Didnt really see anyone making a aftermarket part thread or any intro thread to any of these newcomers that want to pursue this part in their x3's. i'd just thought we'd post pics here and post our opinions on different kinds of aftermarket parts to x3's. As far as any of the categories go (exhaust, body kits, lighting, and performance) i can only think of the couple that i was educated in the e46 (3 series) forums such as: remus, eisenmann, uuc, rogue engineering, seidl tuning, gruppe m, hamann, acs, the ever popular dinan, technik engineering etc.... Personally here are the aftermarket parts i've found for the x3's.

i really hope we can get more pics of aftermarket items for the x3, some of us may like modifying some of us might now but theres something for everyone in the aftermarket realm, maybe we'll see the other side of us x3 fanatics :yikes:? well, enjoy!! :thumbup:

Digging this one up from the past, but any updates that people know about?

I'm looking into an exhaust for my X3; something that's not too loud in the cabin at cruising speeds.

$300. You guys think this is a real remus exhaust? Bavauto sales it for $500+ I think.

I believe the eBay exhaust will require welding/modification. The one for $500 or so is a direct bolt on exhaust.

Infinitas GmbH (ASA off-shoot company) has a SC system for X3 as well. Link here (http://www.infinitas-gmbh.de/shop/product_info.php?cPath=34_28_62_63&products_id=273).

anyone actually install a SC on their 04-06 x3? If so chime in for feedback and experiences...

had to dust this thread off.

I searched fairly diligently and was unable to find any available engine upgrade parts for a 2008 X3 (260 hp motor). Would like to do headers, catalytics, muffler, airbox & reflash. Those sites that responded to inquiries stated that there was little demand for these parts and, consequently, nobody manufactured them.

I've been wondering if certain aftermarket parts for vehicles with the same engine would also work for the X3 -- maybe parts for the 328i or the X5 3.0si. Check Will Turner's site, for example, for the 328i:

http://www.turnermotorsport.com/html/show_category.asp?txtsearchParamCat=E90

You might be blazing a trail trying to fit some of these bolt-ons to an X3. Then you can let us all know how things work out!

i read someplace that the 3.0si being so light just isnt built to withstand forced induction. That may be another reason to explain the lack of power mods. Maybe there aren't many gains to be made on the 3.0si

IMHO none of the "add on" stuff is worth the money--you won't get much in the way of a performance increase with any of it other than the really expensive supercharger kit. Only changing the wheel/tire set up might be worth it to get a different look. The X3 is already pretty well set up and thats why you don't see much for them (also because the number of X3's on the road are relatively small). I recall my son setting up his G35 with literally everything under the sun only to be sadly disappointed when he ended up with only a very modest increase in power--at best. Save your money guys !!!!!

A skid plate would look nice but I've never seen one available.

Looking to "Blaze a trail" in fitting aftermarket parts to a car that they were not intended for an an adventure one should be reluctant set out upon. Great risk to the wallet. Given that nothing really serious will go wrong with the usual bolt-on applications, the danger is that the performance parts, purchased and installed at great cost, must be removed at additional cost and the stock parts reinstalled. Loss of use of the car, aggravation at getting nowhere and having to somehow resell parts you can't use. The wrong parts will cost you as much as the right parts, assuming you could get them. Let someone else spearhead the charge.

A high performance, normally aspirated engine will not see major performance gains. For the X3, a full exhaust system, airbox and reflash, if and when available, will probably produce at most 20 to 25 rear wheel horsepower. Figure $6000+. Assuming 20 percent loss factor in the drivetrain, the X3 makes maybe 210 rear wheel horsepower, so this is around a 10 percent gain. Is it worth the money? A matter of opinion.

I am interested in making my X3 a fun every day driver that I can occasionally track. Since I don't haul kids or much else in it I have stripped off about 700 lbs. The handling is much improved and so is acceleration, 0-60 in under 6.5s with no suspension or engine mods yet. Can't wait to finish it. It sits very high at the moment.
Question- can I expect any HP gain with muffler replacement?

A good rule of thumb is that a free flow muffler (catback) is good for about 5 horsepower.

