That may be my next purchase. It looks very similar to the resonator that came on my GMPP catback. My sons new GMPP catback sounds much quieter (nicer) than my GMPP w/o the resonator. I could either try another resonator, get a new GMPP, or a new stock catback. Will try the resonator and if that doesn't make enough of a difference, it's stock again.
although not totally accurate can you put the recording device in the truck so we might hear WOT or hiway sound? The V6 sound is just embarrassing and being able to have something that flows well, but is quiet would definitely be a plus.
