You can weld with em nice. Ran my truck with a connector pipe to my cats from the header and they have so far held up. Will see long time review. Will be back to do so. A little thin though but still nice. Headers, this and then cats. And they make nice sound. You can hear the valves through the exhaust anlittle bit and I like that. Makes it sound stock car ish. I would imagine others would find the loudness annoying though. Will be finishing up full true duals here soon with a dual in/out connecting muffler soon. Just have to finish the old girl. 07 silverado lh6 2 month review. They're still holding up with blue demon flux core stainless wire. No gas. I ran some 308 rod on it as well and they weld nice. Must run 43 amps with the rod and run fast. Don't hesitate or you'll blow through. With 308 blue demon flux core wire. I ran it at 19 with 275 wire speed and yah gotta run that fast too. Don't hesitate. Weaving tiny circles as you move quick helps wet the toes better. But you don't need to. This runs better if u run it like a stick welder. Mig with 90/10 argon/co2 prolly woulda been best. But oh well. First time running the wire. Wanted to try it out. It's worked out. However long review. Months later. Exhaust hasn't rusted as I popped it with acetone and welded with proper wire. I need to redo the flex pipes and I may have em too tight in the exhaust and they're breaking apart a bit. Otherwise has held up very well. Still sounds good since I did it almost a year ago. Has the desired rumble. What's nice about this tubing. Is if u need to open up a hole for o2 Porta. Just put a dot on the spit and hold it there with the welder til it pops through. Makes an almost perfect circle and then you can run a step bit to open it to the desired size for bungs and defoulers. Quite nice. I'm going to be redoing my entire exhaust here soon as I had alot of blow through but I finally bought the proper gas and solid 308 wire to do it with mig weld tacks when holding in place and then I'm gonna tig it out. Finally got a decent welder instead of the easy flux titanium from harbor freight. Which welds nice but doesn't do everything I need to do. Still good to pull around though. I got the titanium 140 multiprocess and it works good. Not amazing. But can be fine tuned to be adequate. I'm a professional pipe and tank Welder. I can recommend this tubing and that welder.

Very nice bends and pipe, the flairs though are all too big so the pipes don't fit tightly, fine if your mig welding them but you can't slip them together and tig weld them. But I will continue to buy as the value is so good

This pipe is thick enough to TIG weld hanger to easily and thin enough not to add unnecessary weight. All the bends are very accurate and the pipe is not crushed at all. It was more than enough to do my entire dual exhaust system, even the tips, with some left over. I'm very happy with it. The size is perfect over the entire length, even the bends. Worked and looks great, I would buy gain.

It works. I used this to build a custom system for my truck, started off great, biggest complaint is that it rusted hard within a month of being on. A little disappointing that it degraded that fast. I ended up putting some high temp paint to prevent further rust but just hoping it will last. Other than that it’s been a wonderful kit.

I was thinking I'd receive dull steel exhaust tubes and was prepared for it. But the exhaust tubes appear to be aluminized and are very shiny and nice looking. The fitment was perfect between the flared ends and the tubing. The welds came out great and the exhaust looks amazing even unpainted. This kit has more than enough parts to complete an exhaust system.
