terms of diameter and length. Rivet head is about 16mm dia.

Any tips on packing material, or are they all much of a muchness? Been looking on eBay but its difficult to tell what you're actually getting.

 

After trying all sorts I now use this from ebay in this size, which is perfect for the 2x 400mm cans on an SS.

Ooh!! Thanks!

 

Thanks Jon - one roll is enough for two cans?

 

Yes, cut it into 2 400 x 500 halves.
