There is plenty of room when truck is stationary. Only making contact when it's flexed.

See what Magnaflow says. I'm guessing they hook you up but if not have a local indy shop fab up a new piece. 30 minutes of work max so it should be cheap to do.

For a data point, my Magnaflow y-pipe is 1-1/8" clear from the right CAT to the driveshaft and 1-1/2" clear from the right down pipe at the O2 sensor to the driveshaft. No signs of rubbing and yes the suspension has seen its limits. Here is the left CAT where I needed to bend its flange/stamping where it once contacted the transmission x-support. How are your motor mounts?

I think my down exhaust pipes from the manifold are thicker than what yours appear to be Russell. I'm going in for belt change Monday and will see if I can adjust once up on the lift.

check your motor mounts like Russell says. I've had O2 sensor damage on the stock RRC y pipe due to soft/broken motor mounts. Big problem area with the v8's more so than with other LR engines in my experience.

Motor mounts all look great, surprisingly. Appears there just needs some adjustment. When I watch that area while the front end is flexed, it's about 1/2 inch too close. I'll see what can be done once on the lift.
The pipes on mine seem larger, and I'm sure the quality control could be off between pipes.

If I decide to take this off and do something else, what are my options?

I am going to address this issue and ask for a replacement from Magnaflow next week, but if they balk, what other options do I have for Y pipe replacement that others have no issue with? I know AB and RN have one, but has anyone used theirs?

Besides the contact at the drive shaft, I also feel that there is still a leak at the front connections. I am not sure this was so "direct fit".

Slacken the bolts on the motor mounts (both sides) and lift the engine (bottle jack under the pan with a piece of 2x4 to spread the load). When you start lifting the truck, tighten the bolts. See if that gives you the clearance needed. Otherwise Huff is available.
