Milltek Sport SSXAU226 Secondary Cat Delete/Decat Bypass Mid-Pipes for Audi TT RS Mk2 8J (TTRS) & RS 3 8P 2.5 TFSI S tronic – Catless Centre/Center Mid-Section 63.5mm (2.5")

Turn up the five-cylinder character on your TTRS Mk2 and RS 3 8P

Looking for a harder edged soundtrack and freer breathing mid section on the 2.5 TFSI platform without changing the whole system? This high quality Milltek centre section replaces the factory secondary catalysts with straight through sections, unlocking a deeper tone, sharper response and more turbo whistle. Expect a cleaner, more aggressive note under load while retaining everyday drivability.

We have installed this upgrade for customers at MJ Modifications and the feedback is consistently positive on sound, fit and finish. If you want your 2.5 TFSI to sound the way it should, this is a proven, great value exhaust mod.

Why enthusiasts choose this secondary decat setup

• Specifically made for TTRS 8J and RS 3 8P S tronic 2.5 TFSI applications

• Transforms the mid-section into a catless straight pipe arrangement for improved flow
• Enhanced five-cylinder tone with more volume, crackle and character
• Works with the factory rear silencer or aftermarket cat-back systems
• No cutting or welding required - uses OE-style connections
• Tubing size: 63.5 mm diameter - 2.50 inch
