325i bolt ons?

Ok guys so i want to do a little upgrading to my 01 325I, i was going to go with a set of ebay headers, and was wondering what you guys thought about a CIA and cat-back exhaust, I've read the headers are the most restricting part so i was wondering is exhaust is even worth it, but in the aspect of sound I'd like to have a little more rumble, will the headers get me there? and as for the CAI I've seen on the threads that the factory box it pretty well designed and I wont gain more than a HP or 2, but what do you all think? all three? just headers and exhaust? just headers?

Look into the m54b30 intake manifold swap very nice gain above the 4000rpm mark

Headers are a must. Get a long tube CAI. Those will gain some hp. Get magnaflow 16533. Those are some options

Ordered my headers today, did some research on the m54b30 intake manifold swap, seems like you need to get the car tuned from what I'm reading? Also anyone have any luck with a sprint booster they advertise the difference as being night and day

I have m54b30 swap with no tune. Also I've read that sprint booster makes the pedal more sensitive meaning better throttle response, better on an automatic than a manual, reason being its too sensitive. Also may I recommend buying a shark injector instead of sprint booster. Might gain some hp and also better throttle response

Nice how big of a difference can you tell after the intake manifold swap, and I was thinking shark injector would probably be just as good or better than a sprint booster

I think you would need a 330 tune or something to run those injectors
