We wanted to design a muffler replacement that not only fixed that issue but also improved on the OEM design. Using our 25+ years of air and water-cooled experience, we took the valve open tubing to 2.75in \/ 70mm which is the optimal diameter for GT3 engines to have low restriction but maintain high velocity and high GT3 pitch for the signature GT3 CUP car sound. Then, we implemented our signature investment cast X-Pipe for optimal exhaust scavenging. The X merges the two cylinder banks without creating any restriction in exhaust flow. To maintain the factory muffler’s exhaust note and lack of drone, we mimicked Porsche’s 7 chamber design. This makes for a completely drone free muffler, even when running catless race headers!
