Are the reasonaters used for drone reduction or sound reduction?

Agreed....with SS X pipe, and E race....I have little to NO drone

with the X pipe (no resonator), I did notice loss of back pressure and some free flow air (faint popping noise)

The main function of the x pipe is to equalize exhaust pressures, by doing this it does also effect the noise, but without resenators you will have a higher raspyness to the exhaust note.

I ask because my local quality muffler shop will build one on the car for $225.....not SS but I don't really care....if it performs the same function as a $500 one......they why not....
