DNA MOTORING ZTL-25SS-8P 8 Pcs 2.5 Inches Stainless Steel DIY Custom Exhaust Tubing Mandrel Bend Pipe Straight & U-Bend Kit, Universal Fit

Used this kit to make a custom exhaust for my datsun 620. Im not sure it is stainless, seems more lile a coating. Its been a few month and havent noticed any rusting. The bends were smooth , no press bends. It welded nicely with flux core using my miller 215.

I picked up this DNA Motoring 2.5” stainless steel tubing kit for a custom exhaust project, and it exceeded my expectations. The quality of the stainless steel is excellent—smooth bends, no kinks, and a clean finish that’s easy to weld.This 8-piece set offers a solid variety of bends and straight sections, giving you the flexibility to design just about any custom layout. I was able to cut, fit, and weld everything without issue, and the tubing held its shape throughout the process.It’s a universal kit, so it’s perfect for custom builds or swaps where pre-fab kits don’t quite fit. For the price, this is one of the best DIY exhaust kits out there. Highly recommend it for fabricators, gearheads, and anyone doing their own exhaust work.

Very easy to weld, has very nice bends and is sturdy for sure, holds up to heat and rust on my straight piped f250

Really nicely bent. Fits together tight but loose enough to turn and twist the pieces while interlocked. Def worth the money

Great quality! Slightly loose fitting but I'm welding together!

Wish it had just a tiny bit more but made it work for LS400 from O2 sensors back

Better than expected

Great product, arrived fast and in his condition
