#43083 is a 80 series.
Don't know if anyone really cares, just thought I'd mention it.

25 - 2.5"
8 - 80 series
2 - center in/off center out
4 - unknown
30 - 3"
8 - 80 series
3 - off center in/out
This one is a 40 series delta flow.
9 - delta flow technology
4 - Unknown
30 - 3"
4 - 40 series
2 - center in/off center out
Hope this helps

Ok guys why argue over this subject? Flowmaster claims that the 80 series muffler in a stock 82-92 fbody(350) will create 30hp and 40lbs torque. You don't get claims on a 40 series like that (for our cars anyway). So go with facts not fiction. I have an 80 series on my car and if it's any quieter than a 40 it isn't enough to justify. Nuff said.
hahaha if you believe those claims, I have a bridge to sell you...
get whichever one you think looks best.... the single outlet flows and sounds better.. the dual outlets look better. take your pick.
