Ultima Sports Exhaust - Porsche 991

"Coup de Cœur" Sports Muffler (Without Valves) for Porsche 991

On the Porsche 991, the majority of the sound is found in the rear center muffler. This is why our valveless Sport version is so convincing and is our "favorite" as an alternative to the valved version.

Sound & Benefits

• Perfect balance: Offers a significant and sporty sound during rev changes, while becoming discreet and comfortable at cruising speed.

• Easy Adjustment: The muffler body is adjustable, allowing for a perfect fit during installation.

• Alternative available: A Sport version with valves (Ref: SCA 991 3 2 VI or VT) is also available for those looking for greater sound amplitude.

Installation & Features

• "Plug & Play" assembly: The muffler respects all the original interfaces (inlets, outlets, dimensions) and is mounted in place of the old part, without any modification.

• Average installation time: Approximately 3 hours , including removal of the original. Removal of the rear bumper is necessary.

• Optimization tip: Since removing the bumper gives access to the air filters, we recommend taking the opportunity to replace them with sports versions.

• Required Equipment: A lift is preferred for greater comfort, but is not essential. Tightening the nuts should be done gradually.

Kit Contents

To ensure installation in the best conditions, a complete mounting kit is included in the price. It includes:

• The joints

• Stainless steel screws

• All-stainless steel lock nuts

• The two fixing straps

• Copper grease
