2.5 in borla vs 3in mac

[SeriousCobra]

is there going to be a huge power difference here?

i ask because the borla seems to be a very popular choice and its only a 2.5 and i see many people run it.

thanks

Not gonna be a difference in power. Where you would pick up with the 3" piping you'll lose in the backpressure of the chambered mufflers.
