Thinking about doing DE headers

The key factor is that you must also purchase a set of DE style High Flow Cats, OEM Catalytic Converters or DE Test Pipes. The 3-bolt flange on the VQ37VHR headers' collector is different in shape than VQ35DE. However, the Test Pipe portion, when coupled with the headers, matches the 370Z perfectly. This same can be said in reverse configuration if attempting to put 370Z headers/test pipes onto a DE-style 350Z.

The Momentum Headers are one of the best on the market. Other DE style headers like those from Tomei Powered and so forth are also equally impressive in quality, but have not been tested on a 370Z.

We were investigating a few ideas when we discovered the gains brought about by using the Momentum Headers and were impressed.
