If your car has less than 80,000 Lexus will replace the midpipe for free at any dealership..Invidia midpipe will not work with the awd model unless you do some modification...All axle-backs for the 250 and 350 are the same

I just got mine fixed. Got 144k miles. Took the heat shields off and welded the holes up. Temporary fix but its a lot quieter now! I'm looking for a new exhaust system too ... any recommendations???

Mine failed inspection because of leaks around the heat shield. Dealer wanted $900+ for the parts alone never mind labor. Took it to a exhaust shop, they took off the heatshield (****ty design as it captures salt and promotes corrosion) cut out the affected section and welded in about 12-14 inches of new pipe, cost $240.
Oh, and this had to be done on both sides because there were microleaks on both sides.

Same Leak: Removed Heat Shields. is250 2008 AWD
I removed the heat shields on both sides of my exhaust after it developed large cracks in a perfect ring where the heat shields end. The shape must retain moisture or something. I applied some exhaust tape over the cracks and after 1 day, so far so good. I am wondering if removing the heat shield is okay, or if I'm going to hurt my car.
Is the heat shield to block heat from the undercarriage of the car? It seems like it's engineered more to retain heat on the exhaust pipes. I feel like with the heat shield gone the air passing underneath the car would remove heat faster than with the heat shield.
I read that it is to warm up the exhaust and cats faster, but I've also read it's to stop your car from melting in sensitive areas. Does anyone have a definitive answer? From a heat transfer perspective it would make sense that it is engineered to heat up the exhaust faster.
Above the heat shield that is on the exhaust is more heat shield material that I assume is sufficient for stopping the exhaust heat from harming the bottom of the car.
