PPE Headers have a significant increase in flow compared for the 2ZZ-GE swapped MR2 Spyder. Completely TIG welded construction with thick 16 gauge tubing for long lasting power gains and optional parallel merge collector.

• 1 5/8″ stepped to 1 3/4″ runners and a 2.5″ outlet.
  
• Construction is stainless steel for a long service life.
• Standard collector provides good airflow and modest gains at an affordable price.
• Optional Parallel Merge collector option, made-to-order.
• Installation hardware and outlet gasket included. You may wish to replace your head to manifold gasket (sold separately)
• USA Made

This kit includes:

• PPE Header x 1
• Header Bolts w Spring & Washers x 2
• Outlet Gasket x 1

Q: What are the benefits of upgrading to a parallel merge collector?

A: A parallel merge collector makes the transition from primary tube to collector as smooth as possible. This reduction in turbulence helps maintain velocity through the collector, thus increasing the scavenging power of the header system. Gains may be minimal, without supporting modifications to the cylinder head and intake systems (port, polish, valve-job).

• Bolts up to PPE’s 2ZZ-GE high-flow cat or 2ZZ test pipe (required). Does not bolt to MR2 1ZZ stock midpipe.
  
• Right side, Upstream O2 sensor wiring must be lengthened to reach the collector area. Left side, Upstream O2 sensor, due to the 2ZZ-GE ECUs requiring only one upstream O2 sensor.
• This product is intended for off road use only.
