    • Pipes are very high quality for price
Size: 3 Inch
Honestly this was some amazing pipe definitely buying more, especially from this vendor. The pipes were as pictured shinny stainless and pieces fit well together and was super easy to weld up. I wound recommend to get pipe from any other vendor due to ordering other pipes and they were very dirty and cheap quality. ... show more

    • Beautiful finish
Size: 3.5 Inch
Pipes are beautifully finished and when welded look like they were part of a pre-built kit. Really excellent quality!

    • Works for my project.
Size: 3 Inch
Made my life easier for my exhaust project. Welding was good, cutting and strength and tube thickness is good. Strong and does not bend unless heated and then not easily, contains the noise of the exhaust well. I was able to make my own exhaust out of 3 inch stainless and save myself some money. Not a walk the park but satisfying results. ... show more
