Hey G....I wonder who made that CAI for you????

It was the 2.25" (the smallest diameter) MagnaFlow. They had to add reducer piping.

A X5 World member around here made my CAI box himself!! I'll be cruising back down to his place so that he can show me how to install the Angel Eye mod, (my last mod?), too!

Hey mtX5, I got back from Poland a while ago, and then moved into my new house. I read all the way through this thread and TY for all the youtube posts and pics. Truly inspiring. . . BTW my wife hates you LMAO! B-Day is coming soon and she never lets me down. She has asked for a parts list and over all price (i know i saw it spead out over the many pages, but just so it is all together). Do you mind?

And second question, say I do everything that you have done (love that sound) except the X pipe, is that a deal breaker for the entire system? What exactly would I be missing out on? Thanks in advance man!!!

Did you sold you exhaust ? If not how much do you ask for ?

glad to be of some inspiration

as for the parts list, basically you will need two round magnaflow mufflers, two tips of your choice (i might be selling my current magnaflow tips since i am putting 4.6 tips on) and 2.25 inch piping (not sure how much). parts should be around $475. I was charged $319 in labor. i don't know if these are the correct part numbers but this is on the invoice:
magnaflow tips - part # 35167 $105 each (i can sell you mine if you like them)
4" round muffler magnaflow- part#10415 $102.42 each
exhaust tubing 2 1/4" /inch - .36 cent x 168 used = $60.48

i bought the x pipe seperatly off eBay.. not sure how it would sound without it. if you want you can go with this setup, and if need be its easy to put in the x pipe..

goodluck and let me know if you need anything else

So MTX5, I see it's been quite a few months living with your Magnaflow exhaust on your 5 speed X5. I too have a silver 5 speed X5 and I'm wondering what life is like with it the exhaust.

I've been apprehensive about possible droning. I've had concerns about it being TOO loud. And I have the dreaded quart every 800 miles oil consumption.

I was wondering what have been the long term benefits and detriments.

haha life is great with it. no regrets at all. it is the sound i was looking for in and out of cabin. as i stated before, it is not quiet in-cabin, nor did i want it to be. i have no issues with oil consumption (just the normal amount i had before the exhaust system). the only thing i have noticed is a bit of reduced MPG. cant say that the exhaust system is to blame.

so all in all, long term benefits are same as the ones that led me to get it. can't say anything negative came out of it.. except the occasional few people who may say your exhaust is too loud lol.

I would guess the reduced mpg comes from giving her more gas just to hear the exhaust. Thats what I would be doing.

haha it is mostly from that

it really might be my driving, because when i drive 'fuel efficiently' it doesnt last more than like 30 min lol

Mmm... I dont think I'd care about the sound outside so much. But unlike yourself I only have 1 X to drive on a daily basis and I dont know if I can take the drone. Maybe if I dont do the X pipe it wont be as loud as yours.

If I could describe the perfect scenario for myself, I couldnt hear any discernable difference from stock with the windows up unless I'm really getting in it (like 4500k rpm and up).

A nice throaty bark is the "look" I'm going for.
