If you plan on adding a header down the line, I recommend going with the resonated setup vs the non resonated. As adding a header, instantly makes the car MUCH more vocal.

I recommend the non resonated setup mainly to customers that want a louder/deeper toned exhaust, but do not plan on adding a header.

If loud is what you are aiming for, I'd recommend looking into our 3" exhaust. It is by far my personal favorite in regards to tone/loudness.
