Well the Axleback is very small .. like 1.75"

I think the rest of the exhaust is 2.25"

But where the axle back meets the mid exhaust, where the axle back is bolted on. What size do you think the flange is? Does anyone know? Or where can I find that info

call the service department at any Lexus. They might be able to help you.

Might want to try looking at sewellparts.com.

Yeah I did both. Dealer says their computer doesn't say anything about size. Just gives them part#

Yeah thanks, it looks like the diameter is 2 inches. Are you modifying your axle back?

It's a 2" donut flange. I'm looking for them too, hard to find.

Hoping someone with a stock exhaust will just cut the pipe off the mufflers and sell that way.

I spent an hour at the exhaust shop this morning looking at it with the guy. We can flare a 2" section of pipe and then slip a flat flange over that to hold it but I decided to wait a couple weeks and try to get the factory pipes from someone that doesn't care about them.

Good luck!

Yeah I have been trying to find that type of flange and its hard. I only found it in 2.5" and it was $50. I don't want to cut and weld because my car is leased also and I don't want any trouble when I turn it in.

Weird, small muffler shop right down the road from me took one look at those flanges when I brought the car to get a straight axleback made, and they said "Oh yeah, we got flanges that'll bolt to that"

Didn't realize they were hard to find.
