Does anyone have before and after dyno chart w/ a long tube upgrade? I am trying to see exactly what can be expected from an upgrade to long tubes. As seen in my signature, I have only basic bolt-ons and don't plan to do any "major" mods (heads, cams, blower, etc).
If no dyno charts, then how about before/after 1/4 mile ETs w/ no other mods?
