if you could do a before and after dyno of your pipes i am sure that would help you sell also

just ordered a set of pipes off pete at trident, very easy transaction and looking forward to getting them, my bike will finally have that sound it should have had in the first place

Spider - will be with you on DHL tomorrow

Review (cont.)

Okay, the extra baffle arrived and was a pretty quick job to fit to the existing exhausts (just insert and re-screw, mine needed to be tweaked a bit but nothing major).

Fired it up and while the noise was cut down a little it was still at a fairly 'anti social' level. undeterred i removed the outer and new inner baffle and picked up some more packing material from my local dealership.

I repacked the outer baffle (so it now sits snug in the pipe) and added packing to the inner baffle (so it also sits snug).

Once inserted i had a sound that's significantly closer to 'sociable' (i'd say it's shaved 1/4 off the volume) whilst retaining most of the character of the pipes.

(still over road legal limits but not by a crazy amount i think - thats a guess, i'm getting Db readers for all three levels done as soon as i can borrow the equipment). Anyhow, for those that missed it before...

and now repacked with extra baffle

Still very happy with the exhausts, i suspect i'll continue tweaking them after i've ridden with them on for a week or two but they're certainly versatile.

they still sound really good repacked and with the additional baffle, but they sound deep and mean without it

I can't believe the size of that license plate... Good grief Charlie Brown!

standard issue on black 'americas, stops them going _too_ fast. I'm thinking of upgrading to a smaller plate to get 2 or 3 bhp out of it.



going to continue experimenting with the pipes anyway and will record any progress i make. aiming to keep the really nice exhaust note but mute the volume - was going to experiment with a washer or some kind of butterfly valve.

anyone else got any suggestions for tuning exhausts?

(note :- i'm only persuing it out of a sense of dogged persistance not because it actually really needs it, the level of volume i've got right now is sensible enough)

well got my pipes off pete at trident today couldnt wait to fit them,i got into the garage and ripped the old ones off and proceeded to fit new ones all fitted in about 20mins,ive left the first baffle in the pipes as without there a wee bit to loud and the rozzers will be on me tail without a dought,but as they are they sound fantastic so i got me gear on and went for a blat around the village to see how many car alarms i could set off,quite a phew,so to cap it all off im over the moon with the pipes and the sound and thanx again pete first class geezer
cheers steve

Hey Spider, do you have the AI still in your bike at all?

I still have mine and i've noticed the exhausts now have a slight yellow sheen where they connect to the downpipes. This is the exhausts themselves not the headers which are still shiny and silver.

I'm pretty sure stainless shouldn't discolour so i was wondering if it was anything to do with me still having my AI in?

thoughts?

suspect i shed some of the packing on the way to stratford upon avon and back though, became a little louder as i put some miles on it - still sound awesome though.

Actually, Stainless does yellow when you add heat... My scepters have yellowed some as have my wife's epcos.... It just wont ever blue is all... Oh, and AI removed on both our bikes....

Ah, cool - i wasn't sure.

I assume removing the AI will slow this process some?

Ant

hi there jesterminute,i dont have the ai on my bike but the pipes have started to yellow a bit but i quite like the look of it and still geting use to the awsome sound from these,people to look as you go by and no excuses for car drivers not to hear you,and i to had to repack the first baffle as it tried to depart from the exhaust just needed to tighten wire up around the wadding,hopefully meet up at some time and we can compare exhaust sounds (bit sad) but thats the life of bikers
cheers steve

My epcos gettig goldish either that how it is with stainless steel

counting the days ray
