If you do it, please do it properly, you can lose hp and performance due to the lack of the backpressure that is created with the single exhaust.
One thing you might want to do is check out performance muffler shops... they can give you a better idea of what you can and can't do.
Also look into the muffler on a Vette, they are small enoguh for you to run duals.
Before I trade off the 01 for the ES we had welded it in place directly ahead of the spare tire and that worked well....
which ever way your gonna go there is gonna be alot of custom piping that is gonna be needed.
Right now is the planning stages of running duals on the ES coming out the sides so if you have questions contact me
