Does the Resonator restrict any airflow? How much louder would the exhaust system be without the resonator?

 

No, and quite a bit

 

it is alot louder i took mine off and just ran the car from the y-pipe. and also tried it with the y-pipe, catt, and then just a pipe all the way back. it is very loud now and doesn't have that hollow sound to it.

 

Do you like it being that loud or does it get annoying sometimes?
