The Akrapovič Slip-On Race Line (Titanium) is a full titanium track exhaust system developed specifically for the Porsche 911 GT3, GT3 Touring, GT3 RS, S and T (992). Every system we sell includes the mandatory Slip-On Race Line Adapter Set in the price — the part you need if you're keeping your factory headers — so what you see here is exactly what turns up ready to fit.

Why This Listing Includes the Adapter Set

If you're retaining the stock headers (as most GT3 owners are), Akrapovič requires the separate Slip-On Race Line Adapter Set (P-CP034) to complete the installation — it's not optional. Many retailers list the muffler on its own at a lower headline price and leave you to discover the adapter is a separate purchase at checkout. At AUTOID we combine both into a single product and a single price. If you're planning to run the full Evolution Header Set instead of the stock headers, get in touch — the adapter isn't needed in that case and we can price the system without it.

Titanium Construction, Race-Bred Engineering

Developed solely for the 911 GT3 family, this high-grade titanium system is sandblasted and coated for durability, with a completely new twin-tailpipe design — the inner sleeve carries six imprints to match the flat-six engine, finished with an engraved Akrapovič logo. The exhaust valve housings and muffler collectors are cast at Akrapovič's in-house foundry. No ECU remapping is required, and the system fits vehicles equipped with an Otto particulate filter (OPF).
