I’ve been going to King Muffler for the past 3-4 years for exhaust welding work on my Maxima’s. Took me a while to find decent place with quality work with reasonable pricing. Jose is the owner and does great work. Clean welds and great pricing. He’s a stand-up and reasonable guy. Not to mention that he works on Maxima’s ALL THE TIME!

Tell him that Eddy in the white Nissan Maxima referred you.

NISformance has officially released the highest performance Maxima/Altima headers! They are starting with an initial group buy and pre-order. They need a minimum of 5 orders per type to put that specific type into production. The group begins Feb 1st, 2018 and ends March 1st, 2018

Normal Price: $1,600.00
Group Buy Price: $1,450.00 (Includes FREE shipping)

Pre-order Here:

Ensure you select the correct type based on your year  and transmission type.

  • Type 1 = 1995-2003 Maxima
  • Type 2 = 2004-2006 Maxima with manual trans or 4spd auto 2002-2006 Altima 3.5L with manual trans or 4spd auto

  • Type 4 = 2007-2012 Altima 3.5L
  • Type 4.5 = 2009-2014 Maxima (should be same as type 4 but need to verify)

  • CNC machined for a smooth transition from exhaust port to primary pipe
  • 1 7/8″ Primary runner size
  • Equal length primaries

  • Fully TIG welded
  • Constructed from 16 gauge mild steel
  • Manufactured here in house

  • JETHOT color top coats available (additional charge)

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, this first production run lead times will vary depending on the number of orders.
