can any one tell me if aftermarket headers make any difference other than being flashy bling ?

don’t think anyone has done it AFAIK. Probably need a map update for fuelling but to date i don’t think its been done to a 1250.A friend of mine did it to remove the cat. He hasn’t mentioned any performance difference. He’s not getting errors but is concerned about euro 5 updates down the line.
I have a full system with decat headers and removable baffles. The performance is exhilarating but also with better economy when required. Best LC of the three I have had. Mind you it is also a basic but has 17” wheels, sports rubber and TTX Ohlins shocks and has been to see Geoff.

How much run out have you got at the rear or did you change the swing arm as heard a few differing opinions , any pics.
Oh was it a bought conversion or the adaption of wheels.
Nice , what was the conversion.and do the pegs touch down as it makes we wonder..

1250 Rallye
That looks great. Removal of the pillion handles, and a sport screen, would be the icing on the cake.
Could you lower the front mudguard, as it’s sitting very high?
Just wondering if anyone else has got round to fitting decat headers to a 1250?
if so what brand and any feedback
