Description
The Milltek Secondary Catalyst Delete Pipe removes the secondary catalyst from dual-pipe exhaust assemblies, improving gas flow and reducing flow restrictions in the exhaust system. Direct fitment to Milltek cat-back systems and compatible with OEM cat-back assemblies on applicable Audi models.
Constructed from T304L stainless steel with mandrel-bent tubing, this secondary cat bypass is engineered to work alongside existing primary catalyst systems. Hand-finished construction ensures OEM+ fitment and durability. No modification required for installation.
Fitment:
- Compatible with Milltek cat-back exhaust systems on dual-catalyst Audi models
- Works with OEM factory cat-back systems where secondary catalyst removal is desired
- Direct bolt-on fitment—no welding or cutting required
T304L stainless construction with precision mandrel bending delivers lasting durability and measurable flow improvements over secondary catalyst restrictions.
Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