I've got the Dinan pkg on my '04 3.0 MT (non-sport). It includes CAI, free-flow exhaust, and engine s/w. Dinan cliams 13 hp & 11fft/lb torque (IIRC). The improvement is noticeable, but not dramatic on a 4000# car. The exhaust is sporty around town, but not particularly load, and is trnsparent at cruising speeds. Interestingly, mpg went up 1-2 mpg in twon & on the road

I'm in Santa Fe @ 7000', so I'm down about 22% in HP due to the altitude so teh Dinan stuff helps a little. I'd like a super/turbocharger, but bang/$$ doesn't make a whole lot of sense to me. All n' all, I've been very happy with the X3, will likely get another when this one goes off CPO in 2010, especially if they offer the 3.0 TT diesel or gas motor.

I suspect that most of the power increase claims made by aftermarket mfg's are somewhat optimistic. Such claims are, at best, backed by results produced under the most optimum conditions rather than "real world" conditions.

Any comments regarding chip upgrades on the 3.0d?

There is a lot of aftermarket chip upgrades of all sorts available. But how safe is it (not to do damage to the engine)? Is it worth the while?...

I drive a 2006 X3 with the M3 sport package. I added the DINAN Performance Engine Software (Product Number: D900-31X) and just ordered the High Flow Throttle Body (Product Number: D760-3300A) with the Stage 3 Engine Software (Product Number: D903-31X3). Is that what you have?

I think the stage 1 software upgrade was worth the $300. I'll let you know how the High Flow Throttle Body and stage 3 DINAN software works out.

Honestly, I have been looking at the Audi A3 for several reasons lately, and mods are one of the major points.

APR offers a chip set that gives a 61 bhp increase right out of the gate at $600 installed and tuned.

Dinan about 15bhp. Not impressed.......at all.

Couple that with a full exhaust around $1200.

You can see by modest expectations a 100 bhp increase.

And you have a serious contender with very little effort.

Plus, unlike BMW that tries to void its warranty at every opportunity the dealers will even do the installs.

Tomorrow, I take the X3 to Car Max to see what they will offer me and then off to Audi to test drive.

Remembering of course that the A3 is a turbo engine and the BMW X3 is not. hence the wide disparity between chip results from the two companies. I would also be concerned about the longevity of the high output modified turbo engine as well, at least in the long term.:yikes: That said, VW/Audi engines are superb and lend themselves well to "tuning" with great results. The new Porsche Cayenne V6 (2011) runs 350 hp NA and is the same unit used in VW and Audi, but "breathed upon" by Porsche.:D Let us know how you like the A3.:thumbup:

Drove the A3 and Q5 today. I didn't get to push it like I wanted because of the rain, but there is a marked difference with both models over the X3.

Q5- Very nice ride, extremely comfortable and handles pretty well. Not as tight at the X3 mind you, but the other pluses beat the X3 hands down at this point. I drove an AT and noticed NONE of the lag that the X3 AT has/had. If this had been around when I was shopping the X3 I would have bought the Audi.

A3 S line- Very nice ride, turns on a dime, love the paddle shifters, acceleration is very smooth and extremely fast. Seats are awesome. The dealer does not do performance upgrades, but DOES NOT void warranty for having them professionally installed.

Getting lunch and taking the X3 over to Car Max. If I can get $8k above what I owe it looks like I will be driving an A3 S Line. There is just no comparison performance, handling, comfort, economy, and price. Even trunk space is more. There is not the internal height, but I am not carrying wedding cakes.

If I can't get the pricing I will hold onto the X3 a little longer til I can build up some more capital.

Final word will be value returned on X3 and another test drive on Saturday with the family.

Sorry BMW you just don't cut it anymore :( when compared to other models.

Oh one more thing: 1.9% financing.

Now you know why the Audi folks are smiling these days. Have been getting all sorts of "collateral" from the Audi marketing folks (the wife has an A4) with all kinds of info (including a $500 cash card for service/maintentance). I am waiting for one of those from BMW but not holding my breath. Its her turn for the new car next so it will probably be an A4, although she loves the A5. No chance for the Q5:cry: she hates SAV's now (due to the awful ride in my X3).:angel:

Well bad news...Carmax that offered $1k above my wife's high mileage car's excellent price rating just offered me snot for my 18k mileage perfect condition X3.

Offered $24k with the original stock stereo back installed. Good KBB trade in is over $26k not excellent mind you. Good.

They said, "We have 68 already we can't get rid of and 43 of those are the 2007 AT".

BTW he knew right off the bat about the AT issue. They have a bunch of them and have had people walk off the lot after driving one.

Thanks BMW---are SAV's are worth crap.

I am going to see if Audi will give me KBB. If they will it's gone.

This only reinforces the need to dump it.

So for those who insist on buying a 2007 AT X3 check out Car Max in Laurel, MD they have them starting at $24k.
