I have a slight exhaust leak in my lexus LS 400, how much would it be to get this repaired? Can I fix it myself?

probably around a $1000. and yes you can do it for a lot less DEPENDING on what is leaking... we sure dont know..

exhaust manifold and/or gasket or cracked EGR piping would be good first suspects, I would take it to any muffler shop and they will throw it up on the lift and find the leak and show you where it is, if it is in the exhaust system (downstream from the manifold mentioned above) - manifold leaks often exhibit themselves as a ticking noise that can sound like a valve tapping in your old chevy 350

replacing a cracked exhaust manifold or installing a gasket for it is a bit of a pain, most everything else in the exhaust system is fairly easy to fix if you have an oxy/acetylene torch and can weld with it. - It could even be something as simple as a hole in a muffler or in a cat.

probably the EGR pipe that's cracked. pretty simple fix. i replaced mine in about 30 mins. part was about $90 from the dealer.

Easy? Thats good to hear...I have noticed there are multiple methods for addressing this fix...which one did you use?

(I have a exhaust noise in the area...if it proves to be the EGR pipe I would like to try to do it myself, but some of the writups I have come across show it to be a major PITA.)

Please share...thanks!

I like Billy's method of just removing the passenger side cat

PS - the Lexus part numbers (for most years) are:

25601-50060 - EGR lower pipe $113.75 (wholesale mechanic's price)
25628-50010 - EGR upper gasket
25634-50010 - EGR lower gasket
