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

For the price of this kit it worked perfect! Could not be happier with it. I'm about a month in with a custom built exhaust system. It is headers back to Infront of rear tires on an 85 C10. Was able to make an x pipe and all. It sounds great. Welding was fairly easy, had a lot of complex joints to weld that were more difficult. It looks good, fit good! Would highly recommend this as an option for a budget friendly diy kit!

I mean, you can NOT beat this kits price for quality bends!! Everything slips together where it should, fitment is quality and nice no kink bends! Just wish they had had it in stainless when I ordered but otherwise EXCELLENT!!

For the price, pretty good buy. Nothing was rusted, and all pipes had a light film of oil to prevent rust. Couple coats of high temp paint and you don’t have to worry about rusting any time soon

Very nice set not thin exhaust pipe either welded beautifully i did custom exhaust work with this set and still have left over pieces thank you only reason for 4 star was when I received the box it was all damaged even nice size hole but nothing was damaged or rusted up as you see in other people have claimed to receive

Just as described, good solid exhaust pipe

3 star on the mild steel ones lot of surface rust and in the pipes bad rust and some out side and plastic had a lot of rust powder in them .returned then and got the stainless one a lot better so giving the stainless steel ones a 5 star

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.

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.
