i have a flowmaster 40 series with delta flow on my 4.2 v6. right now i have it exiting behind the rear wheel. I was thinking about either having it ran straight back or just dumping it right out of the muffler. I want it to be the best path for it and the loudest. does anyone know which one would be better or which one would be louder? thanks

 

Well for a v6 we did we got the shortist glasspack we could find and hammered a pipe through it and put it on. damn thing is so loud it hurts your ears(oh yeah we also removed the cats)

I hope this helps!
