I have seen the formula for figuring the desired J pipe length but my question is if this formula works for a true dual system? I don’t want to build the wrong size J pipe due to having a true dual system
Thanks

I know this is an old thread but I had a question I didn't see addressed. Is longer better for this application? In other words if I make a 30" pipe does it address all drone from 1,500-2500 (as an example) or is it targeted at only a specific RPM. Like 30" would be suited best for 1,500 plus or minus a little but would not work the best for 2,500.
