Hi All,

I am having 2006 Lexus GS 300 which is having exhaust leak in the midpipe(close to O2 Sensor), I visited Monroe auto they suggested replacing the whole exhaust as the pipes are not in good shape to do the welding & even if they do welding Issue will resurface pretty quickly at other places.
I need the comunity help to find out what are the options I am having to change the exhaust midpipes(any aftermarket exhaust's & How much it will cost to replace it).

Response will be highly appreciated

The entire midsection is roughly $1,500 (17410 in pic)

OE is the way to go if your only other choice is welding slag metal to your exhaust.
I know there is an aftermarket (performance oriented) mid-pipe, but forget what it is at the moment. For my $, I'd go OE, but its not the only way.

This is not a common issue for the GS I dont think, I would suggest a visit to a decent muffler shop for a second opinion and look at the actual location of the leak etc....

Thanks for your reply's.By any chance can any one suggest a good exhaust shop in NJ(I live in central NJ)

Is it possible that it is a ratle and not an exhaust leak?
EyeKutr is correct this is not a common problem. Any major work done to the engine? Maybe the gaskets where it connects to the manifold flange are not seated properly.

This is a common problem especially on the AWD. Mine did the same thing, a visit to a muffler shop, they removed the clamps and just welded the pipes back together. No issues whatsoever and only cost $25 bucks.

Make sure they remove the dust shield as those are the cause of the rusting.

I am also having exactly at the same place (under the dust shield's) for my GS300AWD.

I had the same thing,apparentiy its covered by the exhaust warranty, I took mine to dealer cause I kept getting the check vsc light come on, shops were telling me its the o2 sensors I changed em it still kept coming up wit the same code so I bite the bullet and took it to the dealer and they replaced the pipes

Isn't the stock exhaust stainless steel?

BinaryJay

No. The pipes are not stainless they are your typical rust magnets.

By the way I replaced all those clamps, the clamps themselves rusted to nothing and do cause an unsettling pinging rattle sound when they are not seated firmly. Hardware store stainless ring clamps for a dollar or so each solve that problem.

Thanks for the gr8 feedback & solutions.Today I visited another exhaust shop & He did recommend to cut the pipes & replace them with new pipes on both sides(as I am having 6-7 leaks & lot of rust on the pipes).I agreed with him & gave it a shot.He did cut the pipes after O2 sensor & Before CAT Converted & replaced them with new pipes.It costed me 300$ out of door.

This is good info. I just started to notice that my exhaust sounds weird. I cant explain how it sounds but definelty different than stock.

$300 to last 1 to maybe 2 years.
You put an expensive band-aid on this situation. A fix befitting a Ford Taurus, not a Lexus.
If you still have the car in 1 to 2 years, it will creep up on you again. Just be prepared for that.

Simmsled, what would you have rather done? open to suggestions. I am in the same boat
