Exhaust question...

[Goodman]

Hi! to all, i got an Alero 2001 4doors V6 & wanted to get a "Dual" exhaust with two mufflers (Dynomax Turbo) more than single Camaro type muffler...

I saw some Youtube video & the "dual" exhaust with two mufflers sound much better IMO as i am looking for a muscle car type of sound more than anything else

Here are two Youtube Video the first one is more the sound i wanted at idle anyway...
Dual exhaust/mufflers:

Single muffler with dual out:

Hear the difference?

Unless some one here can tell me what kind/type of a muffler with single in & dual out (Camaro type muffler) can do the same sound as two mufflers with dual exhaust i am all for it as it would be a cheaper buy...

One thing i am confused about is the Y-pipes does it start at the Cat (Cat back?) & then double exhaust up to the mufflers or is the Y-pipes start in the back right before the dual mufflers , like the dual exhaust of GA GT?

Thx!
