Hi guys,
Sorry to bring up this old thread, this is my first post here!
I recently purchased a new 2023 Vespa GTS 300 Super Sport, the Euro 5 model that has the long exhaust mainflod with cat installed - similar or exactly like in the 'kandrani' pics above.
I want to install a Toro aftermarket exhaust (UK made) that works with the older/shorter exhaust mainflod (without cat).
Do you know if this mod will throw a check engine light or any other bad readings to the ecu etc considering that i'll be running without the cat installed?
Does the 2023 O2 sensor works with the older/shorter exhaust mainflod?
Thank you,
Alex
The guy in this thread did the opposite; he fitted a Euro 5 exhaust onto a Euro 4 HPE (think he did transfered the o2 sensor). He seemed happy after buying a Euro 5 manifold - claims the bike is running fine. So I'd be optimistic of doing what you want. But please note - might be less happy if you don't have any catalytic installed (ask toro if they sell a matching cat that I'd expect would install in the slip joint like most others).
PS I don't see on Toro's site that thare UK
made. Also looked at the pics on motorcyclepartswarehouse.co.uk and the silencer appears to only have one anchor point unlike all the other aftermarket gts exhausts that I've seen which have two (oem has 3) so would be less stable and put more load on the header bolts ...
