can't find it on their site it still brings up regular 40 series so I think they probably still make what I need.
from measuring looks like my truck stock is 2" inlet and 2.5"
so I need an original 40 sereis di/do 2" inlets and 2.5" outlets
any help is much appreciated!

the above part number at summit racing is a regular 40 series with 2 1/4 in/out. it's a single muffler. and i have never heard of 2 in 2.5 out.
I did two regular 40's 2.5 in/out on my 97. dumped in front of axle

ya but my stock pipes going into the stock muffler are 2" and the single coming out is 2.5"
so I need the di/do muffler to offer the 2" inlets I could go with a smaller or larger outlet but perfer 2.5"
or should I order 2.25" inlets and slide my 2" pipes in it and just weld it and forget about it lol don't see how that could hurt anything really
