Reviewer: Michael Faxox from VERO BEACH, FL United States  
They came really quick within a few days and were in mint condition. Also came with the o2 sensor extensions and great packaging. Welds looks great and the overall header is great quality. Definitely recommend ordering from here.

5 of 5 G37 ISR Long Tube Headers October 5, 2022
Reviewer: Quincy from Forest city, NC United States  
I was pleasantly surprised to the gains I picked up with these ISR headers. My previous setup I had hks exhaust, isr hfc, z1 race intakes and made 320/265. I switched over to these isr long tube headers and picked up a surprising 18 wheel hp over that previous setup. Car is now making 338/273! Money well spent! I only expected to make 10 wheel hp max over the hfc.
