If you need a TF muffler, I think I have a good used one if you wouldn't mind trading away the LF's.

I have both but I was just wondering what the difference was. Well I guess I have to weld the pin holes at the mounting brackets and put the trailfire muffler back on. Now all I have to do is put the Liquifire back together.

actually the internal measurements and dimenstions for the 340-440 exhaust are the same as i have taken these apart they are turned to a broad range and not much for power.

the liquifire silence tube is 1 inch short than the fan 340 and 440 but thats the only internal difference...

the expansion cone rear is 12 inchs long the mid part of expansion is 7 inchs the front part of exhaust which is slow increase from 30 ball joint is 31/2 or 4 feet...i have to remeasure that part. the silence tube is 18 inches long to 19 inches long and has a restricter washer welded to the end.. after that is the baffles and final tailpipe which is 6 inch long

an example of a tuned pipe the cone is 12 inch the silence tube is 12 inch open mid part is 6 inch close of expansion is 3 inch long to 2 1/8 inchs from 3 inch from 2 1/8 to port of 28mm is 5 feetand must slowly decrease.

this is example of a single tuned pipe for a 440 engine (not a kawasaki) that has dual pipes.

aside from the brackets being in total different places on the exhaust they are pretty much the same. the power band starts at 4000 slowly increases to 6500 peaks and slowly decresses to 10000rpm where it drops like a rock

How does it decrese to 10000rpms make no sense from my perspective

What he is saying is that the powerband of the engine is at 4000 - 6500 and after that the engine does not make as much horse power.

So the clutch engages in the power band and starts the sled off and the secondary clutch keeps the rpms in that range during acceleration to have maximum acceleration and then when the secondary is fully shifted the engine rpm starts going up but the acceleration is not as good anymore to the point the sled is maxed out.

no the stock exhaust does with a non stock exhaust they go higher but you need better clutch.
