I am looking to go with a Dynoflash and exhaust, but want to keep the stock cat. My initial thought is sticking with a 2.5" DP to match the stock cat, and then going either 2.5" or 3.0" catback (or possible Busher axle back).

The questions I have are:

1. Would there be any difference between the 2.5 or 3.0 catback?
2. If I only plan on running stock boost levels, is there any value in getting a MBC, or does the flash maintain consistent boost levels?

Thanks,

T

 

Bump.
