Milltek SSXAU727 Catless Front Section for Audi 2.5 TFSI DAZA

Unlock the iconic five-cylinder sound and serious flow with this big-bore, catalyst-removal front section from Milltek. Designed for the Audi RS3 8V facelift pre-GPF and TT RS 8S, this UK-built turbo down pipe uses 76.2 mm tubing to reduce back pressure, sharpen turbo spool and let the 2.5 TFSI breathe. It bolts straight up to the factory rear section or a Milltek rear system for an easy, high-impact upgrade.
