Part MPE-10790 = 2.25" pipe diameter Part MPE-10791 = 2.5" pipe diameter Somebody with a 4.6is is going to have to chime in as to what size applies. I have a 4.4i which takes the 2.25" diameter pipe. |

Question for you guys...how hard was it to weld the top portion of the x pipe? Is there enough room to work? Also, what size should a 4.6 take...2.25 or 2.50 x 12in..........Phil

What does it sound like?
Is it very subtle?

Well, I actually had a day off work today and just happened to be passing a local buddies' tyre and exhaust shop.
Next thing I know, its 2 hours later and the X-pipe mod has been done to my wagon! Basically as per other posts the centre siamiesed muffler has been replaced in this instance by 2 Custom Chrome "cherry bombs". Inlet pipe diameters were 2.25" and 2.5". Im presuming the larger inlet pipe on the one side is to take into account the greater length of pipe. First impressions are good. The sound is subtlely louder with more depth than before. Excellent...and the misses hasnt noticed Mod well worth doing if you want to retain the stock look.

Using 2 bulk/stainless pipes instead
Just got back from the shop where they recommended ordering a few feet of stainless steel pipe instead. They stated there's no gain in sound or HP from the X-Pipe (vs. cherry bombs or straight pipe) but that stainless steel would be necessary to avoid rotting and subsaquent replacement down the road (so avoiding ubercheap pipe is mandatory). They're going to cut and retain the flange connections so my rear exhaust can be changed as usual (without cutting). Lastly, they said a bender would not be necessary so labor should be low.
