My GN has a custom 3"dual exhaust that a previous owner had made. It's actually pretty nice except for the flowmaster mufflers which I hear don't work well on turbo cars. My 67 Camaro needs a new exhaust as it currently has longtubes with glasspacks circa 1970 dumped at the axle. It's obnoxious and looks like hell. So I'm thinking about pulling the 3" flowmasters off the GN and putting them on the Camaro with an x-pipe.
My question is, who has switched from flowmasters to something else with proven gains either on a dyno or track. I'm thinking about putting either dynomax ultra flow welded , magnaflows, or pypes race pro's on the GN in place in the flowmasters. Or is there another reasonably priced muffler to consider? I want something that will make some noise when I want it to but I don't want a muffler that will drone on the highway.
