Q2 vs. 496
Posted January 21, 2006 - 08:52 AM
I need a quieter pipe/SA for my new YZ. I mostly ride desert & hare scrambles and am in LOVE with the power/throttle response of my new ride, especially low to mid. I hate to spend 400 bucks to loose it, but I gotta quiet her down.
Anyone know which one performs best? Which one is lighter? Smaller?

the new titanium power core 4 is supposed to be 100db (3 less than my old pc4) and you can get it with the optional 96db insert,which robs a little bottom end but will comply with USFS noise rules(for now),it is also spark arrested(or can be ordered that way) i think i'm gonna try one as soon as they're available anyone that puts a Q on a yz 450 and says it has plenty of power,probly just came off a ttr 125
I am anxiously awaiting to hear some opinions on this one too. I am in the same boat as you. I love the new YZ, but damn, its too loud. I know our WR brothers can help us out.

There's got to be a way.
This dyno graph http://www.fmfracing...oom.asp#honda20 shows a crf450 producing MORE power after 6200 rpm with a Q muffler. Would a Power Now help restore the bottom? I seem to remember Jimmy Lewis in a Dirt Rider story claim that their YZ450 w/Q2 was "nicer"(no thanks) for the trail, but the addition of the Power Now brought back some snap, and the second Power Now('tween the carb n head) was to much.
Am I remembering that right? Does anyone have that issue, and can confirm that for me?
FMF claims their new Megabomb header restores most of the lost torque associated w/ quiet pipes, but crikey, how much is a guy supposed to spend to be responsible?

The Q2 has internal baffles that cant be removed
The 496 just uses a longer canister than the T4, an endcap with about a 1" opening and a spark arrestor with like a washer welded in it. You can just take out the restricted sparky (or put in an unrestricted one) and change the end cap to a larger one (1.5", 1.75", 2" available) and you have some serious power unleashed.
I say go the procircuit, easier to tune, play around with and be quiet when you have to. Hell, I can make my Ti GP lowboy system very quiet with the quiet core insert and endcap!
