2.25" vs. 2.5" X-Pipe?
 

Any benefit in one vs. the other?

Word on the street has it both will work. Also, any specific brand? eBay one for 40$?

Big Difference …..you'll be happy...

what engine? what's your intent?

you could always measure the pipe where you plan on installing it and then just match that size. could also be about the same price to have a decent local exhaust shop make/install one for you.

.... I went in to my muffler shop and asked them how much it would be for an X pipe for the x5 he said around 4 to 500 is that normal

Sorry guys car is a 6/06 4.8is!

We have the same go 3" if u want much better


Heres my Exhaust stages, different setups give u an idea

Thats a liiiiiitle too much for me. Id like to keep the stock mufflers and everything else. I'm just looking to slap in an X pipe.

Could you post a link for the ebay xpipes?

The 4.8 has 2.5 exhaust. To maximize the performance benefit the X pipe should be 2.5.

Anything larger will be larger than the existing exhaust and won't work.

2.25" inlets, 2.5" outlets. Recommend Dr. Gas x-pipe
