ITEM SKU: CBE-NS13-S-BT-BT+HDS+DP

Stainless Catback Muffler Exhaust System

Upgrading vehicle’s exhaust system is a great way to build horsepower, free up trapped torque, and improve upon restrictive factory systems. The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle. The net result is lower auto exhaust backpressure, more horsepower, more torque, and a much better sound.



Specifics and Benefits:

  • Made of High Quality T-304 Stainless Steel with Computerized Mandrel-Bends for Strength and Durability
  • i.e. Maximizing Smoothest High Exhaust Air Flow Rate
  • High Performance JDM Racing Design
  • Dyno Proven to Instantly Increases 10 -20 Horsepower/ Low End Torque
  • TIG Welded CNC Machine Flange for Resistance against Pressure and Corrosion
  • Aggressive Deep Sound while Ensures Smooth Exhaust Gas Flow
  • Increase Engine Output and Efficiency
  • Inlet and Front Piping Diameter: 3.00"
  • Outlet and Rear Piping Diameter: 4.00" (Muffler Exhaust Tip)


    High Performance Stainless Steel Header Exhaust

    Getting more air into your engine and more exhaust out is the key to a performance motor. That's where exhaust headers is significant as the first revenue of an exhaust system. Exhaust performance headers manipulate the air flow with the performance-robbing exhaust manifold that came with your car. Headers provide each cylinder with its own mini exhaust pipe, which means exhaust headers prevent interference among cylinders; thus, the backpressure that occurs in common exhaust manifolds. When cylinders don't have to fight with each other to expel their exhaust, they can put more power through the wheels, pushing the vehicle. Combining with a high performance cold air intake, and a cat-back exhaust system, a header system removes all restrictions of your engine, then, it is able to perform at its full potential


    Specifics and Benefits:

  • Made of High Quality T304 Stainless Steel Material
  • Inlet/ Outlet: 1.75"/ 2.50"
  • O2 Sensor Insertion and Metal Gasket Included
  • TIG Welded CNC Machine Flange
  • Increase High Flow Air, Instantly Gain 10 -15 Hp. / Tq.


    Lightweight Stainless Steel Down Pipe

    The most restrictive part of any exhaust system is the catalytic converter. The stock catalytic converter is meant to filter the flow of exhaust gases to reduce the amount of harmful gases into the atmosphere. Because of this, lots of potential performance is restrained. Down Pipes eliminate the stock catalytic converter and reduce exhaust backpressure. By maximizing exhaust flow, this downpipe allows the turbo to spool up and build boost quicker. The result brings out the vehicle’s performance potential by giving it a free high flowing exhaust system.


    Specifics and Benefits:

  • Made of High Quality T-304 Stainless Steel with Computerized Mandrel-Bends
  • i.e. Maximizing Smoothest Exhaust Airflow
  • High Performance JDM Racing Design
  • Inlet/ Outlet Sizes: 2.50”/ 2.50”
