The NM Hi-Flow Air Intake System
The 'Open-Air-Box' system gives you the abundance and unrestricted 360° of air source compared to OEM's sealed air box with flat filter and tube fed air source. During R&D, we installed temperature probes around the engine compartment and the gauge showed the inside temperature matched the ambient after vehicle speed past 20 mph. And by logging the Mass Air Flow (MAF) sensor also showed that open-air-box intake generated higher volume (gr/sec) of air going through the sensor. So when we had to choose between (a) cooler air at all speed with limited air source, vs. (b) cooler air at 20~ mph. with unlimited air source, the choice was pretty obvious.
Three Exhaust Systems are available:
[ ] Borla Street for a slightly deeper tone over stock with a mild cruising sound - Made in the US and backed by Borla's Million Mile Warranty!
[ ] Borla Sport offers a more aggressive tone with slightly more volume for those wanting a more 'sporting' sound - Made in the US and backed by Borla's Million Mile Warranty!
[ ] The Quicksilver exhaust system is similar to the Borla Sport, but made in the UK - Quicksilver makes high-end exhaust systems for all the European Exotics.
All exhaust systems are 2 1/4" stainless steel system with twin 4" chrome tips.
The Borla system installs 'downstream' from the secondary catalytic converter. This requires cutting of the stock system just behind the cat, where the Borla system is attached. The rest bolts right-in.
The Quicksilver system installs at the flange, eliminating the need for any 'cutting'. However it removes the secondary resonator.
BORLA Cat-Back™ exhausts feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere.
Each system is built from premium Aircraft-Quality T-304 Stainless Steel, an alloy superior to T-400 series knockoffs, to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.
QuickSilver's High Performance Lightweight Exhaust system offers more horsepower, a crisp sporting sound, unique twin 3" chrome upswept tip design that fills out the rear bumper, and an all straight-through design for optimum efficiency.
The tone at idle is nice and deep, similar to a Borla system. The QuickSilver system has slightly more volume throughout the rpm range when compared to the Borla. Definitely not loud or annoying, but a nice sporting sound.
