Default new exhaust WOW!!!

I just build a new exhaust for my 70cc HT. I started with 3/4" metal electrical conduit then went to 1". I cut wedges out of the pipe where I wanted to bend the pipe. then I welded it all back together. I added a pocketbike muffler ($20 delivered) and it sounds AWESOME!!!!! I get about 4-5 mph (on bike computer) more speed. The outlet for the muffler is back behind me and away from the back wheel (not getting on my back rim and on my rear brakes. Thats a good thing.
I hope someone else will benefit from my post because it reall was cheap and great for performance.

Once you have picked the forum you would like to post in....

Up on the upper left you will see a sprocket that looks just like the "reply" sprocket.

Except this one will say "New Thread"...click on that and enter the title of your thread and type away and then hit "submit" at the bottom.

Need any more help let me know

I took some pics of the new exhaust. I can't seem to post them. First it asked for the URL. I have them on my computer. Then I tried to attach the pics and it said that the files were to big and I don't know how to resize them.
Any pointers??
