THE SOUND

Removal of the heavy chambered rear silencer and replacing it with a lightweight F1 grade Inconel 625 X pipe, and fully bypassable lightweight Inconel silencers, sheds a significant amount of weight, as well as raising the pitch of the exhaust into a more exotic tonal range. Removal of the OPF and catalysts, and replacing them with either HJS motorsport catalysts, or De-cat pipes, opens the sound up significantly, complementing and accentuating the high-pitched silencer section, into an exotic scream. The Kline innovation rear valvetronic setup, means that the car can be driven in stealth mode with the valves closed, however a raw unhindered sound can be achieved with valves open Addition of our beautifully crafted F1 grade Pre Preg carbon fiber exhaust tips compliment the exhaust perfectly.

PERFORMANCE

Replacing the OPF with a specially designed silencer, removes the most restrictive component, without causing drone associated with OPF removal. Replacing the stock catalysts with 100 cell HJS motorsport catalysts, or decat pipes, and correcting the subsequent af ratios will yield up t0 20 hp.

Perfect & light weight divider
Color: Charcoal Gray, Size: 8 Panel
I really like this divider. I have it in my bedroom which is also where my "work from home office" is. The divider blocks my bedroom and dresser perfectly. It's very light weight and very easy to move.

Room Divider
Color: Beige, Size: 8 Panel
I received my 8 panel folding divider and realized that I probably should have just ordered the 6 panel one. But it is nice and sturdy and was already put together. I am very pleased with the product.

Great Dividers
Size: 6 Panel-120"W, Color: Beige
Love these!! Many uses. Simple, nice looking, sturdy overall. Well made. Bought to divide the unsightly storage area from the calm rest area in the basement. Also, these worked well for our garage party where the dividers let light and air in, though blocked the view of our party area from the cars driving by.
