Good Value
Style: Mild Steel Size: 2Inch
Worked very well for my project. I’m very happy with the quality and thickness of the material. It welded nicely and looks great.

Good for Amateur DIY’ers
Style: Mild Steel Size: 2.5Inch
Worked good for my DIY amateur exhaust for my LS swapped 81 caprice. Doesn’t look pretty bc of my flux core welding, but welded good nonetheless. I should have used band clamps instead. Oh well. Easy installation, decent bends and I did it myself. Sounds decent with Flowmaster 2 chambers and the stock 5.3 with s10 shorty’s with the v band clamp. ... show more

Good value
Style: Mild Steel Size: 3Inch
4* because product arrived, the box was trashed, holes all over, the top ripped open and semi taped shut. One of the straight sections has a thumb sized dent in the middle of the pipe. But overall, besides the above mentioned, the product seems to be good quality and shipped pretty quick.

Absolutely perfect
Style: Mild Steel Size: 2.5Inch
I used this to make a custom exhaust for my rock crawler. I have a great ellis band saw that makes perfect cuts at any angle and I was able to make a custom exhaust. Obviously this is for the experienced but the metal rusts quick but its exhaust.

Mostly garbage, some sections were okay others were not
Style: Mild Steel Size: 2.25Inch
Unfortunately I bought these a while ago for a project and it's too late to return this garbage. The pipe looks good but the "weld"down the entire seam of all of the exhaust pipe sections that I got is absolutely horrible, terrible penetration. Most of the pipes started splitting in half when I cut them to size at the "weld" making them for the most part completely unusable. Another cheap garbage product from China that you have to take a chance with and unfortunately sometimes you lose. Will never buy these again. ... show more
