Stepping an exhaust up in size usually happens where two sections of different pipe meet, and forcing one into the other never seals. A concentric reducer makes the change in a short section and keeps both pipes on the same centerline.

Vibrant Performance 2686 Concentric Exhaust Reducer Features:

• Transitions between 2 in. and 2.5 in. tubing.
• 2 in. overall length keeps the transition compact.
• Concentric shape holds both pipes on the same centerline.
• Formed from 304 stainless steel.
• Weld-in design for custom exhaust work.
