Bike bandit is having a sale on exhausts and are listing the IDSX full system for the 650 at 258.
Questions
It is listed as a FULL system but there is a note that says all IDSX systems use the stock head pipe unless otherwise noted. But it is the only system Supertrapp lists as a Full system. Which is it? Full or partial? Confusing! Supertrapp's website isn't any clearer.
This system uses a quiet core insert. How quiet is it?
It also has a USFS approved spark arrestor. If you run it does it negate the performance benefits of the exhaust?
Lastly, SuperTrapp quality. I have heard or read quite a few people complain about the fit and finish of the SuperTrapp.

In short;
Anybody here running the IDSX?
Did it fit properly?
Is it reasonably quiet?
Performance?
Repacked it yet?

Thanks

 

It is a full system. My headpipe didn't fit well, had to modify it. Sounds great, not loud. The disc system IS the spark arrestor. You add more discs to get more flow, and a little more noise. I've got 12 discs in and it's still not too loud, not near as obnoxious as a stock 660 Grizz exhaust. Haven't repacked yet, have heard it's a nightmare. The performance is very good, but I would try the Nyroc mod first next time.

 

Just a little more info on the IDS-X. I did go ahead and buy it.
The fit and finish was actually quite good. Everything bolted right up with no modifications. Only issue and it has nothing to do with fit and finish is the end cap screws. They are stainless as are the nuts they screw into. Bad combination! I wish they had made the nuts carbon steel so that I won't have to worry about them galling. For now plenty of nickle never-seize may work.
Decibel wise with twelve discs I would have to say that it probably is only 1-2 higher than stock. Tone is different though. I like it better than stock.
Performance isn't earth shattering but there is a definite gain with the biggest being around mid rpm. 12 discs?
Looks like I am going to have to re-jet. With an open air box I was running the Kawi jets for 5000' 135 and 140. Plug check indicates that this may be a little lean now. Even though I ride between 6 and 7 thousand feet I'm going to go back to the 138 and 142 and see how they do. For longevity I would prefer it be slightly rich.
All in all I'm pleased. I didn't want to do the muffler mod because I ride in National forests and would have gotten nailed for having the screen removed.

 

The trick is to use lots of copper based never-seize on everything. That will reduce alot of problems down the road.

 

I dealt with stainless pipe fittings for years and their are only a couple of lubricants that will prevent 300 series stainless from galling 90% of the time and neither of them are suitable for the high temps of an exhaust system. Nickle does a much better job than copper but it still won't totally eliminate it. The best solution is change the screws to carbon steel. Looks ugly though.
