Today I was at the Auto Hobby shop at PH. Putting my Invidia downpipe on. The part on the downpipe connected to the turbo has 5 nuts, but two of them the actual threads are not supposed to come out. As I was taking one of them off, I thought to myself that it looks cross threaded. But then my friend gave it a push and the head snapped right off. So Subaru cross threaded them out of the factory. I got the downpipe on. But now I have a nasty exhaust leak. Has anybody had this problem? Is there anyway Subaru will help me out on this?:confused:

I had to drive my car to work and got a check engine light and my cruise contol display was flashing on and off.

Yes, it sounds like they did cross thread it from the factory, and they should help you out with that. But seeing as how you've replaced your factory unit with a "Performance" downpipe, that'll prolly say no.

If you're worried about it, put the stock downpipe back on and take it back to the dealer. Have them fix it, take it back home and put your d/p back on.

Don't forget new gaskets.

All good advice, but this is key. When you first use an exhaust gasket, it crushes and deforms, filing up the tiny cracks and imperfections in the surfaces of the flanges it's in between. When you disturb that, it never goes back together quite right. Always use fresh gaskets whenever you remove and replace exhaust components. Unless small exhaust leaks after the turbo just don't bother you. ;)

Exhaust leaks causes turbulance, you don't want that. I had the same problem on my Perrin dp and the car ran worse than stock. You must fix those leaks, a new gasket at the turbo will fix that. However, I left my old gasket on the turbo side and placed a new gasket on the dp side. So I have 2 gaskets where the dp and turbo meet. There is a very - very small leak still. My friend said you should have taken off the old gasket completely and used only the new gasket. Anyone have suggestions? I did it because the leak was big. As for the donut looking gasket at the end of the mid pipe, I just left the old one on because the new and old gasket looked the same.

It's going to be tough getting the snapped stud out. Not a lot of room to drill it and get an easy out into the remaining bolt. Dealer should fix it, but I doubt they'll cover it under warranty.

The gasket thing with the crushing and filling in imperfections.... a little over the top. We're not talking microns here. A new gasket is not a bad idea, but the gaskets don't crush that much.. The leak aint the gasket, its the lack of nut on a broken stud.
