Yep. My homemade "Y" was the exact same way. Still did it later when I tried to go back to a single exhaust and put my Y in after a H pipe. I ended up bending my H and made a smoother, better Y. Still didn't do a thing. There's a weird resonance in the exhaust where both sides come together.
A 2.5" Magnaflow oval glass pack took care of it nicely. Their glass packs are straight through perforated tubes so they flow nicely. My car has that with a Flowmaster 40 in the very back. I have a nice deep grumble at lower rpm and more of a v8 sound when I step into it. And NO MORE RASP!
I'd recommend the Magnaflow right after a good Y
