I meant to mention - most of the 370 exhaust setups also direct fit the new Z with the rear hanger bracket reversed.

thanks for feedback - but i’m not concerned with drone or db levels of an open exhaust on na and even less on a boosted setup.

v-bands are king. slip joints cost less and provide a cheap solution to prevent fitment issues.

with that said - you can provide an affordable product to folks. nothing wrong with that

3” lowers delivered from houston, tx.

the inlet flange ID is the the smallest, the inlet tube end is necked down but much larger than the inlet flange. The outlet flange ID is close to the same size at the tube ID.

Yes - Jet hot is nearby so will probably go that route.

I have a local powder coat paint house that advertises thermal coating for turbo housings. Going to call to see what they are using.

I'm not very impressed with Jet-Hot to be frank, but if you go with them make sure you do their 2000F Extreme (link below) and not the 1300F Classic. The Classic will flake off at turbo temps (been there done that).

Cerakote is the better product for turbo & catalytic converter applications.

Glad to hear this, a local guy uses Cerakote and priced my at $200 for my set of LDP's from spool. I am debating if it's worth it.

My opinion is yes. Do it right, do it once. But...$200 is perhaps a bit high (maybe he'll negotiate?). I paid $120, but after adding in shipping you're about net even.

I've personally used shops in Dallas, Houston, SoCal, M̶i̶n̶n̶e̶a̶p̶o̶l̶i̶s̶, and South Dakota. Happy to share contacts if anyone wants them.
