Blazer Exhaust

I currently have a 1999 chevrolet blazer with the vortec v6(4.3L) with a v-force muffler on it. I love the way my truck sounds but i wish i could get it louder. My friend works at an exhaust shop so i am going to get duals put on. His boss doesn't want to make a Y pipe because i am just going to split it off after the muffler, so i need a dual outlet muffler. Without straight piping it....any suggestions on a muffler i could get that will be extremely loud but still sound extremely good? let me know please!

best option is probably going to be a dual exit flowmaster original 40. i think that muffler is 3 inch in and dual 2.5 inch out. idk how your current muffler is installed but you can use a reducer to go from the stock 2.5 inch pipe (right after the cat flange, before it reduces to 2 1/4) to 3 inch then slide the muffler onto that and run your 2.5 tail pipes. this is the setup my friend is using on his 95 2dr.
