PERON 3.5" Sports Cat Downpipe - Ford Fiesta ST 1.6T

PERON are proud to introduce our new and improved Super Stock 3.5'' Turbo Sports Cat Downpipe now featuring an increased loading for improved emissions efficiency on a cold engine start.

Manufactured in-house from 100% T304 stainless steel including flanges, flexible section and lambda bosses. This unique downpipe utilises an 89mm elbow mated to 127mm Motorsport catalyst which then transitions to 76mm pipe work to a CNC 76mm 2 bolt flange arrangement.

If you are looking to maximise the power from your stock location factory or hybrid turbo Fiesta ST look no further than this beautifully robotic TIG welded downpipe. 

To maximise the performance of this component a PERON STG2 calibration is required for use with the stock turbocharger; this will also remove any engine management lights.

Optional Extras

The PERON Cat-Back Adapter Kit gives you everything you need to connect your performance 3" de-cat or sports cat downpipe onto either your stock cat-back or a 2.5" performance cat back exhaust system.
