My current exhaust is a tad on the loud side with some drone with the two can GHL muffler. I have cat delete pipes on my 02 S and was thinking about adding some resonators. I'm thinking one per side in the cat delete pipes where they feed into the u-bends. I think there is easily enough room for a 3.5 " case diameter resonator with 12 " overall length and maybe a little longer. Off the top of my head I don't remember the ID/OD of the delete pipes and I know I will have to transition from the resonator size ( 2.250 " ? ) to the u-bends ( 2 " ? ) but any competent muffler shop can do that. So are any of you running cat delete pipes with resonators ? What resonators did you use ? Any pics of your setup ? I'm thinking of using something like these. My goal is to just tone down the sound a little ( 10 - 15 % ) and cut down on the drone.
