Ultima sport exhaust – Porsche 911 (991)

On the 991, most of the sound lives in the rear centre muffler – which is why our valveless sport version is so convincing: it is our personal favourite, as an alternative to the valve version. A meaningful, sporty sound through rev changes, discreet and comfortable at cruising speed. The muffler body is adjustable, for a perfect fit during installation.

Fitting

• Strictly original interfaces (inlets, outlets, dimensions): direct replacement, no modification
• Average fitting time: around 6 hours including removal. The rear bumper must come off – it gives access to the air filters: a good opportunity to switch them to sport versions
• A lift is preferable but not essential; tighten the nuts progressively
