It has both quietness and low exhaust pressure! It’s almost quiet as stock vehicle exhaust sound inside car at a low RPM drive. Once you step on the accelerator, you will have dry sporty sound.

Advanced Legamax with vehicle specific stylish tip design. Legamax Premium mufflers offer the performance benefits of a sports muffler with the class and elegance of a premium muffler. Every tail pipe design is customised per application to ensure that muffler has impact and becomes a focal point in the appearance of the vehicle, yet blends with the overall design of the car. Legamax Premium mufflers are constructed of SUS304 grade stainless steel to give a high lustre finish which is durable. Some applications also incorporate the latest automotive fashion trends by featuring titanium tail tips which adds to the premium appearance with its distinct look.

The concept is the "light weight". It will give you the sporty look because of the carbon wrapped tip. The weight gets half of the stock muffler. We made each pipe and silencer lighter. The appearance is aggressive cannonball design and we wrapped it with carbon at the tail. It is a pure sport muffler which has improvement in weight and output performance.

The Ultimate High Spec Muffler Designed For 1000ps.  HKS has developed one of our most powerful muffler. It's for horse power of 1000. It's for R35 GT-R with HKS GT1000 RACING SPEC. We purely pursuit the exhaust efficiency for super low exhaust resistance pressure. The RACING MUFFLER pipe diameter is 101.6 and didn't have to narrow down. It connects to the main pipe by changing from the 2nd catalyzer so that we didn't have to limit the diameter of the pipe because of the stock flange part.

HKS Exhaust technology, which is know-how of long time development, targets to pull out 100% engine performance with the exhaust manifold. A lot of different approach were tried for each vehicle to keep performance for middle rpm range and to improve horsepower at high rpm.

STAINLESS STEEL HIGH PERFORMANCE FRONT PIPE. Front Pipe decreases secondary exhaust gas pressure of turbine to improve response. Stainless steel is durable and good looking. Flanges are also made of stainless steel and tig welded that reduces exhaust gas friction.

A stock extension is designed to merge the main port (turbine exhaust) and bypass port (wastegate actuator) in turbine exhaust housing. This causes the exhaust stream from the main port to interfere with the bypass port stream when the actuator is opened. The primary and secondary exhaust pressure will rise causing the boost pressure to drop, which can cause a loss in power. The HKS Extension Kit will optimize the turbines performance with minimal power loss.

The fun to drive at will and the balance can be adapted from circuit to winding roads Raised Driving-Comfort, ❝Ultimate All-Round❞

To pursue a comfortable ride and more enjoyable handling performance.

～Obsession with High Quality～ Integration of quality over cost principles of tuning parts and benefits and compatibility gained from OEM design. Unlike most stock fitment type suspension kits, premium "ride comfort," "style," and "stability" are pursued at the highest level and realized by HKS in this product.

The most powerful intake system carefully designed to fit engine room of a vehicle. HKS Racing Suction pushes air intake system efficiency to the limits.

HKS provides "Mature premium sports with high quality driving" with Premium Suction Kit. Aluminum suction pipe and Super Hybrid Filter reduces intake resistance and enables quick response.

Carbon fiber was chosen for its high tensile strength and beautiful appearance. The twill weave emphasizes each strand of carbon and delivers a premium motorsport appearance. A Matte top coat is used to reduce unnecessary reflection and emphasizes the natural beauty of carbon fiber. The intake efficiency is higher than the stock, but is still compatible with stock engine management.

The size of the opening is about 10 times bigger than the stock. Normally the FRP products have the fiber marks inside, but HKS Air Intake Duct has a flat surface inside.

Employing newly developed Nanofiber Filter for the stock air conditioner filter replacement.

HKS PIPNG KIT for Durability Increase and Consistent Boost Pressure under High Boost Condition. Stock plastic or rubber intercooler pipes can expand or crack under high boost levels. In addition to this, stock pipes have many bends which in some places are very tight radius which causes much resistance and pressure drop. HKS Piping kits are made of aluminum for increased durability and safety. The pipes have been redesigned to decrease the number of bends and to increase bend radius to minimize pressure loss and flow resistance.

"HKS COMPLETE ENGINE - POWERED BY HKS -" is manufactured with all technologies gained through Gr. A, Drag race, D1 GP and TSUKUBA Time Attack motorsport racing history of HKS more than 40 years. Making the best engine requires good engineers and facilities. These engines are manufactured at the same facilities and by the same engineers who worked on racing engines before. Experience the true HKS racing technologies with "HKS COMPLETE ENGINE - POWERED BY HKS -".

The Pursuit of Maximum Camshaft Efficiency The concept behind the HKS camshafts was to produce something that the customers would be truly happy with. This sounds simple on the surface but this is something very challenging. When the development team looked carefully at the details, the ultimate conclusion they drew was to look at the core purpose of the cam itself (to smoothly allow air into and out of the combustion chamber) and a good cam would do this job for the maximum efficiency.

The Performance requirement from Head Gasket. As the cylinder block and head are not rigid body, when the Head Bolts are tightened, the gap between the surfaces and the surface pressure applied is not even across the whole surface. Moreover, due to combustion pressure and vibration while driving, the conditions are continually changing and the contact surface is being continually beaten. As a result, a good gasket must ensure that contact surface pressure is spread as evenly as possible and also adapt quickly to the ever changing gaps that can appear in the contact surface to maintain a good seal with good pressure.

For drivers who just need "more power and more torque", HKS have designed a series of capacity upgrade kits to suit each engines characteristics. Increased displacement offers more torque at lower engine speeds and by using the highest quality materials, the durability required for high levels of tuning is achieved. Nickel coated pistons which have strong anti-knocking properties combined with fully counterweighted crankshafts and high strength connecting rods (rods optional in some kits) combine to extract maximum performance from the turbocharger and increase torque.

This timing belts best suited for use with HKS Slide Cam-Pulley. Optimized belt strength for each engine application makes the Fine Tune Timing Belt ideal for use with HKS Slide Cam-Pulleys for high power/high RPM engine.
