Looking at getting an x-force cat back exhaust.deciding between a twin 2.5" cat back or single 3.5" cat back.hoping someone can help me with a few questions:1. Does anyone know which exhaust is louder; twin 2.5" cat back or single 3.5" cat back.2. Will a re-tune be required.3. Which exhaust will make more power? 1 Link to comment https://www.fordxr6turbo.com/forum/topic/84210-fg-twin-25-vs-single-35/ Share on other sites More sharing options...

Supported 320rwkw Went to 3.5" sounds nice as is and is good for my 385rwkw.Catback systems are fine but if you touch the cat you will need a tune.3.5" is the better one to go for if chasing power.... 2 Link to comment https://www.fordxr6turbo.com/forum/topic/84210-fg-twin-25-vs-single-35/#findComment-1369052 Share on other sites More sharing options...

Also for some reason turbo cars respond better with a single system. Veloscity I suspect.
