I believe I've seen the same data as you - there isn't alot out there; Without getting bogged down all I'll say is that I believe any decent silencer (Lexx, LeoVince, Q4,etc.) offers a bit of an increase in the higher ranges without any negative effect in the lower rpm ranges.

2 cents,
Dave

I am not a fan of loud bikes at all, especially those that rev it up as they go by your open car window, not mentioning any particular riders of course ( cough.....hardly davids......cough).
My Hayabusa had M4's when i bought it, they lasted about 6 seconds before i was installing the stock cans. No need for weight savings on that bird at all.

That is my thought as well, just the weight savings on the KLR. I bought the Q4 and power bomb for it, read that it was the quietest of the aftermarket pipes as long as you keep the packing in good shape.

As to, weight-saving, a few pounds to a 400+ pound motorcycle won't produce significant handling improvements, nor mass reduction, seems to me (a half-gallon less fuel in the tank will do the same weight reduction).
I honestly dont think anyone really believes they add more power, they just sound like it. As you mentioned they may rob power. Hoping that with the KLX jet kit i can just keep close to stock power.

Yes 6 or 7 lbs does not sound like much but it is almost a gallon of fuel and when one is on a long road trip loaded with a full complement of gear any weight saved is a plus in my book. Certainly going to carry all the fuel my 6.6 IMS tank can carry and more than likely too much gear. Lol

Just my thoughts

- The Q4 is around 96db which is quieter than many of the aftermarket silencers and is trail compliant here.....but it isn't the quietest; that would be a tie between the LeoVince X3 and the Lexx with the trail insert - both are around 94db. I have a Q4 on my 2001 and a LeoVince on my 2000....the LV is noticeably quieter.

- Your Q4 will NOT cost you any power and you'll get a small boost with it plus the KLX kit (make sure you pull the snorkle as per Eaglemike's recommendation).

Cheers,
Dave

Agreed; many will say that the weight saved is negligeable but it all adds up. I'd rather carry 7 lbs of something useful.

There is nothing quieter than the stock muffler. But, you might quiet it a bit more by welding a 'turn-down' tip of the same size pipe onto the existing tip.

interesting.... I will look into it. I want to use this bike to do scouting(So I don't beat the 1 ton up on the back roads unless I have to pull an animal out).

The KLR Is perfect for the task... I can legally take it down the back roads roads... then punch out down the cut lines into areas that I want to scout on foot.. but not walk 10km to get to from the MSR.

I hate to say but,,I started my pipe mods by taking out the tweeter center tube,,sounded a bit better but still kindof sewing machine like. Then I saw a vid of some guy who cut open an entire klr stock exsaust,,and I couldnt believe how choked the flow is at the back of the pipe. Looked on the web a bit and saw a vid of a guy who installed a glass pack from the connector back 1/2{next to rear brake fluid tank} and it was a nice sound,,but will he burn valves? Sounded like a Ducati,,nice low thump rumble.Im thinkin of tryin something similar
