Hopefully you get the idea of this. It’s not obscene and if you want more then I can do another this weekend.
That sounds ok. Not what i thought it would be like. Do you think the bike might run a bit lean now. Have you riden it yet. ???
I rode it yesterday for only three miles just to check nothing would fall off, seemed smoother to me but that might be a mental thing, hopefully when the weather gets any better or dry I will give it another longer ride.
I take it the exhaust valve is gone. You will know if its lean when you get up around 6-8000 with it pinned. Once did a old rf900 exhaust. Ripped the insides out of it & it sounded great but flat as a fart hi up. Dyno jetted & went great after that. Same with gsx1400 made my own cans & same result. Fitted a dyno jet underseat adjuster & again cured it. Obviously with mutley its a different case. Bet you could get more out of it with a session on chip tuning. Whoever does them. I was lucky as the termi came with upmap & that transformed the bike.Good luck. Hope it all pans out. Steve.
Exhaust valve is disconnected and open, goodness knows what the weather is going to do but for the minute it’s sat on my optimiser in the garage, hopefully the weather might give me a chance to rip it up the road.
Mines been sorned since mid november. Too old for cold. Heater in van on full. Take care bud & keep posting results.
Did an hour on the bike this morning in the sun, love the sound of the exhaust even more, not offensive but for me just the right noise to warn others I am a coming up quick, gave it a bit of a handful at one stage and no hesitation in accelerating in fact it seemed smoother but that may be a mental thing going on in my head. So far so good.
Ok so after a few rides I can conclude, it’s not offensive noise wise, but it has made the bike smoother low down for example I can now go round roundabouts in second gear with no snatch’s throttle, third gear if I am a little quicker, I reckon the acceleration is smoother as well, overall I am a happy person with my project.
Hi Alan , I'm contemplating doing this to my 1260 exhaust. How did you know the cat was in that position in the box.
I didn’t, it was a logical thing taking into account where the pipes came in and exited, I cut to much of the case to start with (see post) so look for the tell tale signs on the outside of a weld, then cut above that. It’s simple really.
It is isn’t it, that internal cat is pretty solid when you start to break it up. Now get it welded back up and fitted. Make sit better.
Going to be welded back up tomorrow so will be able to road test in the afternoon. What's with all the sand or something that comes out as you beat the crap out of it
I guess it’s part of that cat thing, swept it up and chucked it away. Combined with the flap thing removed in the exhaust it makes the bike better.
