i just got my agency power catback exhaust last week and i love it.. but it has alot of rasping. i have trd intake, strup header, with my agency power exhaust. so im asking where can i buy a magnaflow resonator for a cheaper price then from the main website? and also what size should i get, i heard 30 inch with a 6 inch piping would take the rasping out. i did my search but i had not luck at all.. thanks in advance!!

 

6 inch piping?????

 

.......

just get a 30" resonator and have a shop weld it in..
