how about having regular clamps chromed? I think you'll find that removing the spiral guts won`t make much to any diff, if your exhaust is big enough. I had 3" on my 92, 406 sbc, GMC, didn`t hurt it at all, neither did the 14" k-n air filter. I have full, 31/2" dumped exhaust on the fish , w/ a full header wrap all the way. (just because I had it laying around)
