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

Thx you all for good informations

12" or 18" resonators is it a lot different in sound volume?
I like the one that show on the clip very much. Which one that he use?

12" is a good bit louder than the 18". 18" has a deeper tone, though.

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!
