Any recommendations for replacing the factory muffler on my 97 SL sohc 5spd. Strickly interested in improving mileage. Do I just replace the muffler or the resonator as well? Obviously don't want the car to be obnoxiously loud...

Dynomax Super Turbo is probably the quietest performance muffler.
I'd consider replacing the tubing bends with mandrel bends of the same size.
The resonator doesn't need to be removed, because it is basically the same as a glasspack.
