Dinan High Flow Throttle Body 3. While you have the engine apart, you could do a little porting and polishing of the heads. Also, the m62 makes much less power, and is not forced induction, so I would go with 2.
I had a question about the Dinan intake; are oiled filters a requirement? Good luck with your future mods. The m62 can get real raspy with just pipe too, so I would recommend a xpipe to even out the sound. I think the headers will require a tune and the X-pipe should increase scavenging.

I like the route you went with doing everything except the exhaust; to me, the stock exhaust sounds decent but I have never been one to be in love with a loud exhaust. Then I do agree that above 4k or so to the newly raised limit, it screams a bit louder not that the 550i Sport with the performance exhaust was particularly quiet in that range to begin with. Excuse me, but I'm a newbie in the tuning world. I've been looking but couldn't find anything. Just from what I have read from past dinan 5's and what the power listings on the dinan site I thought 40hp was quite aggressive for the mod list.

If I can get 35-40hp off for 3k and still be warranted. I would even say the car has smoother power delivery and shifting now than before not that the shifting itself is smoother because it doesn't do anything to shifting but that the power out of a gear and into the next is smoother, thus making the shifting appear faster, stronger and smoother. I'm doing the first two, first then doing the tune later. That is a beautifully done car.
I decided to purchase a Dinan Free flow exhaust to open it up as well as replace the trapezoid looking tips for some quads, however I'm still a little underwhelmed with how it sounds even when I open it up. If you do, definitely let me know how it goes, if you dyno'd it pre and post, where you found them and what it set you back. Would a high performance exhaust be louder?

The S1 suspension is just sick! I understand where you are coming from completely. Prolly looking in all the wrong places. I would think the Dinan options would be the best route to explore, however, from experience, the 550i out of the box for straight line performance is very competitive with anything at the track. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. Some days are dedicated to certain themes, see below. Thats a whole other conversation as to whether or not that causes any issues with the motor.
Also, they do provide a bit less filtering. I do intend on dynoing since the upgrades, just have to find a good local shop to do it. The seem to offer a huge seat of the pants feel. We'll see I must say it's a pleasure to drive! But is there anything else, looks like there are a lot of things on 535's but i cannot find anything really on the 550i, please help.
