Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.

DME/ECU upgrades are available for all 993 Carrera models, but you must specify which style of DME/ECU your vehicle requires. Early model 993's (1994-1995) typically use a DME software chip, while the later cars (1996-1998) use an ECU software tune. Cars equipped with the "drive-block" feature (any model years) use an OTP-style ECU. You can verify that your car requires an OTP by inspecting the stickers on your factory ECU. If the number on the Porsche sticker is 99361866600, 99361866601, 99361866602, or 99361866603, then you will need to select the OTP ECU tuning option.
DISCLAIMER: The original factory ball-joint clamps must be re-used when installing Fabspeed exhaust products on all 993 Carrera vehicles.
You must specify what style of header flange your vehicle uses: either Gillet (1996-1998) or Bischoff (1994-1996.5). Please refer to the photo below if you are unsure!
