exhaust dilemna

[DW5.0L]

I am in the process of assembling my car after a rebuild project. Currently it has 2 1/4 2 chamber flowmasters on it. I have a set of BBK shorties on the rebuilt block and their X pipe.

Whats the disadvantage to running the car with a 2.5" X pipe into 2.25" catback? I have already spent more than initally planned, but I guess a few hundred more on a bigger catback won't hurt. Thinking about the Dynomax Race Magnum kit from Brothersperformance.

Any opinions on the different pipe diameter and performance?

Dont worry about running the 2.5 into a 2.25. Whatever loss there may be can be gained back plus some if you spent that money somewhere else.

With the changes you've made thus far, the 2.25" cat back isn't hurting you. Don't worry about it --

run it for a while.......if it gets to bother you to much then buy 2.5 flow tubes and dump your mufflers.........(put dumps out of mufflers).

Ok, thanks for the input. I guess I'll just save my $ for now and see how it goes when I start it up and drive it around for the break-in period.
