[QUOTE="Hick, post: 149081, member: 19514"] [b]Re: Really Expensive, Large and Chrome[/b] I have had a Q on my ’01 YZ 426 for about a two months now. It did seem to richen things up a bit. It is definitely quieter, no question about that, this is especially noticeable at lower RPMs but it is probably more pronounced with the throttle open. I have tried the stock can and the Q back to back on one occasion. I think the Q does steel some power down low, but it really shines up top. IMO it revs just like the stocker, maybe even a tiny bit better. I wouldn’t be surprised at all to discover the peak HP is the same on a dyno. But I do think it robs a small, but noticeable, amount of low end. I paid $290 for mine, but that is still too much. A two-stroke pipe seems more complicated to build, and is much cheaper. I recently had an entire exhaust, from the catalytic converter back, installed on my truck for less than what I paid for this pipe. I just don’t understand the pricing on these 4 stroke exhausts.... If I didn’t need a SA I would have just left well enough alone. But I am happy so far with the Q, and given the relative price of other systems would say it is worth the extra twenty (forty??) bucks. Finally, I have heard of problems sealing with the header, but this seemed to occur on 400s only. I think the 426 header may be larger, because mine fits very snug and does not leak at all despite what must be more back pressure than stock. [/QUOTE]
