The Infiniti G35 Sedan gets a big boost in performance with the addition of STILLEN's new Cat-back Exhaust System.

This exhaust presented us with a decision. The first prototype yielded tremendous power but at a higher sound level than we normally look for. Our tireless R & D team has refined the exhaust to come up with one that is quieter than its predecessor without reducing any performance gains.

After speaking with a number of G35 Sedan owners, we elected to keep both systems, giving you the choice of how quiet or loud you want the system to be.

Generation 1 - This is a louder system than our G35 Coupe or 350Z systems and makes substantially more power than either of those.

Generation 2 - New and improved - Same great power now with a quieter tone. The original system yielded tremendous power but at a higher sound level than we typically look for.

Either generation of these Stainless Steel cat-back exhaust systems will increase your sedan's performance by 21-23 hp and 21-23 lbs ft. of torque - at the rear wheels! Twin resonators are employed.

These are a 100% Stainless Steel system with dual path piping and a single muffler system that uses STILLEN’s distinctive X pipe to promote exhaust scavenging as well as balancing pressure.


With only 4 pieces to install this system weighs in at 13 lbs. less than the stock exhaust and offers a precise fit on any Sedan trim level. Polished pieces include the twin resonators & muffler while twin polished Stainless tips finish off the system for a great look. Please note, ships in two boxes.
