Thumbs up X5 4.8is Exhausts on 4.4i

Well to my fellow BMW enthusiasts i would like to say that for the past 6 months since I purchased my 2001 X5 4.4i I have spent countless hours acquiring info on mods and tips off this board so now I would like to contribute a little.

I wanted to change the factory exhaust on my X5 4.4i but wanted the huge Oval tips factory look, and after lookin around at the aftermarket brands like Supersprint and Eisenman I felt that I could get by with the 4.8is OEM exhaust and save some money in the process..

Now after constanly harrasing my dealer techs and the good folks at pacific BMW (Edward) no one had a definite answer (they were like well oh..., you see..., we really can't.... what had happen was...YADA ..YADA ..YADA..)
I decided what the hell I took a chance and purchased the 4.8is exhaust and decided to do the upgrade.

well as you will see on the pictures the 4.8is exhaust is shaped a little different from the previous M62 engine cars, the curving is a litlle different also.. the muffler shop I took it to only had to cut a small portion of the pipe because the 4.8 was thicker at the end and repalce with another piping to fit my car .. otherwise pretty easy install took less than 1 hour to do job.

As for the response it took a couple of days to kick in but at startup and when its in idle you get a deper growl,

theres no other feeling like having it park in front of Starbucks backed in and remote start from the inside on my way out hearing the start up growl and hearing it Purr and seeing people staring ..

Well one of the reason that I chose the 4.8is exhaust instead of the 4.6is exhaust believe or not it that the 4.8 exhaust is about $300 cheaper than the 4.6 and yes the tips are included. so I paid $900 for the exhaust including the rubber mounts from pacific BMW

Overall I love the look and the sound and some and people coudn't understand why I spent the money on an exhaust when you really don't get much HP gains, but the joys its brings me is priceless

Looks good, and good to know it's that easy to put the 4.8 pipes on a 4.4. I've got the same year and engine in my X, same color too, really like the add-on bumpers on yours. Nice ride!

I DEFINITELY understand. The joy of a mod done right is nothing short of PRICELESS. Congrats on sticking to what YOU wanted. There is no better satisfaction than a great mod bringing daily joy

Good job! It's never about need, only want, especially when it comes to cat back exhausts. Coming to terms with that early is much easier.

nice job. At least now i know it is possible.
i have a 2004 4.4 and I wonder if the conversion for me would be a simple bolt on instead of a mod like you had to do on your 01 4.4. So the only parts you needed were the exaust and the hangers. did you need anything else? Does the exhaust bolt into the resonator. and how did you handle the different sized piping.
Thanks

4.8 exhaust on 4.4i

You have the N62 engine and I have the older m62 engine the pipings and angles may be the same . worst case scnenario the muffler shop can weld the pipes to fit the openings to your resonators if the 4.8 exhaust pipes are bigger than your 4.4i.
go for it its a nice project also get the the 4.6/4.8 is valence and side caps, and aluminum brushed running board to complete the look if you don't already have it . pm me if you have any any more questions

Sorry i am new to this board and do not know how to PM you. I do have some other queustions though. Did the exhausts come with the tips. and how much better did the exhaust sound. Was it louder deeper. If you have a sound or video clip that would be great. Did it feel like you gained or lost any hp. If you are standing behind the x5 while idling is it a noticible difference. Do you wish you went after market or are you glad with the stock 4.8 exhaust.

did you say you paid 900 for all the parts you needed. any more info would be great i want to get a new exhaust asap. I am tired of the old one. I really want the 4.8 exhaust especially for the tips. I want the dinan but i do not like the four smaller tips i like the 2 larger tips better.
Thanks in advance
