Bad customer service September 20, 2022 Reviewer: Fady   Came with bad welds on heads, they refused to help. Don’t recommend buying the lth from them.----------------------------------NISformance reply, as we told you in email they looked just like the other ones we have. They are totally fine and work as intended,  you expected PPE quality with  ISR prices. Was this review helpful to you?

Beyond happy with my order! August 19, 2022 Reviewer: Wilder S. from New Hamsphire   First of all I ordered these ISR long tube headers for my 370z, they arrived 2 days after I ordered them. I am very very happy with the quality of the headers and the hardware as well as the exhaust manifold gaskets which are solid sheet metal and not the cheap perforated ones. The 02 harness extensions are high quality and everything came packaged and protected very nicely . I love this company because they are professional and extremely promptly with orders. I highly recommend NISformance to all car enthusiasts.  And yes they even sent me 2 decals which I will proudly add to my toolbox and garage. Thank you all again. Was this review helpful to you?
