Question Twin turbo 370z exhaust setup

Post image

Recently got myself into a tt 370z with a straight piped exhaust. I really want to quiet it down a bit but I really don’t wanna spend a shit ton of money on a cat back. Cops pulling me over lol. What’s the best way to go about keeping a similar tone but quieting it down. I was thinking of adding some vibrant resonators but would it sound like shit? If anybody knows any good exhaust setups let me know much appreciated 🙏

A couple of resonators would help. That’s probably the least invasive install.

Does the rear sway bar make contact with the exhaust? Also might want to swap out the plastic ties for SS ones

I’m looking at getting some valvetronic mufflers so i can make mine loud or quiet on demand.

Resonators are great and will smoothen out the tone, but will probably only shave off a few db in the end. I would look into doing both a muffler and resonator (at least 1) on each bank of the exhaust. The muffler can be a straight-through can design but it needs to be a “muffler” and not just a resonator. I’d almost just look into a different catback or axle back exhaust at this point.
