Long tube headers or downpipe?

Only need 1 thread for this. Please close one of them. Thanks! :tiphat:

I would suggest getting a BERK HFC / TEST PIPE if you are looking to get more power from your 370z.

Berk High Flow Cats 370Z/G37

These Berk High Flow Cats are great for the track or everyday driving. They provide great power increases, but still provide some emissions control and are slightly toned down compared to the test pipes. They are made using Full stainless steel construction and metallic substrate spun catalytic converters and are OBDII and 49 state smog compliant. Includes their custom made soft crush graphite collector gaskets for a leak free seal, which are made specifically for this motor by BERK.

Berk Test Pipes 370Z/G37

These Berk Test Pipes are great for any horsepower junky. They release the most power from your VQ35HR or VQ37HR engine by completely eliminating the catalytic converter. They features fully rounded connecting ends and plated support brackets, making them the strongest in the industry. Includes soft crush graphite collector gaskets for a leak free connection and a barrier to ensure pipe expansion due to heat will not pop open a connection. Made using full 304 stainless steel construction, and made the right way in the USA.
