    I agree. I had an old Wes muffler on my KDX200 that I bought for it in 1988. It was about as long as a Lousiville slugger, and I actually had to trim the rear fender for the exhaust to clear it. It made the bike very quiet, as for smoothness, yes it flattened the powerband out and made the bike somewhat sluggish, and I thought it made the bike run hotter than it should. I recently bought a much shorter FMF universal muffler for that bike, and after I installed it, and started the machine, I immediately had to adjust the idle down. I expect the old beastie to run a little better down low, and run cooler now.

    Long muffler=more packing(little less DB)=more weight=more stress on mountings and sub frame=more restriction=different power delivery=more heat=shorter engine life.
    Why? maybe wanted to mellow out power delivery,make quieter? as Honda claims weight distribution for their twice pipes or just could be something new to sell.
    Easiest way to kill power of a good pipe is with crappy muffler.

    a little off topic- huge handling change made to my ex TE310 was the installation of the TC Ti muffler it cut the weight in half. and that weight is carries way aft of cg so over whoops the sprung weight forces were basically cut in half, or however the scientific formula works. LiFe battery with the muffler made the bike feel soo much lighter in all riding regimes.

    Are we balancing aircraft? If so remember that sliding the CG aft will reduce some slow speed stablity, but makes aerobatics much more lively. Sliding the CG forward will make for a better slow speed end of the envelope, but your aerobatic capabilities will become somewhat diminished.:lol:

    I really was serious. do the math @8 lbs bouncing through whoops at 35mph, or grab 8 lbs (@ weight of OEM TE silencer) and cycle it up and down/stop and go, then do the same for 4lbs @ 1/2 the weight. Think about how much force especially going down is put into the rear suspension and the leverage of that force being so far aft on g outs etc. Don't know about most riders but for me the feeling was instant when I added the Ti exhaust (that I got from cafe's Jake M) the rear was so much nicer even in side to side movements. As I said that along with the LiFe battery made the bike handle "that" much better. My 2011 TE310 is still right up there as the best most controlled handling bike I've ever owned (full boat/all the bells and whistles RaceTech suspension with ZipTy Racing service and updates on top of that helped too). PS I don't do aerobatics unless Im crashing!!

    I get it, couldn't help poking a little fun. Trust me I know the advantage of removing the stock Fiat muffler from my 449 and switching to the TXC Akro. Huge difference I felt right away. That and an Earth X and I went from hoping I wouldn't hurt my back to being able to easily pick it up and put it on a stand

    Guess I dont understand why a "long" silencer with there is a screw to adjust the p/v?

    And if the silencer is seriously 4 lbs heavier there is no way i would use it.... tons more stress on subframe, weight really high plus leverage on rear suspension.... Not that big of a deal on Jarvis bike, for the most part he races and rides slow speed trials type stuff...

    This is on the FMF page: Saw an article in Dirt Bike about a gayTM 300XC getting the full Stillwell treatment. It had this AND a new FMF Enduro Extreme pipe on it. Neither of which are actually on the FMF page yet.

    They've gotta make up for all the R&D cost they are dumping into 4t pipes by charging more for recycled 2t technology.
