[QUOTE="Catmonkey, post: 16234623, member: 124025"] I used Vibrant's 18" bottle resonators just off the mid-pipe. My mid-pipe is 3", so I used 3" i.d. for the resonators, necking down to 2 3/4 right after the resonator. Before that, I couldn't stand my Borla Tourings with long tubes and no cats. Anything above 1/4 throttle was way too loud, so I ran the OEM mufflers for a good while. My car is a 2012, so I don't have the quad outlets, which may be worse. With the resonators, I was able to put the Borla's back on. I haven't tried the OEM muffler with the resonators, but I'm thinking it wouldn't be that bad. But the resonators with the Borlas was at least as quiet, if not quieter, than the OEM mufflers. Now my hearing is really bad, but I got hearing aids a few months ago about the time I got the car back on the road, so I'm thinking the resonators did a pretty effective job. Nothing will be as quiet as the complete stock exhaust and cats if you're really noise sensitive. [/QUOTE]
