the only thing about having the switch instead of a key switch is when you go on a Vincent Torres like a gopowersports.com somebody can climb in the vehicle and start it up and do serious damage to the vehicle themselves or others by putting the key switch on it it protects you from some liability

Have you ever drove a vehicle up that lean to the jump it off the top of the barn you would really get some awesome are but you probably also break your back if you tried it without having the proper shock absorption. Have an excellent day

If you stick a piece of aluminum underneath whatever a piece of steel you’re welding it will help fill the gap because there’s something underneath there but steel won’t stick to aluminum. And vice versa. That would’ve helped a lot with that mesh stuff for the silencer!

I'm not trying to put your welding down but I learned a good way how to TIG weld exhaust and I would like to tell you where I learned it... Look up Finnegan's garage he's on YouTube I don't know what episode it is but there is a guy who was a professional exhaust Builder and he does it tig welding I just figured you might want to check it out... I'm a welder and I think what they show on that is very educational towards TIG welding on exhaust systems they tell you to use argon to fill the pipe so that's an inside weld doesn't crystallize which it will if your welding stainless exhaust

I hate to say it guys but your exhaust placement is terrible. You are going to be burning off leg here continuously and slow roasting your leg fat. Should have probably ran it lower underneath of the vehicle with and 8 in thick piece of aluminum heat shield separating it from the passenger compartment.

That muffler i don't think will work like you are hoping. The exhaust needs to flow through the mesh pipe and packing. Basically you need a "S" flow in the muffler. Inlet has straight solid pipe going internally that stops a inch from the other side and the exit has the packing and mesh pipe. Need a divider wall that stops 2in from one side. You can reverse it where mesh and packing is inlet though.

Question! Is the exhaust going to be too close to the u-joint on the driveshaft? Won’t You be melting any grease that is put into the u-joint?

If you do end up making another muffler in the future you can make two strips to sandwich the seam of the mesh. Clamp it all together, cut down the middle of the strips then weld that seam back together. Might give you some more material so it doesn't burn through. You can even weld on the outsides of the strip as well for added strength.
Can't wait to see this finished!

You gotta get a gas lens kit for that tig welder. It looms like you’ve got a lot of heat and sugaring (tell tale sign of insufficient gas flow). Good luck! I love the videos!

Great tune! On the perforated part of the silencer extend the inlets and outlets in to the cambers. Let the extended pipes retain the perforated part with out welding. Great tube.

Should have merged them into an x-pipe for the O2 sensor and then merge them back out to have dual exhaust.

Pro tip for better welds on stainless. Use back gas to purge oxygen out of the inside of the pipe. If you look on the inside around the welds they tend to look crystallized and ashy. The welds might look ok, but they will crack easier without the back gas. Check out weld.com. They have some pretty detailed videos and good tips for beginner welders. Keep stacking dimes!! :)

A carrier bearing like they do on long drive shaft truck might of been a little better on ur guard. Wouldn't let shaft flop around if it broke plus would of gave some extra strength on bearing in transfer case and engine??

I was thinking or ask myself whybu didn't flange end caps on muffler. Usually packed muffler the ends are rivited or screwed around edges so u can change packing. But I figured u guys built enough stuff to know what u are doing and why

I really think you guys should have used steel wool for packing in the muffler instead of fiberglass. The way you guys drive and beat stuff that fiberglass will blow out and become an echo chamber

Try going to a number 10 cup it allows so much better gas coverage on welds and will help with color and heat. You can also get away with crazy stick out on tungsten for hard to reach welds.
