I've been looking at install pics and listening to sound clips and so far this looks/sounds like a nice setup. At 70mm, if you are using a 3" cat, I don't see the exhaust being the flow restriction. However that is if the mufflers are not baffled or their piping isn't two narrow. I can't find a picture showing it or dimensions on the mufflers and tubing. Anyone have any information on this? I saw the video of someone with this exhaust on a greddy kit putting down 327 whp and it sounded fantastic.
