Doesn't look like much from the outside but there's somewhat a bit of work inside of these. I'm redoing my catback next week with 2.5" stainless pipe, a true dual exhaust setup with an H-pipe.

After shopping around I saw these:

Apparently they'll help me annoy the fuck out of faggots, especially electric car drivers so I figured let's do it but fuck spending 400$, I'm a make my own.

So with about 100$ of 304 stainless I prepped all the parts:

I took very special care while shaping the internals, a hi-tech plywood jig & a ball-peen hammer later I had them air-flow concentrating thingamajigs shaped.

No expenses spared either, i recycled that 0.15$ plywood jig to help me bend that 18ga sheet metal:

Once I had all that shit tacked up inside i was ready to close it up:

Them fancy lips on the internals were to allow me to plug weld the skin on top of the core:

There ya have it, fancy stainless mufflers for my truck. Probably doing the new exhaust next week if I feel like driving at the shop at some point, we'll see.
