  • Good Value

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.

  • Cheap but rusts fast.
Style: Mild Steel Size: 2.5Inch
Easy to cut, nice mandrel bends, comes with a bunch of pieces to build whatever you need but holy cow does it rust fast and this car is parked in the paved driveway and never sees salt. If you purchase this, buy a can of BBQ paint and paint all your pipes so it doesn't rust to pieces quickly.

  • Amazing kit for the price!
Style: Mild Steel Size: 3Inch
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! ... show more
