Which Exhaust System would be the best?

What do you mean better? Power wise you aren't going to gain much at all by going to be better exhaust. Maybe 1hp max. I have the HMF and love it. They are rock solid and create great power. The best option power wise out there is the dual can setup. They are incredible but cost a pretty penny and require a remote rezzy shock. But, for XC racing, suspension before power any day.

What ever became of the duels anyway?

HMF durable? are you guys smoking crack? I haven't had any luck with them, durability wise. Good power yes, durable, **** **** no. I think a hollowed out corn cob would last just as long. Oh crap, are you guys saying that compared to other pipes, hmf is more durable? Holy crap. I shudder to think how long the other pipes last. To me, a decent pipe should last a season before metal parts started falling out of it.

Here is the deal. I bought the HMF QRS. It worked great the first summer. In the fall when I removed it, some of the metal mesh inside was broken loose. I sent it back to HMF and they repaired and repacked it for $20. I think that is a great deal for getting your silencer re-packed. So far, so good. This year, second season, only a month or so into it, somethin broke near the rear that holds the center mesh thing in place. It didn't take long for all the packing to blow out. I posted pictures here somewhere for you guys. With races every weekend, I didn't have the luxury of sending it out to HMF to be repaired, which they would have done. Peterock talked to them and got them to send the needed materials for us to repair it here, without the down time. While waiting for that, I destroyed the whole pipe in the crash you are referring to. I don't blame HMF for that one.
The quiet core pipe C27 is talking about is the HMF sport I picked up to get me by while I'm waiting for a new HMF QRS to get built. An HMF sport pipe with a quiet core will not last, don't even bother trying it. It holds too much heat inside. If you have a sport pipe and just run it open, it will probably last longer, I don't know, I haven't tried it. I need to keep the db's down here.
For me, the bottom line on HMF is they have good customer service, their pipe works well to give good power and low noise output, but for some reason the insides aren't holding up. I need two of them so when one is being fixed I can use the other.
