on the early models YES, but on a 96 it is not bad. about 3 hours...
You do not have to remove the transmission or even lower it, but you will need to remove the passenger side catalytic converter as there's no room and not a suitable tool made to get at it the pipe fittings. When you do this, you'll probably break at least one exhaust stud on the manifold. Be prepared to drill it out if necessary.

my 95 LS has an exhaust leak up by the engine too..and it makes sputtering noise when you give it the gas or upon cold start. My mechanic who works at Park Place Lexus said it could be a cracked manifold, bad manifold gasket or gasket connecting manifold to exhaust system. His labor to change out gaskets is the same whether he changes out manifold or not. My question is..what are the chance the manifold is cracked? Is this a common thing? The part at Sewell is $465.00. The mechanic recommends I have one on stand by in case the original is in deed cracked. I am looking at used ones online which one around $125. The noise is coming from passenger side.
