I know there are others out there that take care of the sidepipe itself but no one offers an alternative to the collector issues from header to side pipe. If you look at those collectors , a 2 inch primary times 4 is squeezed down to really a 1 inch through that collector.

I could be wrong, but that looks like the Factory Five J-pipe (
1987-1995 J-Pipe Kit - Factory Five Parts Catalog). If so, a better solution would seem to be their headers for the 302 (
302 Headers - Factory Five Parts Catalog) - full size primaries all the way to the side pipes.
