Product Details

The HKS Legamax Exhaust System (33004-AF002) is an application-specific cat-back exhaust engineered to reduce backpressure and increase exhaust flow, delivering greater peak power and a broader torque band across the RPM range.

Each Legamax system is designed with a purpose-built muffler shape and optimized piping diameter specific to the vehicle application, ensuring low-end torque is preserved while high-end horsepower gains are maximized. This balanced approach makes the Legamax an ideal upgrade for drivers seeking both daily drivability and spirited performance.

Key Features:

  • Engineered to reduce exhaust backpressure for improved flow and efficiency
  • Application-specific muffler design and shape for optimal performance tuning
  • Optimized piping diameter maintains low-end torque while increasing peak horsepower
  • Constructed from polished SUS304 stainless steel piping for long-lasting durability and corrosion resistance
  • Broader powerband delivery for a more responsive driving experience
  • Designed and manufactured by HKS, a globally recognized leader in performance aftermarket parts

Built to HKS's exacting quality standards, the Legamax exhaust system combines premium materials with precision engineering for a performance exhaust upgrade that delivers both power and reliability.

They have the best prices and fast shipping too.

Great price and fast shipping!

Received Monroe MA770 air shock, fit just wonderful and the installation was easy.

Best price I could find! Great customer service kept me informed through the whole order process to insure acuracy since it was being sent directly from the manufacture. Recieved my order in good time, right parts and no damage. Overall very satisfied and will be doing business again in the future.

Very competitive low prices and great product selection. Will definitely look to this vendor when purchasing automotive parts in the future.

Great prices and FAST shipping!! Definitely will buy products here again!

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
