Resonator Location

[Bad Fishy]

Hi Goody, first off...nice ride! I’ve seen your car in several blog posts!



I just had a new exhaust installed, along with a significant top end motor upgrade, but my new system has some drone. I’m using Dynomax Ultra Flo’s, 2 1/2”. Previously I was using the same but 2 1/4”. Also added an X pipe. I’ve looked at the sound apps and calculations to determine the proper length of pipe.

I see you have J-pipes, but what are those attachments at the end? Exhaust cut outs? Would like to know more about that as I am also considering something similar - don’t have room for cut-outs AND J-pipes in separate locations. If they are cut-outs, they still seal tight enough to produce the resonance-killing backwave? if they are not cut-outs, what are they? I appreciate any help.
