Hey guys if i can jump in here to, i am looking for a testpipe and down pipe that will give me the power . and i am currently running a Greddy sp elite cat back and its not as loud as id like it to be, it has a growl when i step on it, but no nice hum or grown when just driving, what test pipe and down pipe will deliver the power and the loudness that i want, plus i just got a cobb access port aswell. what are your thoughts?

thanks guys
