I have an early ERA 427 SC with a 428 FE big block and sidepipes.

My ears (and other internal organs) are telling me it's time to replace the sidepipes with quieter ones. Fortunately, the police have yet to "advise me" of the need.

My problem? Removing the sidepipes from the "slip fittings" on the individual cylinder pipes. (Why they call them "slip" fittings escapes me...)

Yep.... I have the retaining bolts removed from the slip joints. I've tried the loosen-the-sidepipes-and-give-them-some-hard-tugs approach. No luck. I've also sprayed WD40 into the slip joints, let the FE idle (until I was getting smoke from the WD40, and tied the hard tugs again--this time, with the help of a rubber mallet. Still no luck.

Anyone have a good Plan B, or C or D?

Thanks
