What sound better on accleration mustang flowmaster true duals or the mac y pipe set up what has all around better sound.This is what i have been hearing that the flowmaster sound good on idle but the acceleration noise is not that amazing and that the macs idle sux but the accelration sound is great. Which one adds better performance? I have been stuck on this decission forever and i just cant decide i want some honest opinions i live in az so rust is not a problem. I wwant my car to sound all around good and a deep sound not ricey. thanks

 

stay far far away from y pipes
get true duals, maybe an x or h pipe set up and spend an hour or two on street fire or youtube listening to exhaust setups, to be honest ive spent hours listening to exhaust and i still havnt found one on my model year car that sounds like i want it to
trust me study this and do your homework, itll be money well spent

 

most important thing is don't go with cheap brands like pypes.. they sound bad..

 

i think youve kinda got it backwards, mac sound good at idle and blow everywhere else and flows are just quiet at idle and sound amazing everywhere else. thats my opinion. id go flows

 

I think you both have it backwards, mac's sound good all arround.
No one sounds betterthan the other, it's all your matter of opion of what sounds good to you. You are going to get a different response from everybody.

 

Stay away from the Y-pipe setup, it doesn't really make a lot of sense as it still restricts performance. Seems like a waste of money to me.

 

go true flows, u will love the sounds all around, even at redline it wont be high at all

 

duals seem useless too meeunless you go forced induction or built the engine up

 

not at all, a y pipe seems useless to me unless u wish to keep ur car completely stock

 

So should i just go with true duals 40's original?????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????
