Universal 2.5 x 2.75" 45 Degree Silicone Coupler (FR-UNI-SIL-2.5/2.75/45)

The Full-Race 2.5" x 2.75" 45 Degree Silicone Transition Coupler is a heavy-duty, angled component designed for a smooth diameter transition while navigating tight engine bay constraints. This coupler steps from 2.5 inches up to 2.75 inches with a 45-degree bend, which is often used to connect larger throttle bodies to 2.5-inch charge piping. Constructed from durable 4-ply silicone with a robust 0.110-inch wall thickness, this coupler is engineered for extreme durability and boost levels, resisting tearing due to engine movement and heat expansion.

Features

• Features a 45-degree bend for angled transitions with a high-flowing, tight radius.
• Designed for a smooth diameter transition from 2.5 inches to 2.75 inches.
• Constructed from heavy-duty 4-ply silicone.
• Features a thick wall of 0.110 inches for maximum durability and strength against high boost.

Notes

• Often used to connect a 68mm or 70mm throttle body to a 2.5" charge pipe.
• Requires appropriate clamps (T-Bolt clamps recommended, sold separately) for secure installation on both ends.

Compatibility Notes

• Suitable for custom charge pipe fabrication and modifications involving a mild pipe diameter transition with an angle.
