which is the loudest?

2 chamber flowmaster will be loud no matter were it exits. Run tail pipes and tips at the en and keep the fumes out of the car. Also a balance pipe will add torque.

i agree, i used to have 40series flowmasters and they are loud nomather how i listen to them...
yea put some tailpipes on , sure they will take alitle sound away but thats not a bigproblem compared to the risk of getting toxicated..... and flowmaster 2chambers are loud enough anyway, no problem running them at the bumper if you have a fuelcell in the trunk otherways keep the mufflers where they belong in the pockets in front of the axle, that makes the whole exhaust look alot cleaner
