these just might be the exception so you might wrong...seems V&H went to great lengths to design the best muffler ever specifically for the M8s taking all aspects into consideration
when they were introduced Bryan from V&H came on here and was grilled pretty good about the large baffle and torque loss and I recall he upheld their position that the baffle design was the key...I was one of the ones to challenge this but agree, seems nobody would recommend that big of a baffle for most touring performance bikes..be interesting to hear pro feedback now that they have been out for quite awhile

did you ask them, and did they say..they have actually ran tests on these? we have V&H saying one thing, and Painted Pirate in real World use states he feels he regained lost torque from his rineharts after installing 450 torquers....if I were looking at OEM replacements I would stick with 4" muffs

Not calling V&H liars... I am just going to put my faith in FuelMoto (who does not have a dog in the fight) to steer me straight on what I should do.

yeah but how many manufacturers make 2.75" baffles in 4" mufflers? don't matter, I'm also in the same camp of less is more for Touring bike performance anyway

Correct... its about baffle size and if fiberglass wrapped or not.

All I have for my personal experience from running DBX and TQ450 is my butt dyno, I'm not too interested in the numbers game. My 114 had the HD Tuner, extreme ventilator and HD's Torque cam stage two when running both the Rineharts and V&H slipons. Immediately noticed a big dip in off the line, 2k-2.5k -ish RPM and throttle response diminished a bit with the DBX 4.5. Swapped out to the Torquer 450, did nothing else, the issues went away and the bike performs like it should, stump pulling power at any RPM and snappy throttle response. Again, that's my experience.
