yes 12" are louder then 18" but you can also go no resonators on the exhaust. Test pipes comes in resonated or non-resonated.

i have the MXP Resonated Test Pipes with MXP CBE... i love my setup! you could search youtube for my dyno video if you're really curious on the sound.

it's raspy, but kinda in a good way... once cruising in 6th gea,r the in-cabin sound is surprisingly quiet!
