STILLEN'S new exhaust for the G35 coupe is the result of months of development and testing on the G35 and 350Z. Made of 100% stainless steel, the system features dual pipes, dual mufflers and a lifetime warrantee. It makes the most power of any G35 system on the market and fits like a glove. Test results on a G35 automatic yielded 13-15 HP at 5200 and 16-18 ft/lbs at 4400 rpm. This is the first and best full cat back system available for the G35. The power and mellow tone have to be experienced to be fully appreciated. Please note, ships in two boxes! When you order online shipping cost will show $0, we will contact you with an accurate shipping quote. Similar in design to our industry leading 350Z system.
