So I currently have a muffler/resonator delete. I really like the way it sounds but cold starts and WOT is starting to annoy me. It's getting me a lot of negative attention on the roads from cops and I'm starting to become that "*******" neighbor when starting my car in the morning. Recommendations for something that is not as loud but still seeexxxxxyyyyyy? Been off the forums for a while so I have no idea what the latest is.

I'd recommend putting a resonator back in.
I have just a muffler delete and love the sound.

Cold start is alittle loud, but once warmed up sounds like stock until you start driving. Driving is very smooth and tame.

Yeah I have a muffler delete, but I like it. I agree with belac, just put the resonator back on. If anything you can just get some mufflers to slap on also. That will reduce the drone in your cabin when you start up and drive in the 2-3.5k rpm range.

Do any of you how the HKS Hi Power compares to a res/muffler delete?

I do not, but there are some youtube videos. Here's one with a res delete:

I think HKS makes the car sound throaty, which I like. I would have ordered an HKS, but they don't make one for my model (IS-C), so I went with a muffler delete instead

Buddy had HKS on his 2is. Pretty loud. But im sure it's quieter than your current setup.
