Are the UFC10 and UCF20 exhausts compatible? It looks like it from the part diagrams and numbers. I need the parts to put a 98 LS400 exhaust back to stock, and older parts cars are much easier to find around here.

Anyone swapped these parts over?

they are not compatible. first the exit on UCF10 mufflers are straight out vs turn down like the UCF20s. also the mid pipes will vary. i've looked at them together and they have different flanges and hanging points, but this is not to say it might not work. with little "customizing" you can make it fit.

Thanks for the info. Do you know if the 95-97 are the same as the 98-00?

the only difference i know of is that the mid pipe on the 95-97 has a weird Z pattern on it while the 98-00 doesn't. the flanges and hangers are the same so it should work!
