I have had a Supertrapp 2-1 on my bike for years now, which I absolutely love, and moreso now! Since I got the Supertrtapp about 6 or 7 years ago, it has always had a partially open end cap with 6 discs and has always run great, but just recently after reading a few supertrapp threads on some yank forums I thought I would try a closed endcap and some more discs, so I went and bought the bits and installed them yesterday, I took it for a ride and all I can say is WOW!! the difference is phenomenal. I now have a closed end cap and 22 discs and it is like a new bike!  Wont be able to stay off it now, riding it is a whole lot more fun again!

And you know the really good thing?  If there is a cop car around or something all I have to do is ride nice and easy and it is as quiet as a church mouse, but when I really open it up it comes to life and has a very nice crack to it, so it has the best of both worlds now!

Sounds good mate, has it increased power in the low rev range? or an all round power increase?

Got any pics?

Awsome Mate,

I am still running the stock pipes with baffels removed, By the sounds of it I would even benefit from the 6 disc system you were using.

I might look into it as soon as I pay off the gearbox rebuild thats currently underway. (bastard detent spring broke)

Cheers.

The pipes are actually a cheaper Aussie made Supertrapp imitation (outercycle in Melbourne) the original Aussie made baffle accidentally got squashed (dont ask!) a few years back but the pipes and muffler shell were still in great cond., so I bought Supertrapp guts and they fit straight in, because the pipes were made to take supertapp parts like baffles and discs etc. But I must say they were just about identical anyway, and there was no difference in performance whatsoever between the original baffle and the Supertrapp one.

G`day fxr, I had the dual open supertrapp pipes on my 91 electraglide which i bought second hand but owned for 8 years.
In this time the pipes never discoloured and always sounded great so the first thing I ordered with the new fatbob was the 2 into 1 pipes with closed end cap.
I have always wondered what the sound would be like if I added more discs as I have 18, now might be the time to bite the bullet and grab some.

I didnt get a piccy today 91, I got called in to work this afternoon and it was dark when I got home. Will try to get one as soon as possible.

Heres the pics of the supertrapp I promised you 91FXR. I took them today, it was very bright and glary, but you can still see most of what ya need to see.

 

 

Thanks Mate.
