Upgrading the Exhaust of the N54 Z4

[pbondar]

Hopefully high quality for the price..should go nicely with the TTE500 turbos and revised plumbing

The end result.☺

I think it looks nice and it still sounds very civilised, you only hear a difference when you go full throttle.

In two weeks the next stage: Downpipes with racecats and silicone inlets.

Reviving this topic. I'm also interesting in doing the same as I think an X pipe would help the sound a lot.

How much of a difference did replacing this section make to the exhaust note?

Hi carabuser,
Sorry for the late reaction, not that much on this forum anymore.
Sound got a bit deeper and raspier (but i am on race-cats in the downpipes and retained the oem secondary cats), but not a great difference.
Did pick up around 5 hp if I remember correctly, but everything depends on the rest of the mods you have done.
