Jemini Power Performance was officially founded on 12/28/17. This business was created for the people of the Nissan Maxima and Altima communities. We have brought back the well sought after performance y-pipe for the VQ35.


We took the Racingline ypipe and revamped it to a whole new level. Racingline used bare materials such as mild steel, mild coated with aluminum and 201 stainless steel to produce the initial ypipe. We had it tested to see these results. Many people have seen the impact however of this down the road with rust and premature failure.
What we are now bringing to the Maxima and Altima community is far better. Top quality 304 stainless steel construction throughout that will not rust, all custom made gaskets for both header connections and 1 exit path, shortened .5 inches to meet oem specifications, smoothed u-bend from rear header, and a 2 year warranty.


  • Nissan Altima

  • 3.5L Coupe & Sedans, 6 speed and auto (2007-2015) SOLD OUT

  • Nissan Maxima

  • 3.5L Sedan (2009-2023)


  • The Y-pipe will not void any warranty under the Magnuson Moss Act. Read more here:

  • The Y-pipe does NOT eliminate the 2 primary cats on the Maxima or Altima 3.5 and does NOT cause any issues with smog or emissions.

  • The Y-pipe will NOT cause any check engine lights or codes as there are no electrical connections on it.

  • Installation is a direct bolt on (no welding required) and takes about 1 hour. See Install Guide PDF at the top of the page.

  • What are the benefits: Increased performance (acceleration and low end power are both increased), sound quality (much smoother flow from 1 inch to now 2.5), up to 2 MPG increase & weight reduction.

  • A new set of Gaskets and decals comes included with each Y-pipe.

  • Shipping is done by FEDEX from Las Vegas the next day once paid in full and i provide tracking information the second it goes out.


I am not a big major business with a bunch of sponsors, overhead, employees or communications breakdowns. I am CEO, CFO, all the way down to the Janitor. All communication is done directly with me. I am a Maxima owner of a 2011 Platinum Tech 30th Anniversary Maxima and have been a part of the Maxima community for over 9 years. I am a Moderator for several Maxima Facebook groups and take great pride in advancing the Maxima and Altima's potential. My customers are my life, and many become my friends. We build a great quality product at half the price of our major competitors because we are simply just a part of the community who has been blessed with this opportunity and who wants to get great parts into the hands of our members.
