None of the exhausts on any of my cars have flex joints. And I’ve never had an issue. I dont believe in them.

ya know what, now that i think of it, my m3 doesnt have any either… i guess in a RWD layout it doesnt need it… because the rubber mouting points can absorb any flex in the engine mounts…
i was used to making headers/downpipes for FWD cars where the header has to go under the motor and you need one there

the motor doesnt have to be taken out to install… he was putting them on with the car on a 2 post lift.

A header install on a 350z isn’t exactly easy, and this looks even harder, but it is definitely do-able as long as you are competent.
Most people will tell you that the gains from headers on 350z are not worth the hassle, but I think this system definitely looks like it is worth it.

Sounds great. The EVO manifolds we made sounded similar as well. They were equal length 22" runners and merge collected. I love that sound
