DNA Motoring ZTL-25SS 16 Pcs 2.5 Inches Stainless Steel DIY Custom Exhaust Tubing Mandrel Bend Pipe Straight & U-Bend Kit, Universal Fit

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.

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 lh62 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.

Had to order two different kits to achieve what I wanted. But worth every penny.

Great affordable kit, I had plenty of pipe left over to do a second truck if I wanted. My only problem was I saw some flash rust inside the pipe. But it all welded up great

Nice pipe. Needs painted or coated though.

What can I say it’s exhaust pipe exactly like I ordered. Super easy to weld and then bends are pretty smooth. But like any universal kit prepare to do lots of cutting and welding.

This was the easiest exhaust kit that my husband has ever used each peace fit and the thickness of the tubs are great functionality was great amazing quality ..fit this to or 1963 chevy truck beautiful sound

Bout this to fabricate an exhaust for my son’s truck he was building. This worked great. Had enough mandrel bends and straights to complete an exhaust for a 95 F150 extended cab. Will buy again when I do the exhaust on my truck; if I ever get it built.

It doesn’t come polished but quality is there, will see how they last

2 long pieces of pipe not in package

Good quality steel, welds well, perfect slip fit joints. Highly recommended

Lots of shapes I had to cut and modify for my application but good quality and easy to work with
