I recently just purchased a Lexus ls430 2001 with 205000 miles on it. I bought the vehicle for 2000$ and have put 2000 miles on it without a regret. However now I have decided to redo the exhaust since its leaking and too rusted to weld. I'm having trouble finding the OEM Y pipe and it seems difficult to do without that so if anyone has any tips or suggestions let me know.

 

I'm also planning on doing a custom exhaust I've just noticed most people weld to this Y pipe.

 

some people have had good luck with the non-OEM RockAuto exhaust pieces.
