junkin manifolds/cats for SLP's 3" need muffler suggestions

Right now car has manifolds and cats going to 3" pipe to a flowmaster single exit 3" muffler. I got some SLP 1 3/4" shorties and y pipe to put on it then im running 3" pipe all the way back no cats. Right now the exhaust is wayyy to quiet for my tastes and i hate the single exit flowmaster. How much louder will my exhaust be minus manifolds and cats? I want a muffler that flows good and has a 3" inlet and two 3" exits. I heard spintech is pretty good. I also want something loud.

I have headers high flow cat and 3" exhaust to a spintech and I don't think its very loud. Idle and cruise it's just a tad bit louder than stock but it does scream at WOT

The car is LOUD when you open the throttle.

I always thought the single outlet mufflers were louder than the dual ones.
