Does anyone know of a vendor that sell's an x-pipe already welded together. I've only found kit's to weld your own from borla.

 

nope, I'm pretty sure no one makes one, and I read somewhere the oem system acts as a giant x pipe already

 

I know but the oem has 3 resonators.

 

i hope you got on that group buy for the ppe headers for our cars.

I didn't. Do you have any information on them?? Is there any way to remove the rear converter in the y pipe without getting a check engine light?

 

y pipe as in the one after the sec cat/ resonator, that connects to the rear axle back? those are just 2 resonators. and you won't get any cel. as they aren't monitored.

 

I'm fairly sure you could remove it without throwing any codes as there's nothing monitoring the last one (i.e. no oxygen sensor plugged into it).

 

Ferri did u do an x pipe if so results? Apprecite it

 

I am going to try and post some pics of the x-pipe that I am currently building.

It will cost about $350-400 and requires a bit of cutting/fitting/welding (you could do it considerably cheaper if you used mild steel and started with a "muffler shop" Y-pipe or even the stock one).

Parts used:

- Megan Racing SC430 Y-pipe

- 2.5" X-pipe for 06-up mustang.

I looked at the pics and the angle looked close, so I ordered both parts, when they arrived I laid the X-pipe over the megan piece - it looked like it required only a small bend on each side to make it line up.

First, I cut the "Y" out of the megan piece but before doing that I welded braces across the flanges at the front and then across the pipes in the middle to keep everything aligned. I also drew an outline on the floor - it's not critical at this point because once bolted to the car I will do final fitting before welding. I am also going to add high flow cats and at that point I will tuck the y-pipe as far up as possible for ground clearance.

I used one 90deg. stainless elbow and cut it into a pair of 45's, next I welded them to the x-pipe (they are only tacked right now)

Next, cut the required angle into them to mate up with the megan pipes - once I bolt it up to the car it'll just be a matter of cutting the Y out of the catback and mating them up.

Yeah, I could have made this all from scratch - I did on the other GS I have and it probably took me a whole day of cutting/fitting/welding - but this time I wanted to "cheat a little" and it probably took me all of about 1/2 hour to do it.
