do basically all straight through design exhausts sound and perform the same, as long as it is the same diameter? also i cant find anyone with vibrant parts, does anyone know where i can get these? thanks for any help.

 

they all perform the same but will sound different based on the style of muffler and resonator

 

straight through designs all have similar sounds. But its distinct between a greddy evo, and apexi ws, catch my drift.

Vibrant never heard of them.
