Need Help!!!

[JAHORE]

K guys, i have an 06 ltr. I have the full yoshi (round end) exhaust, yoshi's pim, yohi's Fimak, and pro design air intake.
I want to set it up for sand drags, will 13th sproket in the front and 38th in rear be good?
Oh another thing, is there a big difference between round and oval end cap on the yoshi exhaust? I know one is newer than the other.

[LTR450_#67]

I don't know anything about setting it up for sand drags, but I can tell you the reason for the different endcaps on Yoshi cans.

The oval end cap is the older version of the Yoshi RS-5 exhaust for the LTR450. Well there were about a handful of guys having their LTRs catching fire due to the older canisters having a flaw of some sort having the end cap exit being part of the culprit.

So since those happenings Yoshi redesigned the RS-5 a lil claiming a power increase over the older ones, but the gains are minimal from what I read on other forums. Atleast you don't run the risk of your quad having a meltdown.
