Best X-Pipe Location on 5.0 XKR
i'm doing the resonator delete and adding an X-pipe in tmrw am. I assume that the best place to install the X-pipe is where the 2nd resonator is (closest one to the rear axle), or is there a more affective spot in between the 2 resonators? Thanks for any input.

Put it where Jaguar did.

And make sure you get the right size

Old-timey hot rodders (like me) used to put a mist of white paint on the exhaust pipes, and where it turned the brownest was 'supposedly' the best place for an (at the time) H-pipe. Reasoning would suggest that using the old wisdom that an X-pipe would also be in that location.
Is any of this accurate? Hell, I dunno.

OK so I just went out to measure my exhaust pipes. Now I have a 2012 XKR convert with the $1400 performance active exhaust option. Stock system. I measured the down pipe after the cats and it was 2.368 ". Note as it goes into the main pipes it necks down. The OD of the pipes from here into the X-pipe and back into the back box (muffler) is 2.175 ". Pipes look new yet and they are round so these measurement were as close as I could get it. Just an FYI

Well I had mine at the back to start with & found on overrun most of overrun noise was in headers & seamed to be not allowing gas out quick enough. So had it moved to the front & it transformed car throttle response & made note deeper & sounded amazing on overrun ! Now pops & bangs lovely on overrun. Also repiped rear silencer inside so it was the same as the XKR-S rear box. Now it’s a real Jekyll & Hyde Now in dynamic mode with Exhaust valves open !!

When it comes to OEM, production and assembly methods create costs that also factor in to that compromise. On top of that there is design time, also a cost. Spending extra on each component delays release, costing in both engineering time, and lack of production/sales with the new design.

It's kind of funny. On my old Lincoln LS with the Jag 3.9 AJ from the factory they combined the mid pipes in the form of an X pipe under the trans by hydro forming two sheets of stainless, only they didn't connect the pipes. Further back where Cambo's pipes have the X, it had a 3/4 main diameter 'H' connector and then a pair of X100 style mufflers tucked up behind the wheel well.
When I redid that pipe I did a 2/3 port opening X pipe (like I did in my build thread) and ran the rest of the way back with 2.5" pipe and finally a pair of Pypes turbo style mufflers. That car sounds ballsy for a little 3.9 NA engine. I wanted more of an old school E type sound so I went with glass pack style mufflers at the bumper and smaller 2.25" pipe feeding them. It has a very distinct sound as well.
