I want to get my restrictive stock mufflers off my car but dont want to be annoyed my loud less restrictive mufflers so I'm asking the GP world. Whats the quietest high flow muffler I can get? 07 grand prix gt s/c daily driven. I like a little rumble but don't want my ears to bleed. is there a muffler wheres its somewhat quiet under normal driving but loud under heavy driving?

Your stock mufflers aren't restrictive at all. So if restriction is your problem, I wouldn't change a thing.

If you want a better sound, I suggest a set of borla mufflers. They are expensive, bit will give you alittle more tone. Anything else is going to be very loud.

The manifolds are more restrictive than the mufflers, start there if thats what youre worried about.
 
I have assc headers on the way. 3.6 pulley installed, 180 stat, overkill pcm, k&n cai, res delete with straight pipe and autolite 104s
 


Go on youtube, I doubt it really does it justice but the magnaflows sound good on there. My friends monte also has them and it sounds pretty good.
 
remove res, put in glasspack. leave mufflers stock. get headers. thats the best sounding you will get out of these cars, sad to say.
 
Oh yay another exhaust thread where everyone tells the OP to just leave the stock cat back alone but won't listen............
Not like there aren't already a million of them.
