I have a 3" system with 3" electric cut outs on
my Rampage.. you will still have a drop in power
but I cant say how much that is.. so with a 2 1/2"
you will have a bit more drop in power over the 3"
If I install the cutout in the 3" portion and use a 3" cutout, will it still hurt performance a little bit just from the fact that from the cut out back would be 2 1/2"?
Your MAIN concern is your mufflers.. you can find
some mufflers that have very little back pressure
..if you get that right you wont even really need
the cut outs.. I dont know if you are concerned
with noise but some muffs have great noise control
and low back pressure... do 2 tests on every set
of muffs you try.. a DB reading(noise) and a back
pressure reading.. that tells you how well they flow
