The pipe that i have is a full system. I don't have any pics but there are pics of it on a DS on CT racing. The fit and finish it real good and it has held up real well so far.

Dingo2,
Sorry I can't help you - I've got the end caps; I just think the HMF - at least for the DS is a good pipe. How long has your friend had his mounted? I've heard the silencer packing should be checked if the pipe is loud as the first, cheapest thing to do. I do recall READING a post that the quiet core worked and also took away much of the power with it, so perhaps it was not installed right? (I have -no- idea if it is something that can even be installed wrong.)
I agree that we are getting the short end of the stick on exhaust performance / sound performance. Why can't we get quiet, powerful exhaust as well.
You might look into the LTE dual exhaust, it is supposed to be 96 db I believe, though it takes a little extra work to install; as well as costing about $700.
DSaholic,
Not to sound stupid, but the last report on the CT Sonic pipe I saw rated it at about 106 db, which was the loudest pipe available at the time. (Probably in 2001 or 2002) Do you have a newer version of it? Discs do make a big difference over an open pipe, but I never saw a big enough change to be excited about after initially installing them. On my 1987 Mojave, I tried everything from 6 to one disc, and only saw a slight change in sound with a huge change in performance (the engine REALLY did NOT like 1 disc!)
DSengineer,
The CT sonic pipe that I am aware of is a full system with headers etc.

Well I went from a MBRP race system and the CT is much quieter. Like i said I have never had it measured but it is quieter than my buddies that one has just the end cap and the other has the graydon open end slip on.
I have never had a problem with sound as I ride in UT and ID mostly with one trip the sand mtn NV. It does come stock with a USFC approved spark arrestor also.

Other than your ATV being beat to heck, why can't you run the LTE?

Oh yeah, I forgot about the filter thing with the LTE. Too bad someone doesn't design a way around that, but then I guess that would be up to LTE, or a keen distributor.
