Default Re: Custom Frame For Thumper Motor

More info chit on the thumper...this time it’s a new exhaust. My neighbors will be relieved.
This is my simple design which allows me to repack if needed. The result as far as sound, it’s now a nice deep tone till you jump on it…then it barks hard…

I plan on building one more exhaust…just need to find 1 in. tubing with a 4 in radius…good luck

Ya like Scotto said...what are you waiting for?
