G35 Exhaust System

The Infiniti G35 Sedan gets a big boost in performance with the addition of STILLEN's new G35 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 G35 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.

03-06 Generation 1 - This is a louder system than our G35 Coupe or 350Z systems and makes substantially more power than either of those.

03-06 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.

2008 Generation 2 - Developed in line with the previous Generation 2 goal, great power with a quieter tone.

Either generation of these stainless steel cat-back exhaust systems for the G35 will increase your sedan's performance up to 18-20 hp and 8 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.

About STILLEN Parts & Accessories

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.

    I installed the G2 cat back exhaust on my 2008 G35X sedan about 2 years ago. This exhaust is amazing. Very high quality, sounds great and completely changed the appearance of the rear of my car. I also installed the the G2 intake and have had noticeable power and torque gains. I just purchased the high flow cats and can't wait to get them installed! Stillen quality is excellent. You get what you pay for and this is worth every penny.
