Default source to buy exhaust pipe

Well the last kit bought had 45-90- and straight piping. It was stainless steel, and I thought I was just a terrible welder but now that I have welded enough stuff, Ive figured out that the stainless is junk. Id be weld a pretty decent weld then all of a sudden poof- Id have a big hole to weld up. I necessarily dont need stainless so just good piping if it will withstand dp temps. Any source or brand you would recommend. Yes, I have a couple of local muffler shops but they kink 90 degree bends and dont carry any 3 inch. Thanks

Hack out factory exhaust bends from the junkyard or go to ebay/amazon and read the reviews. Your are taking a risk with ordering it, but it's the way most of us do it.

This place has a good rep, but I've never ordered from them:

I guarantee you are welding too hot. Many of you guys post pictures and I just have to chuckle. Its just exhaust pipe after all and you're trying to weld it like its 1/2" steel. Top quality ss piping is not cheap. There is a reason custom exhaust setups cost so much.

I use SPD Exhaust. That stuff is really nice and is ready to weld. Walker/Dynomax is pretty good too: 16ga, mandrel bent, readily accessible, reasonably priced and made in the US but you have to clean up the coating before you can weld it.

That is an understatement.
SPD products are some of the best out there. Their 321 is wonderful to weld. It’s so clean.

i built myself a cheapo hf exhaust/pipe expander so i didn't have to start learning to weld on butt joints and it was a godsend, for anyone just getting their toes wet. its a lot more forgiving type of weld to make and, fwiw, the expander works even better when hooked up against a powered unit vs hand-pump.

What alloy s/s are we talking about? {cheap-409 or expensive 304-316 or321?]. I made my exhaust for the V8 Wagon in'91 out of 304 s/s, other than a little dirt it still looks good,340K miles later.

I like mandrelbendingsolutions. 200 bucks for a 3 inch 409 stainless builders kit, they do both expanded and non expanded ends. I've only used their aluminized steel kits though.
I don't know what I have

Ace Race Parts is also a great resource, especially for V-band assemblies and the like.
I spend a lot of time around race cars. A lot.

1975 245: Pea green, kinda rough. B234 swap (rebuilt, balance shafts deleted, H-beam rods), Hy35, KLRacing header, external TIAL gate, NPR, shortened stock intake manifold, Link G4+ Monsoon ECU, T5 WC, front coilovers on raised strut towers, and a never-ending, ever-expanding list of dumb ideas

8v B230F w/ HX35, dual plenum manifold, full Megasquirt 3 ECU and harness w/ all sensors, just looking for a shell to put it in.

Burns is also having a sale on blemished bends, worth asking.

I have bought Squirrely Performance SS Mandrel bends off Amazon - decent quality. I agree with white855T - you are probably running way too much amperage on the welds. SS you can easily weld at 15-20 amps with a TIG - that's what I do & my welds aren't great.
