3 inch or 2.5 inch


I have some 3 inch headers, well the collector is 3 inches, and they come with a reducer that takes it down to 2.5 inches Should I go that route, or just stay with the 3 inches. I had ordered some cats that were 3 inch, but I can probably change my order. 5.0 stock

Thanks

Stick with 2.5", it'll be better for your power level.

Depends on your future plans...

If you are going to stay N/A 2.5 is fine...

If you are going to boost it I recommend a 3inch...
