So are you guys saying that there is only a flange gasket on the passenger side or that's the only one with a tendancy to leak? I had the dealer replace my stock h pipe under warranty about a month ago. I've had it in 3 times because of it leaking and stinking up the inside of the car since and they claim there's nothing wrong with it. I'm thinking about giving up and just going under there myself to deal with it, my guess is that it's the gasket that they didn't replace originally.
Hope I'm not hijacking the thread, just thought you guys could lend an opinion. Thanks
