Just ordered one the other day, should be here next week. I won't get it installed until spring though.

After doing some experimenting with my stock exhaust system and the Benz Silencer, I finally got it quiet enough for snowplowing around the house so I don't wake the kids at night or bother the neighbors in the morning.

The drawback I just found out a few days ago, was a huge loss of power at half throttle. I'm sure it was due to increased back-pressure, which I never noticed or felt while snowplowing, since most of that is done at about 10 mph. But I took it up the road to plow out a neighbor, and when I went to open in up a little, it didn't want to get about 25 mph without A LOT of throttle. This wasn't a problem before the Benz Silencer, which led me to a new muffler solution.

What I'll do is use the Stock/Benz set-up only for winter, and use the Supertrapp for the rest of the season. Being that I have sensitive hearing, I'll probably end up wearing earplugs while I ride with the Supertrapp, but hopefully it will be quiet enough that it won't be a huge issue.

When I get the Supertrapp next week, I'll take some pics of it inside and out, so you all can see how its constructed, etc. As of the day I ordered it, I could not find any pictures anywhere that showed the internal construction. I suspect it's much like the IDS2 with quiet core, but I'll find out for sure next week.

is this going to have the tunable removable disk on it or it it a regual style exhaust. i know on my vmax i ran it w/ the disk style and could change the sound and perforcemance by the number of disk on the exhaust.

Keep in mind that most aftermarket systems produce power in a narrower band than the stock system. You probably are aware of this but posted just in case.

06 Hawkeye - Factory Stock - performance great.

My 800 had the best performance from the factory dual muffler set-up. Revved very freely, no flat spots, ect.

When I switched to the factory single muffler set-up, I noticed a slight reduction in power. Now with the Benz attached to the single muffler, is has a huge flat spot in the midrange, which is exactly where I don't want it. If all I lost was top end then I probably wouldn't even notice it, but losing power at 25 mph isn't going to cut it.

Stendori, the IDSX is an internal-disc (tuneable for sound and backpressure) style.

If I get the same performance from it as I had with the factory duals, then I'd be extremely satisfied.

well if its anything like the ones i had on my bike then the more disk you put on it the louder it would become. also theres a cetain of disk you can use before regetting on a carb but maybe it wouldnt needed to be remapped on our efi's.

I don't have this mounted up yet, but thought I'd post some pics on it.

This pic shows that the cannister/ body of the IDSX and stock 800 muffler are the same length.



This pic shows that based upon the mounting point, the IDSX will stick out farther to the rear of the ATV than the stock muffler does.



This pic shows how the IDSX cannister's body has a slightly smaller diameter than the stocker.



This pic shows the mounting point of the IDSX, the welds are clean and seem pretty solid.

According to the description in Dennis Kirk, this muffler retains the stock decibel level. I'm anxious to find out!

Just mounted it up today. With the minimum number of discs (8) that Supertrapp recommended, its definitely louder than stock but the performance is back for sure. I'm going to take one disc out and see how it sounds.

I'll post a video with sound when I get a little bit more time.

With seven discs it runs perfectly. Slighlty quieter than 8 discs at idle but seems the same noise under load.

Without being able to actually ride it on trails yet, I'm satisfied so far with this muffler.

There's another video on youtube of a guy with an 800 and HSP muffler, which is quite a bit louder. The Supertrapp seems mild compared to the HSP.

Yes, the discs are inside. They sit about 4 inches back from the outlet.

I noticed in the video it looks like the muffler moves around while the engine revs up. It only has one mounting point compared to two for the stock muffler, so obviously it is more flexible and can move around a little.

I'm done messing around with mufflers for a while. I put the 8th disc back in as it seemed to run better than with just 7, and it is just too loud for me. Supertrapp claims that it maintains the stock decibel level but it doesn't. While it's not overly loud, it's still louder than what I prefer. I have the stock muffler back on there now.

So I'll be putting it on Ebay this week.

It only has about 10 hours on it if anyone is interested.

I mounted up the exact same muffler on my '07 Hawkeye. I will say it did improve the low end, it did not cause any loss at midrange. It has much more "grunt" than it did with the stock muffler. I haven't been able to fully open it up yet, so I can't say it has helped the top end any. That wouldn't bother me any since the Hawkeye is no sport quad anyway. I used 10 discs in mine since I have a DynoJet kit installed. A much deeper throaty sound at idle, no big difference other than that as far a sound is concerned.

All in all, I'm totally satisified with it on my quad.

I thought I had found the best price. You beat me by $10.
