Product Details

Backed by an industry leading lifetime warranty, our Competition Headers for the Porsche 981 are an excellent performance upgrade from the restrictive, heavy and muffling stock manifolds. By replacing your stock manifolds with our bolt-on upgrade you will eliminate the restrictive, power robbing and weak factory catalytic converters with proven design elements including port matched flanges, smooth radius large diameter primary tubing and collectors that optimize the exhaust flow as efficiently as possible. By creating a unique application for the 981 platform, we’ve focused on sizing the runners and collectors correctly to extract maximum from the 3.4L engine while producing great gains from the 2.7L as well.

You’ll notice the weight savings of 11 lbs, decreased operating temperatures and improved engine response, all while separating your car from the crowd with the increase in tone from Soul Performance Products Competition Headers.


  • Direct bolt on installation – instructions included
  • Constructed from 14-16ga T304L stainless steel tubing
  • All Soul Performance Products are backed by their Limited Lifetime Warranty for both street and track use
