Product description
Made specifically for BMW N55 Engine
Project Gamma downpipes for the N55 engines feature a 4” construction along with a stainless steel v-band to pipe transition that is machined with CNC to precision. Our downpipes are the best bang for your buck mod available for your N55 engine with gains from 50 Horsepower and 60 Torque when tuned. Project Gamma keeps the full pipe diameter right up to the turbo instead of necking it down, which helps flow. They're hand-built from 304 stainless steel, which resists rust.
The pipes in the photos have the optional ceramic coating. Add the ceramic coating option to cut heat in the engine bay; without it, the downpipes come polished.
Features:
- More power through the rev range
- Sharper turbo and throttle response
- Less turbo lag
- A louder, more exotic exhaust note
- Accurate fit that keeps the factory heat shielding
Note: This product requires installation by a technician and will need tune recalibration to avoid cel light.

PRE-PURCHASE & SHIPPING FAQ
How does the order-in process work?
We verify live supplier inventory and issue a comprehensive written quote covering the part, current AUD pricing, GST, and tailored freight to your address (or free Stepney collection). Once you review and approve the quote and vehicle fitment is confirmed, your order is secured directly with our manufacturer allocation.
What are the estimated delivery times?
Typical delivery is 1 to 2 weeks for air freight sourced directly from verified European and international manufacturers. Active consignment tracking is maintained throughout transit until parts arrive at our Stepney workshop for collection, workshop installation, or dispatch to your door.
Can I pick up or have parts installed locally?
Yes. Free local collection is available from our Stepney workshop facility in Adelaide. We also offer professional in-house fitting, alignment, and calibration by European platform technicians. Simply select "Supply and fit at Stepney" when submitting your enquiry.
What happens if fitment is uncertain?
Our workshop technicians cross-reference manufacturer technical schematics, platform codes (such as S58, B58, S63TU), and your vehicle registration or VIN before placing the order. If there are model-year variations, aftermarket modifications, or clearance concerns, our team confirms compatibility with you and the supplier prior to commitment.
