X Pipe

[4.6is Ryder]

I'm looking to purchase a X pipe guys...anyone seen any deals out there? Since I'm going to be doing the brakes within the next 2 weeks, figured I would pull the resonator and add the X pipe at the same time.......Phil

$80 - Magnaflow - summitracing.com

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

The local shop I got the pipe installed said it's a 2.25" pipe and charge $200 out the door.

What does it sound like?

Is it very subtle?

Yes, IMO it's very subtle - but definately noticeable. I'd consider it a small change in sound and volume - most people won't even notice.

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.

X5Jay, does your exhaust sounded like marbles in the pipes at higher RPM's after the X pipe mod??
Read the thread above to see what I´m talking about:

How about long time reliability, can this X pipe deliver a proper exhaust back pressure, at very high RPM??? All of you that made the X pipe mod didn´t thougth about this question?

I am interested on doing this mod, but I´m afraid of ended like MrLabGui. He took out the X pipe and went back to stock resonaters.
Is the X pipe just a crossover pipe, if so, i think a good shop can make this X pipe fo less than 80 usd.

No marble sound at all with mine. I do get a slight bit of gurgling and popping on a cold day after I've shut the X down for a while and then re-start and drive off again - but it's a good sound, not a marble sound at all, and it doesn't happen in the warm weather at all.

As for the back pressure question - I believe that's what the X-Pipe's designed to do - add a bit of back pressure where going with plain straight pipes wouldn't do that. As mentioned in my little write up, the sound change is very subtle compared to stock, but it's certainly there - a little deeper and sportier IMO. No change in power - not more and not less.
