right now i have a 5zigen canonball rear section welded to the the stock piping. how would it sound with a project silvia resonated test pipe. would it sound ricy or would it still have a deep tone just louder?

 

deep tone louder... but i can make you one for $50... no resonator just a straight up test pipe...

 

Yup, that is how mine sounds with the project silvia testpipe and URAS exhaust.

 

i've still got the ka not an sr will this make a difference

 

ehh i dont want to bring up the backpressure theory.. but because i knew i was going with my SR soon enough i went ahead and bought apexi n1 and made a 3 inch test pipe ON the KA just for shits and giggles and idk barely any power loss... it will be fairly loud though so up to you...
