88 Lancer ES? Need Muffler

[88lanceres]

Hello,

Later on when I get the transmission finally put in and stuff, I wanna replace the stock turbo muffler thats single in dual out. I can hear the turbo whistle in exhaust right now hehe, Would it hurt too put a Flowmaster 40series on this car? Would it hurt performance vs. Stock? I want it too sound good, Has no converter right now just OEM Muffler. Ive heard Dynomax Ultraflow are good performance mufflers but I think they sound kinda bad. Some suggestions please, Im looking for good sound and same or better performance over stock.

I have a dynomax super turbo in 2.5". Pretty quiet but a little rumbly at idle. I think flowmasters are gay, but that's probably cause there are so many **** stock mustangs V6s around here that have em.
