CB650R CB650R Termignoni Relevance exhaust owners?

dz · Aug 23, 2023

Hi, does anybody have the Termignoni relevance here by any chance? I'm trying to find performance specs for it but can't find anything, emailed Termignoni directly for info but no reply. This is the specific model I'm looking at;

H161094SO01 Exhaust System - Racing | Termignoni

Discover the H161094SO01 exhaust system for Honda CB 650, Racing

www.termignoni.it

I prefer the aesthetics/sound over the Akra but it would be nice to know if I'd get a similar performance boost to the Akra (after a tune) any help would be greatly appreciated. Cheers

i installed this exact one about 2 weeks ago. it is a full race exhaust, so no cat, "DB killer" is a joke. it was too loud for my taste out of the box, but with a baffle and packing, it sounds just right to me. it definitely has a deeper and louder note on idle, up through 3rd gear. once up in the gears, the sound is not noticeable, just wind noise in the helmet at that point. i am happy overall. the weight savings are great, and this thing is beautiful. bike does seem to have a bit more pep, not sure if it is just the weight savings. just dont forget the new gaskets and some goop to keep them in place! no tune, bike runs fine, no error codes thrown. i also preferred the look of this one over any other system. PM me with any other questions...

hi sir hope youre doing well, i recently bought an aftermarket muffler and was bummed out that ill need a tune if i Cat delete cause its over my budget and at the same time worried that it will harm the bike (cat delete) so I figured I install a catalytic converter from a hayabusa(half of it cause they got double jointed cat)
And then the muffler again with no tune. would you care to share your experience with your cb

i have the race version termi (no cat). i did add a baffle and some fiberglass packing to decrease the sound. no tune needed, bike seems to be running great. seems like a bit more power, def less weight! i think the cats are only needed for emissions etc, i dont think the bike needs one to run. others will correct me if wrong

Do i need the fiber glass in the baffle , how loud would it be without the stuffing (no cat)?

you dont need the baffle or the fiberglass. sound is subjective, what is too loud for me may be just right for you. without the baffle and fiberglass, it was too loud for me, and i was not enjoying riding. if you PM me, i can send you an email with stock vs termi starts

I'm thinking about installing the So05 or So02 version, I'm in doubt between these two. What did you feel on the bike after installing the So01 exhaust?

not sure what you mean by "what did you feel on the bike", but the bike did feel lighter once the termi was installed, esp on turn-ins. it is def lighter than the stock system. once i got the sound sorted, it is perfect for me. it is louder than stock in 1-3 gear, but then quiets down to near stock levels in the higher gears, so it is not annoying to me or others on longer rides. hope this helps. just dont forget the gaskets!
