Magnaflow Tru-X Pipes
 

Hey I am looking to install this baby in my 3.0L X5, just wondering what size of dual inlets it suppose to be? 2.25? 2.50? 3.00?

Thanks

2.5" is the current piping diameter on your e53.

Thanks man ! I am putting the order thru right the way

Try to post a video after you get it done so we can all hear it.

Sure, BTW the price on the X-pipe is about 84 dollars.

Yeah, it can be an inexpensive mod granted you find a place that welds them on nicely and without leaks for a decent price. It can be a nightmare if you take it one place that does a poor job, then to another to try and fix a mistake only for them to cost you even more money out of your pocket....

If I could do this mod again on my x5, I probably would've waitied to gather up flanges and gaskets...asked the muffler shop to put flanges on my xpipe and old resonators...so I can switch back if i need to or if I sold the car without the xpipe..

Charlie,
Do you have OEM muffler with your X-pipe? You have a 3.0, right? I have just the Remus on mine, and it's pretty tame on the 'lil 3.0i. Sure would love to hear how your X piped X sounds compared to just the Remus with the stock resonator.

Good advice, thanks man.
Hmm, so where should I get flanges and gaskets from?

Hope it's not too late, but it is about 2.25", not 2.5"... the OEM piping is metric in sized and the 2.25 is the closest match, and a tiny bit bigger in diameter as well.

WOW, I am screwed-.- I got the 2.5..........
