Alfa 4C High Flow Cat

2,125.00 2,200.00

The Capristo 100cel high-flow cat is specifically made to offer better flow and lower exhaust temps on the Alfa 4C coupe and spider.

The lower exhaust gas temps will allow the turbo to boost better without intervention by the 4C ECU, especially in hard use situations like on a racetrack. 

Proprietary castings from Capristo have been developed for the smoothest flow possible of exhaust gases, exceeding the capability of other typical welded tubing designs.

Then Capristo mates the cast ends to an HJS-Motorsport center cat material, HJS is the regarded as the world leader in Motorsport catalyst production and development, with many race programs using their cats. FIA approved and used in BTCC, WTCC, WRC, WEC and LeMans cars.

When combined with our ECU tuning expect around a 10hp increase from the high flow cat alone.

Numbers on a stock 4C ECU slightly less, but lower exhaust gas temps and higher flow will benefit the engine and turbo.
