Oh chill out im over this its kiddish
we can talk and have our opinions.......
Was saying you should get the right size to fit the catback like 3" to 2.5 ya know ...thats if you dont have plans to change the catbackk err.
idc what anyone says when you open up something it will give more sounds just like if you had a horn kinda closed up then you open it more and you will get more sound.
yeah the dp takes most of the credit for the iimproved sound. But opening up the front manifold to equal the size of the rear is gonna make the sound equal out a little better.
