Aftermarket Muffler ideas!!

[ThaDannyP]

Hey guys. So listen, I'm 18 years old, about to go to college this fall, and you can imagine I'm not made out of money. Luckily, my dad is BMW-crazy and bought me my second car, the X5. I absolutely love it as you might guess.

So, I have a 2005 4.4i. I already have a Magnaflow X-Pipe on it. I LIKE the sound, but I need more from it. I have a few buddies with 4.8is exhaust, and one with Eissenman Exhaust. I don't have the funds for anything expensive, so I'm trying to find an alternative.

Do the mufflers need to have a 2.5 INLET DIAMETER?

On other BMW forums, guys have tried these "Euro style mufflers" from eBay, and they actually sound pretty decent. I'm wondering what you guys think about these things (I understand they're cheap), but I'm asking if anyone has any info on these/experience?

Will they fit? I've heard us X5 guys only have about 18 inches of length per muffler under the car, these are about 21 inches. Is that a no-go?
