Yes I see what you mean, that sound is just right. What brand X-pipe did you buy and what diameter is the piping for the X5? The guy in the video went with Magnaflow, they show three different pipe sizes.

X-Pipe 2.25"

Guys one more question

I am looking at the super-sprint exhaust.. Planning to buy it for christmas.. I just noticed that everywhere people are selling/buying the 3.0L/4.4L/4.6L one.. and even mounting on the 4.8is.. I noticed Super-Sprint has 2 systems.. one specific just for the 4.8is..

See below

1.) Supersprint BMW E53 X5 4.8is Sports Muffler 90x85mm Oval Tips : Bimmerzone.com ---- SPECIFICALLY FOR 4.8is (OVAL TIPS)

2.) Supersprint BMW E53 X5 4.8is Sports Muffler 4x90mm Round Tips : Bimmerzone.com --- SPECIFICLY FOR THE 4.8is (ROUND TIPS)

3.) Supersprint BMW E53 X5 3.0/4.4/4.6 Sports Muffler 4x90mm Round Tips : Bimmerzone.com -- FOR 3.0/4.4/4.6


I see the 4.8is exhaust system seems looks like it has fatter (bigger) pipes .. my question is - can i install the 3.0L/4.4L/4.6L system on the 4.8is?? or do I have to get the 4.8is system??? will the 3.0/4.4/4.6L system with rounds tips work perfectly on the 4.8is? anyone have any experience with these two different exhaust systems models ?? and what is difference between 3.0L/4.4/4.6L and the one made specificlly for 4.8L?? I cant seem to be able to find out any info on pipe width on these two different systems..

no not at all....alot of us have 2.25 on pipping as i bliv..but if that..maybe "some" cars 4.8is will have 2.50" which is still ok to install your MOD......you only see 3" on cars over 400hp ....you should be ok...

pnoyako85 so you think the 4.6is system should be fine on the 4.8is right??

.. Im thinking if the pipe is a bit smaller gasses would flow faster & might actually make for a better sound?? What you think??

If you look at: BMW E53 X5 Exhaust | Let the Thunder Roll From Your E53 Exhaust

Seems there are 3 different systems I can go with..

1.) SuperSprint
2.) Eisenmann SPORT
3.) Eisenmann RACE

out of the three which would you guys recommend?? someone was praising the Eisenmann RACE as one of the best exhaust systems for the 4.8is.. Can anyone confirm???

I can get the supersprint for the 4.8is at $1700 while the Eisenmann RACE is $2400.....

What you guys recommend & think is best to install??

For the Eisenmann there are stats - SEE BELOW - no stats avaliable for SuperSprint.. Which system would you guys consider superior & far better sounding??? Eisenmann or SuperSprint??

pnoyako85 I think I found my new Christmas present...

Check out: Eisenmann BMW E53 X5 4.6 is - Race - YouTube

Look at the videos of the 4.6IS RACE Eisenmann... I think that video just made my decision for me :) ... and probably on the 4.8is it will sound even better...


I'll try to be there Dec 2nd my dood... I'll make every effort to be there I promise.... I got a family event that day but I should be able to make it.. I'll confirm with you prior to the event.. If for any reason I cant make it Dec 2nd then next time and food/a drink or two are all on me :) hopefully by next time you see me my Eisenmann system will be on :) or something better... I removed the resinator but I want mooreeee lol :) fkin love the engine of this beast I want it to growl like it never did before :)

youll be happy with it man..... i heard this one already..it sound awesome...........what do ou have 4.8is?...

Yup I got the 4.8is... . I see parts everywhere for the 4.6is - not so much for the 4.8is.. Wonder why....


Like i mentioned before someone posted a supersprint system on ebay dirt cheap but its for 4.6is not 4.8is.... I looked up info and the 4.8is supersprint system has bigger pipes compared to ther 4.6is... I dont want to restrict air flow any way so I'm stuck between either buying the freken super-sprint for the 4.6is and mounting it on a 4.8is or spending some more $$ and going with the Eisenmann Race...

pnoyako85 i'll private msg you by end of week re: dec 2nd. I will def try to make it brother...
