Alpha Performance Downpipes for Porsche Macan S / GTS / Turbo 2015-2018
- Bolts to OEM location with no cutting, drilling, or 02 sensor wire extensions.
- High flow Gesi catalytic converter increases flow without compromising emissions.
- Alpha Macan Downpipes can be installed without removing manifolds.
- Laser Cut Heat shields safely keep heat from unibody.
- Organic castings maximize space and reduce bends that hinder exhaust gas flow.
The Porsche Macan’s two factory downpipes are extremely restrictive. AMS designed the Alpha Performance Porsche Macan Turbo downpipes to expel the large amount of air the Alpha filters were bringing in. They utilized the Solidworks Software program to design less restrictive transitions for the hot exhaust gasses. The creation of smoother organic transitions allows exhaust gases to flow more efficiently which lets your turbos spool quicker, delivering more power, faster. The Alpha Downpipes’ over 76mm diameter is 44% more area than the stock 63.5mm stock downpipes. With the end user in mind AMS Engineers designed the downpipes to bolt to OEM location with no cutting, drilling, or 02 sensor wire extensions. The Alpha Downpipes also were designed with heat management in mind. The Alpha Downpipes also feature laser cut heat shielding and a high flow Gesi catalytic converter which increases flow without compromising emissions or producing a check engine light. The Alpha Performance Downpipes give you piece of mind that any critical components in the engine bay will be protected by our custom laser cut heat shielding.
