Sadly, Yes! :banghead:
The 'tinny' noise itself has got
a bit to do with the lack of tupperware on these models (unlike earlier RT's

);
somewhat more to do with the exhaust & catalytic converter, the latter of which is basically just a heat generation device that adds a weight penalty; and
a whole lot to do with the design of the motor itself - it's a transverse, in-line, triple cylinder, 4-stroke, Dual Over Head Camshaft motor, so because of how it runs & fires those cylinders, it's pretty much going to sound
juuust a little 'tinny' regardless - sorta like a kid going berserk with a home-made rattle made out of an empty tin can half full of gravel, and nothing really helps disguise that part of the noise... :banghead:
If you want to change the 'exhaust note' a little - cos nothing will change anything about it
too much, aside from its volume

... then losing the catalytic converter can make the exhaust note just a little deeper, freeing up some top end grunt at the cost of a
tiny amount of low-end torque; or swapping out the muffler for something less restrictive can make it louder & often more obnoxious or harshly tinny...

Or you can look at the combined offerings from some of our sponsors, and maybe do both a cat-delete (to get rid of the catalytic converter, losing some heat & weight in the process) and fitting a free-er flowing muffler, possibly with a baffle or two (to counteract the extra noise output)?? :dontknow:
Lamonster & RLS Exhausts both have some good offerings, and there's a few vids on-line that'll let you listen to the noise output from the various mufflers/converter/resonator combinations - but really, to
some degree, that 'tinny' sound is going to be a part of the package whatever you do!! :bdh:
