A perfect match to OEM or Exoticspeed cat-back exhaust systems and OEM Muffler. All Exoticspeed headers are made from stainless steel mandrel bent pipes. Great care was taken during the design to enhance the performance of your normally-aspirated or Supercharged vehicle, by fine-tuning the placement, size and angle of each collector to even out the exhaust pulses. Combined with large primary runners make Exoticspeed Headers a solid choice for your vehicle.
