About Hyundai Genesis Coupe

The Hyundai Genesis Coupe is not the most popular car in Hyundai's lineup, but it may be a good choice for someone who likes sporty vehicles. It isn't too expensive either. This car model has a pretty sheath and has a front fascia that looks aggressive. The Hyundai comes with leather seats, dual-zone climate control, power windows/locks/mirrors & 6 CD changers. The Hyundai also has heated seats for both the driver and the passenger, Bluetooth phone hookup (and radio), and XM satellite radio.

Unlike your typical headers, the x-pipe will give you a little more power over standard pipes. Plus, it is easy to install any of these four cat-back systems on the Hyundai Genesis Coupe. You do not need to make any major modifications. The X pipe goes into two mufflers. These mufflers come in different sizes, like small and big, and the length you choose. But most trucks run short and large resonator models. When it comes to the Hyundai Genesis Coupe (2nd Gen), there are a few things you can do. Suppose you want more power and better fuel consumption. In that case, we definitely recommend adding a sports exhaust system so that the same 2.0-liter engine will breathe better and leave no opportunity unused to let out as much power as possible. Today, we bring you four cat-back systems which will provide extra juice for your ride at not too high price tags.

HKS 31021-KB001 Catback exhaust

The Legamax exhaust system is HKS's latest design. During R&D testing using race cars on test tracks, it was confirmed that the Legamax design allowed the engine's power to be more easily transmitted to the track surface compared with other exhaust designs. This performance permeates everyday driving conditions irrespective of whether one uses their car for exercise or business purposes.

HKS 31021-KB001 Legamax exhaust system

Made in lightweight 600 series stainless steel, measuring 60mm (2.36 inches) along the centerline of the pipe, Legamax boasts scooped sidewalls with brushed surfaces to improve flow and reduce back pressure while reducing exhaust gas temperatures for increased engine performance. Get out like never before when you drive your Hyundai Genesis Coupe 3.8L - 2JZ-GTE away from traffic lights or race down your favorite winding roads with this high-quality Catback system by HKS back there.

The HKS is the best exhaust system for you if you're looking for a sporty and aggressive tone; it's not for those looking to keep things subtle. The deep sound will give your car a singular character and make people turn their heads when they hear it. This center pipe, together with the muffler and downpipe, produces a strong and stable sound thanks to the maximum 60mm thickness of the piping, made from high-quality T409 stainless steel. Moreover, in order to maximize performance, there are expansion chambers that reduce back pressure while increasing turbulence inside the chamber through four merge collectors.

The Legamax by HKS High Performance is based on the popular 300ZX MAFIA's design. What makes the Legamax Premium different from other headers is that it has an equal length merge collector (gear-like shape near where you attach to the stock exhaust manifold) and what HKS calls a center pipe' side by side 3' style. This enables more efficient exhaust gasses scavenging than most single or unequal length merge collectors on the market today. The pipe size and angle of this large diameter 60mm piping measure right for maximum performance at 8000 rpm without chucking out too much.
