Do what I did.
I bought the flowmaster 2.5" into 3" Y pipe, and took it to a reputable exhaust shop.
They fabbed up downpipes from my shorties into the flowmaster Y, which they then connected to my 3" cat.
Looks and works beautifully.

Re: Flowmaster merge pipes?

A flowmaster merge and a flowmaster? after factory cat merge. It has the correct bends to weld right to the rear of the factory cats.
