For the Mazda 3 I have heard that Magnaflow and Greddy are making cat backs. Any thoughts as to which one is better?

 

Go Greddy.

 

the CorkSport power series sounds awesome very low not honda ish

 

the sound of the 3 at rev it up was sweeet.... though i am not sure if it was cat back or just a muffler.... i thought i remember it as a borla...??.... could probably look it up and find out but it had a real nice deeper note to it

 

that sux.

 

does this system throw any cel up
