GAP, singular.
what are you not understanding??? i chose to do a side exit because i dropped my cat back to go to the track but found out my resonator i had on the cat back was bad(internal were rattling)so i started cutting out the resonator to replace it with a straight pipe but said screw it im gonna make my own side exit. so i did. its lighter than a full cat back, it flows a lot better and i like it. plus i ordered a round magnaflow muffler to quiet it down some. muffler is going on after the headers same area as reasonator.shoulda put it through the side skirt.
and im still not understanding why.

Probably because you either don't have a FB or we aren't mutual friends. I'll link it later then.
I'll extend an "E" for effort, but Holy God do these engines sound like ass. Quieter is better.
