**You will obviously be able to alter the length and thickness of the pipe, buy additional pipes. Or not make a muffler like I did. You cant do without a Welder or a Grinder.

***Tractor Supply sells thread in mufflers, you can also find them on ebay.

****The rainbow effect only works on thin steel that is heated up to 600 degrees.

I am only a beginner at welding, I could have done so much more. Feel free to give me tips on my welding.


Depending on the application, this exact should provide a better sound, and more air flow. Leading to more torque and HP.

I Used:
1/2 90degree pipe
1 1/2 inch pipe
2 washers
