You should look into BMW's Performance Exhaust. It really sounds good, exspecially once a few thousand miles have been put on it. It pops and crackles and sounds mean.
Does it compare to other brands like berk, AR disign, Afe. I will spend the money and would rather go with PE if it gives the same results.
