So I'm doing research on exhausts (I need to alter/change mine) and came across this. Might prove worthwhile to those thinking about changing their own.
Consequently I'm looking at changing my exhaust by removing the y-pipe (my exhaust is not stock) and inserting a single inlet dual outlet chambered muffler to two large offset inlet outlet circular mufflers in the stock location. This should prove interesting

Although those deal with piston engined cars, their information is still nice to have.
Furthermore anyone who has experience with exhausts please feel free to post.
