The Infiniti G35 Sedan gets a big boost in performance with the addition of STILLEN's G35 Cat-back Exhaust System. This exhaust presented us with a dilemma. The first prototype yielded tremendous power but at a higher sound level than we normally accept. Our tireless R & D team refined the G35 exhaust to deliver a system that is quieter than its predecessor yet retains all the 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 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.

Perfect fit every time
Color: Silver, Size: 30W x 30L
These original 874’s are the real deal. Stocked up during the sale and got them for my husband. He loves all the colors and the durability of these pants is incredible. He still has some from 14 years ago! But he wanted a few new ones- and they had more colors so I stocked up and surprised him when I told him how much they cost during the sale. These pants never wrinkle. I wash them hot and air dry- no wrinkling or shrinking. They look great. They’re sewn to perfection. The quality is there and has been for years, a reason my husband only wears these. Quality, value, durability, style, fit. Great for all seasons, they’re not too heavy or too light. Great functionality- pockets for everything . Great even in summer - they are very breathable. Perfect fit every time. Great for heavy road construction or just going for a hike. Highly recommend!

Run small, size it up
Color: Mushroom, Size: 32W x 30L, Color: Mushroom, Size: 32W x 30L
They go small, Im 5'8", 165lbs, usually 32x30 fits just rigth in most brands Levis, Izod, whatever, can't even close the zipper on this one, my dingus prints in the front if I manage to close it, I will try a 34 or even 36, if you want one, size it up. Length is right. Anyway, the pant is good, sturdy looking material, is not soft but nothing uncomfortable probably gets right after break it in, reinforced stitches on pockets. I think they would work great for a technician, salesman or an engineer, those jobs where you have to look like a human being with a polo shirt but sometimes needs to do something without ripping your pants while crouching or for daily abuse of the regular Joe, will try another that fits
