Any exhaust I can buy and keep OEM downpipe?

I had the tsudo and the fitment was actually perfect, wickedly loud, but if you don't care about that, I would go tsudo

I had invidia N1 with stock DP, it was also fine

Right which is fine by me. I just dont understand what those side canisters are on the exhaust... Resonators maybe?

Those are Helmholtz chambers. They are calculated to a specific volume based on the frequency you are trying to cancel out. Usually to minimize or eliminate low frequency drone you hear at cruising speeds. I'm surprised the DC has them. Tells me there was some thought put into the sound. It won't affect airflow at all.

I've seen a lot of intake resonator delete posts but what about exhaust resonator, where is that located?

I ended up getting the dc sports. It's an incredible exhaust and I will have a good review soon with sound clips. I can't believe how awesome it is for the price. $420 shipped on ebay

Prior to the muffler

Seems like an easy enough thing to delete but would require welding. I'm sure less than $80 at an exhaust shop. Not sure if it's worth it though. I would recommend getting the muffler switched out for a better sound. Leave the resonator.

You could always get a 8th gen si oem axleback if you want to keep the same downpipe. It's not too loud from what I've heard.
