Exhaust and Intake

I'll be changing jobs in a couple of weeks and my commute will go from 3 miles to 60 miles each way. I'll be spending a lot more time in the car so I am accelerating my plans to mod the 650. From what I've read in this forum, the most cost effective way to improve my exhaust system is to remove the resonators, add an x-pipe and maybe a couple of hi-performance mufflers which will, hopefully, give me better sound and have nicer looking, to me anyway, tailpipes. Am I on target here?

Second, I think an intake would be a nice addition, but have read not so positive things about the AFe unit, which is a lot less expensive than the Dinan unit, which I haven't seen any reports on. Does anybody have any real world experience with either?

I decided to put new wheels on hold until I burn through my current set of runflats and will decide then whether to go for 19's or 20's. Wheel selection on the 650 is kind of complicated as compared to other cars I've owned. I'm not used to having to be concerned with offset.

Oh yeah, I want to upgrade my intake and exhaust to improve my MPG!

I feel for you with the commute - mine is roughly 35 miles each way. Some days I'm sitting in traffic and some days it is open highway (just depends on the day!) I also occassionally make the trip from DC to Charlottesville, VA, which is a nice 85+ mile trip (each way) along country roads.

I alternate between my 650 and an SUV that I have. I love taking the 650 on the Charlottesville run as I can put the top down and really enjoy the car. I deleted my resonators and really like the subtle change in the exhaust note that comes from it. It's noticable without being over the top.

Good luck with the mods and with the commute.

Thanks. Did you remove all the resonators? Did you keep the stock mufflers?

My commute will be a 50 mile straight shot down 95. Just have to worry about snowbirds and the occasional hurricane.

So no one has installed an intake?

Funny - my commute is 35 miles up 95.

I had all three resonators removed and left the stock mufflers. With the top up and windows closed, you really don't hear much of a difference at all - certainly no droning in the cabin at cruising speeds. If you punch the throttle, you will hear some increased sound. With the top down, it is more noticeable (in a pleasant way) but isn't obnoxious or over-the-top in any way.

Intake/Exhaust

Shtaka, I suggest that you talk to Peter at http://roadnrace.com/index.shtml in West Palm before doing anything to the car. he knows BMWs well, and has worked on my previous cars as well as my partners race M3s.

If you need tires, I like Ernie Bello at Bello Motorsports in West Palm

I just bought an 09 650i. If you are heading past 45th street between 8:45 and 9:15 on 95, look for me heading north everyday (I live in Wellington).

I will probably doe the x pipe route, but from what I have read, the intakes loose torque but gain upper end horsepower, which defeats everyday use.

many go with the rpi scoop, but I have not seen that dynoed.'

I am just starting to mod mine as well.

mjposner, thanks for the referral. Peter is not too far from me, so I'll drop in and visit.

My brother lives in Wellington. I'm there all the time. What color is your car?

I have the same impression on the intakes, except for maybe the Dinan, but I haven't seen anything posted by anyone that actually has one! At around $1000 plus installation, I want to know what I'm buying.

ob2? Are you planning to drop the front bumper to install the grills? Matte or gloss?

I believe that the grills can be installed by removing some torx screws up top to allow you to reach in behind and unclip grills.

I went with these: http://www.ebay.com/itm/271072807164...84.m1439.l2649

I did this in ten minutes on my 08' M3.

I thought about getting the dinan intake too just cant justify the price if it also looses low end power.

well looks like im ordering both today since the sale. I've thought about the ess supercharger and gearing too.

anyone have the supercharger and how does it run against say gt500, or m6, vette.

Here is where i'm at. Get a supercharger and mods or just keep it as is and get a older 964 / 993 996 or supra or something. hell ls1 rx7

I don't care about the mpg **** I would by a prius if I cared about that. I'm used to the 2 a week fill up's. that being said put 10k into this thing or get a ls1 rx7, 993 / 964 / 996 or something of the sort to play with.

Grecco, I may be old, but I new boy meant fried, just effinn with him.

I have had dinan intake, throttle bodies and stage 2 software in my 2000 M and to be honest, not much seat in the pants improvement.

Really the best thing to do is pre and post dyno work.

It sounds like mixed reviews on the performance improvements from a new intake. To the guys who have installed them, did they change your MPG at all? To me, that's another measure of how well an engine is performing.
