Group buy headers have been produced and shipped out!!!

Huge thank you to everyone that participated in the group buy. We greatly appreciate your continued support and patience. Without you these headers would not be in production today!!

*Update* We have completed all orders and production of these headers has ended.

Jigs for these headers have been made, Allowing us to cut down production times drastically. Wait times will be much less when compared to the initial group buy.

Material cost has increased drastically in the past year, despite this we are able to keep pricing lower then initial explications. Pricing for 2 headers and y-pipe is $1550 plus shipping (Shipping will not be charged until headers are completed and ready to ship).

Unbeatable price considering:

- They are equal length (best performance)
- Order includes two headers AND a y-pipe (if it was just two headers the price would be much lower).
- JET HOT coated, they are the industry leaders in high temp coatings.
- The only production headers that come with a 2.5" collector.

We tested these headers back to back against ebay headers. Testing was done on the same day, same dyno, same car, same conditions! This is a true back to back test!

We have not tested our headers against stock exhaust manifolds, that test would show very large gains.

First car 2004 Maxima w 2010 Maxima engine, 350z ecu stock cams. showed gains in midrange and top end. 10hp and 4ftlbs tq.

Second car 2006 Altima SER with 2010 Maxima engine with JWT Cams showed gains above 4000 rpm 14hp and 10 ftlbs tq.



We are a small Maxima/Altima performance focused shop. Manufacturing these headers in house, lead times will vary depending on the number of orders.
