Just wondering if anyone knows if megan test pipes for a sc430 will fit a gs430? My 2002 gs430 is pulling a p0430. Catalyst below threshold bank 2. My car does have ppe headers

I have added the link below
Any help would be greatly appreciated

have you checked for leaks in the exhaust to rule that out first? the cats are pretty bullet proof in our cars and last a really long time... there are tons of threads on this and usually its an exhaust leak at the flange or leak in the y-pipe...
