Difference between 2 chamber and 3 chamber Flowmasters

  • Sponsors (?)


:stupid: Listen to some audio clips of each and go by your sound preference!

i can't find audio on the 50 delta series other then the one on flowmasters website. I just thought that 3 chambers would slow air flow more then 2 chanmbers :shrug:
I'm not to much concern about the sound but more on the performance.

Someone locally is selling some 50 series deltas that are 2.50 ...My mustang has the originally 40s welded but they are 2.25 like the stock catback. I have a magnaflow catback (2.50) ready to install but need some 2.50 mufflers to install it with. I was just going to use the 40s I have in there but then that would defeat the purpose of having a 2.50 catback when the mufflers are only 2.25. So i want to jump on the 50 series if they won't drop my performance (which sounds like they won't)
 
no chambers sounds best. (my $.02)

go with a straight through to ensure maximum performance gains

if youre lookin for a deep sound. get a catted h pipe to pair with the straight through catback.
 
dont go with 3 chambers.. i have flowmaster force 2's.. with LT"S and offroad H pipe and its still pretty quiet when your just prowling around.. i wanted quiet and thats what i ended up with when i got the force 2's.. if i had 3 chambers i would really be bummed out with the sound..

when i got the catback i had stock manifolds and stock H pipe and i wasnt impressed at all with the sound.. you will want your money back if you are staying catted with 2 chambers.. I;m guessing that 3 chamber with offroad H will sound like a 2 chamber catted...

I'll tell you though.. i couldnt be happyer with my 2 chamber, its not loud enough to piss off neighbors when you idle out in the middle of the night.. but its loud enough with an equal sound to make you happy.. .. with some of these glasspacks out like magnaflows they are really loud and dont really have defonition to them.. just loud and annoying in my opinion.. look around to find your noise!.. hope this helps..
