Got offered a 250-60 PS, 360-80Nm k04 setup. What kind of difference might an exhaust mani make?

Default Got offered a 250-60 PS, 360-80Nm k04 setup. What kind of difference might an exhaust mani make?

I thought some tuners thought this was an essential part to get over the 240HP barrier?

What they offer is:

K04 (I suppose 015, maybe slightly modified)
Install kit.
380cc injectors and software
70mm downpipe
Pop-off Bayleys or Forge
High Flow 200 cel cat
FMIC
Bigger MAF housing.

As options they also offer:

Silicon intake pipe
Full 63.5mm exhaust system
Sachs Race clutch

No talk of an exhaust manifold whatsoever. What do you think?

Sure sounds nice. Might as well put a new mainfold in since you're there anyway.

Default Pardon my ignorance. Does that read "plug and play stock mani is better than ATP H/F stock mani?"

and what does H/F stand for?

Sorry about giving you so much work :-)

Isn't stock mani supposed to make turbo spool faster? Isn't the upgrade only better for the top end?

Default in the very least gasket match the stock manifold.
