Exhaust spacers

[spoondog]

Sorry if this has been covered before but I can't find much info on it.
I have just installed the Teraflex 2.5 lift with Fox 1.5 to 3.5 shocks on my 2015 manual JKU, looks great and drives great. Now as expected the front tail shaft hits the exhaust before full droop is achieved which is why I also ordered the exhaust spacers (Yet to be installed) but I have been reading on some U.S. sites that people are having issues with the exhaust hitting the crossmember or hanging too low when using the spacers.
So has anyone used the spacers on a rhd JKU?
If so have you had any issues?
Will an aftermarket bash plate still fit?
And aside from a new tail shaft what are others doing to prevent contact once they've lifted their jeep?

I have spacers on our jku (with the same lift actually) and while i dont seem to have any problems as such, i think im going to change the whole exhaust at some point.

It doesnt seem to hang low, and while it seems to have clearance, i do now get a rattle under some conditions, not all the time.

I would assume comments saying it hangs lower would be because they didnt slide the joint further downstream into the next section enough (to be honest i think it is my issue too). I just had a hard time with that, so figured near enough is good enough and sometimes get a bit of contact towards the rear somewhere.

If you already have them, id fit them. You can always take them back out if you dont like the result.

Thanks Wombat. That's good to know.

Having recently bent my exhaust crossmember to a point where the crosspipe was touching at early acceleration (and creating likely the same vibration Wombat mentions), I've now removed the crossmember in preparation for installing an ARB skid plate system, which as a general start point in its instructions suggests the removal and disposal of said bent crossmember. The kit comes with shims for the rear bolt attachments to space the plate away from a lowered exhaust, but it will slightly affect ground clearance at the bottom of the plate - less so if you have a lift installed already.

Please note, this is no the transmission crossmember, but the exhaust crossover, I think found only in the automatics.

The manuals have a crossover too. They all have to at some point to join the two pipes. Im not aware of there being any differences between auto and manual pentastar exhausts (although there could be, im no expert)

Forgot to mention earlier, i dont have any aftermarket underbelly stuff so not sure if the affect fitment of such.

NTRubicon is referring to the crossmember/bashplate that is only fitted on automatics directly below the exhaust crossover. I have synergy spacers fitted and still have the above mentioned crossmember in place but i had to 'clearance' the exhaust crossover slightly to clear it. I also removed part of the exhaust heat shield and reshaped the exhaust pipe directly below the driveshaft for clearance as my shocks are 27.5' long.

I really don't like the spacers probably because i have the same rattle mentioned earlier so they will be coming out and a stock exhaust going back in as soon as the stock driveshaft fails and i upgrade it instead.

Gotcha. Thanks for the clarification
