Stainless steel cat replacement pipe. Replaces the large catalyst to reduce exhaust backpressure. Results in faster turbo spool up. Not recommended to use with the downpipe on 16v JTD engines equipped with the OEM turbo because of boost creep. Fits every 1.9 JTD version of the Alfa 147, 156 and GT with exception of the 156 Crosswagon 4×4.
Fits Alfa 147,156 and GT 1.9 JTD 8v/16v
