Introduction

It's certainly no secret that the 981 GT4 & Spyder are regarded as one of the greatest sounding modern Porsche's from the factory in recent times. However, there's still more to be had!

Adding to the soulful scream of the 981 GT4 & Spyder, reducing weight and uncorking the 3.8 Flat Six with our Inconel Race Manifolds certainly is a great place to start.

Direct Replacement / Modular Fitment

The JCR Inconel Race Manifolds are a full direct replacement product for the OEM 981 GT4 and Spyder manifold assembly. No fabrication required and no additional parts. Simply remove the factory exhaust manifolds and replace with the JCR Inconel Race Manifolds

Light Weight

Due to the 100% Inconel construction the JCR Inconel Race Manifolds removes an impressive amount of weight from the factory exhaust set up. This truly is a win win modification.

Power Increase

Every component of the JCR Exhaust line is guaranteed to improve HP & TQ with varying results dependant on the combination of parts.

Deleting the highly restrictive factory cats along with optimising the primaries and collector design not only brings a hard edged race car sound but also drastically improves flow resulting in increased HP & TQ.
