Active Autowerke Sport Header E46 325i Review

[FalluccaE30]

Hello,

Has anyone used the active autowerke header on their e46 325i?  Are there any other brands you would recommend?

Thanks

Not sure about gains but they look much better than OE, the pics of OE look very restrictive.  I am using obd2 manifolds on my m50 because they are tubular stainless rather than the cast but I don't know if the bolt pattern is the same on my m54 heads?  If x52 manifolds bolt onto the head you would need custom downpipes made though.

I see,

Thanks.  I get all my work done at Kummrow, so I'll talk to them and see if I would need any other parts to go with it.

Probably need to do a secondary air pump delete right away. It's going to be a pricey job if you're paying someone else to do it. Honestly, with what you'd spend doing this you could just sell and buy a 330. It'd be way more of an upgrade.

Yeah...I hear you. I'm going to buy a e46 m3 when I move into a house with a bigger garage.  Also,  if I upgrade the current car, my wife doesn't care.  If I came home with a new car...I would be on the couch for a long long time.  Its a tough call because I have a lot into my 325 and when it was my DD I was rear ended and now the value is pretty low.  That's why I only track it now.

Thanks

If you must keep the car, you could always swap in a 330 engine. Cost would be less than the headers.

[FalluccaE30]

That's an interesting thought.  Where would I look to find one? What else would have to swap out to make it compatible? How much more would an M3 engine be?

An s54 swap would be much more involved and not worth it

[FalluccaE30]

If I did end up swapping the engine, could I put the 02 325 engine in my 91 318i?

[Earl]

You "could". It would be a pain since it is OBD2 and has some fun electrical components

Here's a link to a 325 to 330 swap thread.
