I am back in the modding stage once again. I was looking into different types of test pipes and i always see either resonated or non resonated for sale on the forums. What is the difference? Is there such thing as "non rasp" test pipes? I had a set last year and i got too annoyd of the rasp sound so i sold them but everything else i loved about them so now i am considering geting them again

 

resonated test pipes remove a lot of the rasp with nearly the same performance benefit of the non-resonated.
