I guess the difference is gonna be the length in the rockers judging from his two adds on Ebay..........

Got the set I originally received in the mail to him today and hopefully I'll be getting the correct set soon. Went over the wiring today and found a loose butt splice, totally rewired everything and used solder joints this time around. 1st time I let out the clutch she cranked right up and I rode her around the block as that all I had time for as it was getting dark and I still had a little tweaking I wanted to do. She ran good as far as I could tell, was expecting a bit more power but beings these aint but little 3hp motors I dont guess I'm going to get as much as I'm used too!! LOL! She did feel good though and at least I didnt wipe out like last time! LOL!

it takes a few miles and about two to three tanks run through some of these engines to get them loosened up a bit.

the stock exhaust hurt the overall performance a little, but if you port match the header to the head as best you an and drill a couple extra 3/8" holes in the end cap it helps .

I have my newest GT5 engine build singing right along nicely at 40-42mph running a slightly modified stock pipe like you have on your bike.

Glad to hear she busted right off nice for you, thats always a great feeling.

The exhaust I have on there is the stock one that came with the kit but luckily I bought two engine kits as they were on sale at the time I bought them! Beings I have two exhausts as I bought two kits I'll have to try drilling the 3/8 holes your talking about and compare the difference. Might try that tomorrow if it aint raining like they been forecasting alll weekend!

I might try what I seen the guy in this video do.........

that exhaust is an older style, I have a couple of those pipes, the newer ones that have the single nut to hold the end cap on are different inside, the outlet is larger and the baffling inside is different.

There is a tube that can be cut off shorter that will help the flow and along with two extra 3/8" holes drilled in cap it does make a difference.

Judging from the pics you've posted of your bike, the pipe on yours looks just like the one Im currently using on the latest GT5 engine I just got going and it has actually impressed me with how well the engine is performing with that muffler, these newer ones flow much better it seems than the older version like the guy in that video is using.
