bmw 325i Headers

I have a buddy who is coming to Dallas from Mexico for the holidays and he is bringing his 2009 bmw 325i. He want's to upgrade the headers and maybe cats. He was going to do the whole supersprint system from headers to muffler but changed his mind. Is there any other solution to aftermarket headers then supersprint?

2009 325? Is there a Typo somewhere? They stopped making the 325 after my year; which is 2006.

If its a 325 or 328; you should look at Craven_328's headers he is selling. I bought his muffler and honnestly, I couldnt get a bigger bang for my buck.

in the US they did,
325's and 330's are still sold in other countries, along with a plethora of other engine choices

True that. I saw Dallas and pulled the trigger. Shame on me.

But the point is: The same headers still fits

What other company makes headers for the 325i other then supersprint?

The 2009 uses the same header and front cats/connecting pipes but a different resonator and rear muffler.

Gavin-
Have there been any improvements made to the headers, or does the the motor mount still require some degree of modification? And have you perfected the O2 sims?

O2 sims are 100%, engine mount ive found to be dependent. In a 328 it needs a mod, on a 325 we got it to clear, 330 havent tried yet.

Either way a slight modification is a small price to pay for 20hp

wait you live in florida and don't know if you get tested for smog? In short no, florida does not test for smog. Nor do they do any road worth inspections what-so-ever.

Here you go, this one still had the tune in it, and had to modified after this dyno to compensate for the new hardware, so that low spot isnt there anymore - i just dont have access to the recent dyno's with the changes
