Does anybody have any ideas as to the performance gains on the Mazdaspeed exhaust vs. the Racing Beat catback?

I have the potential opportunity to get the Mazdaspeed for around $160 in the near future.

Was planning on getting the racing beat but that would be a ways off. I have heard the way the mazdaspeed sounds and I like it, just curious as to what the performance difference is between it and the Racing Beat and if the cost difference would be worth it giving the opportunity I have with the Mazdaspeed.

Thanks for opinions!

 

I can't speak for the Racing Beat, but with my Injen installed, and te Mazdaspeed exhaust, my "butt dyno" noticed a bit of a boost... Not much, probably only like 3-5HP, but I did notice something...

 

the racing beat is a cat-back and the mazda speed is only an axle back. the racing beat should produce more gain if any in horsepower between the two. but both is more free flowing than stock. hope that helps
