I took my car to a muffler shop and was told the exhaust leak was in an EGR tube at the accordion part. I called Lexus parts and they said there is a short tube and a longer tube. At this point I do not know which one is the problem. Can you describe the replacement of both? Lexus wants around $200 each for the tubes and $14 for 1 of 2 gaskets needed for each tube. I found online parts stores selling the tubes for around $115-$123 each and gaskets for $2-$3 each. I also heard that the tubes might be repairable (via brazing or cutting out bad part of tube and somehow reconnecting? Can you expand on this as well? Thanks, Rich

My Friend, Listen, Don't Mess around with Exhaust Problems--What is you or one of your loved ones life worth?? Carbon Monoxide is Colorless, Tasteless, and has no smell! By the time it is ingested, it is too late--someone will die! Order your parts online with the gaskets! You save a few bucks! Take the parts to a reputable Muffler Shop and have them do the repairs! Not just any shop, because Muffler Shops know all the Smog and Exhaust Particle Laws, and if you are in California, they are really strict, even on the way they want the parts welded together! Now, you are going to have to pay some bucks for labor--because--you don't take Hamburger Meat & Buns to Denny's and ask them to make you a Hamburger, do you? O. K. I hope you do the right thing my friend!
