Berk High Flow Cats for 2007-14 Infiniti G37/Q50 2008-14 Nissan 370Z [Z34] BT1407-HFC


Quick Overview

Get the most power possible out of your G37/370Z with these High Flow Cats. BT1407-HFC-MET

Sku # : Berk-Test-Pipes-HFC-370Z-G37-ER3
Your stock catalytic converters on your 370Z/G37 are the most restrictive part of your entire exhaust system. Replacing these with either high flow CATS or CAT delete pipes (Test Pipes) will give you a huge increase in horsepower, torque and throttle response.  Take a look at both below to figure out what setup fits your needs better.

As of January 1st, 2009, performance high flow cats and test pipes are intended for off-road use only in the state of California.

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.

NOTE: Mechanical CEL fix is also included, but on the 07-up HR motors it is less effective than the 03-06 motors.

Fits: VQ35HR & VQ37HR Motors:
