The exhaust pipes for the Blade / Kinroad / Twister / Carter will not fit the SUNL or any engine that has the 2 bolt valve cover (at least not without modification). The pipe has a different angle at the head and the bolt flange holes won't line up.
D-Short i know its not a performance exhaust but maybe you could do something like what i did and others to.
i just used hacksaw cut tip off muffler then drill holes in the inside of muffler. seems to flow good with a nice sound.
i used a 12'' long 3/8's drill bit i got at tractor supply,i needed one anyway
with what i done and the uni-filter i went from a 105 main jet to the a 125 main jet sure made a big difference in the engine performance.

113N08-4-9(12-38).jpg: 3 Time(s) Viewed, 24.23 KB the red box's are holes through muffler, first baffle plate that holds the crap in it and the one in the back to. 12'' long bit just works perfect for this.
yellow line holes stop at muffler do to the U shape tube in the baffle and the other junk.

So do I drill the lenght of the bit on the red boxes only?

D-Short the yellow line was just to show you were those tubes were, you can drill more if you want. this is my second exhaust the first one i broke at the flange and had it welded.i knew it wasn't going to last so i played with it a little.i think now i had around 7 holes drilled through it.for me with that many holes i just lost to much bottom end power with that many holes,not enough back pressure for me.
so that is why i went with 4 holes all the way through
if you space them just wright you can put a few more in yours if you want,its what ever your looking for.
hope that made since

let me rephrase that, when i say all the way through.i mean through end of muffler and the 2 plates inside of muffler. my muffler is 13'' long, with a 12'' drill bit in a drill you only got about 11'' length,so if you keep it running nice and straight you shouldn't go through the side or were the muffler begins.
just thought i would mention this, maybe not everybody's muffler that might try this is the same length.
