Exahaust pipes

[Jvacustoms]

Now I was looking at a post about a chinese 250 earilier and taking a look at it, it had dual pipes I was wondering if possibly making a dual pipe setup from 1.25 " pipes and making an exhaust cross over before the muffler would improve performance...

Just a thought.

Found some all chrome straoght pipes made for a rv generator and insert internal baffles at the ends making it look like a straight pipe but with a quality sound.

Want to know other opinions on this idea before giving it a shot
