I'm still on the market trying to acquire the ideal 2nd gen IS350 worth of its price and condition. A lot of the vehicles I keep finding are up there in mileage and age. I figure those with roughly around 150K+ miles have seen some driving and wanted to know aftermarket OEM styled exhaust manifolds with cats and if anyone has had issues with them as replacements? I would like to install PPE headers but at the same time I would like to pass emissions yearly without having to reinstall the factory exhaust manifold. Plus since a lot of them are high on miles and age I figure the originals are going to go out soon anyways.
