Single Exit HKS Hi-Power vs. Dual Exit Greddy EVOlution GT

Tomei 80R is out of the question. I had this exhaust for 3 days and it was too loud for my taste. To give some background I have a tomei UEL and a JDL ultra quiet over front pipe. I would like to stick with 3inch output solely so I can match the rest of my exhaust system. I currently have a perrin 3.0 resonated exhaust installed. I do like the sound of it and I can hear my supercharger whine, I'd like to get more of a boxer rumble so I guess a deeper tone. My concern is since I had a LOUD experience with the Tomei 80R. I don't want to come to buy another exhaust and then have to try to resell to try to recoupe the cost. So hopefully I can gain some insight from the community.

I'm looking either at the HKS Hi-Power single exit since it's a 3 inch (technically 2.9~, close enough) or the Greddy EVOlution GT. After some research I found out that this was a new exhaust that is also a 3 inch inner diameter.

Anybody have a preference? Which one is louder? Which one is deeper? Which one do you prefer and why?

thanks for everyone's help!

Have you considered having something custom made? You could have a midpipe with multiple resonators to help keep the drone down and pair it with a vibrant muffler.

Resonator:

Muffler:

I have the 2.5" inlet version of that muffler, its a tight fit, but does fit.

I have heard the HKS with headers in person and it sounded great with the silencer in. Without there was some drone but not super loud imo. Granted everyones definition of loud is different so ymmv.

I have not heard the GReddy so cant give any input
