whats the different in magnaflows #'s

[BornSticky]

i bought the magnaflow 39006 cat for my car but right after i found the 33006 and it is almost exactly the same but 50 bucks cheaper..... whats the difference?

33006 is a 3 way muffler that's slightly narrower than the 39006, which is a 2-way

so would the 33006 work better for my car cause it is narrower?
wouldn't 3 way be better then the 2? why does it cost more then?
im a bit worried i have to much flow with a 2.5 exhaust if i could i would change it for a 2.25

[SuperK]

I would say a 3 way would be better... but I'd be wary of them magnaflows. mine lasted a couple years and pleh'ed.

Think I'll go with a walker next time.

thanks for the info

it also shows that the 33006 is the first part of a 2 cat system (T2) and the 39006 is a 1 piece (T1)
