What gaskets? I didn't see no gaskets! I installed a Europipe last weekend and didn't remove the muffler - I did it exactly as described by ard in post number 3, but didn't know to look for gaskets. Also, when I removed the 8 nuts holding the exhaust to the turbos, about half pulled the stud out with them. I couldn't get the nuts off the studs, so I just re-used everything. Should I retry and use the nuts provided by Europipe?Also - sidenote - my 60-130 time decreased by 0.1 sec after doing the exhaust. Does that sound about right to anyone?
I sprayed all the nuts with WD40, the day before, the night before and in the AM. I think it also helps that mine was relatively low miles and rarely saw water. If the bolts and stuff get rusted, more likely they will sieze up and potentiall twist out of the turbo flange.
(Tip- how to get a nut off a stud when it has backed out: Take two new nuts, put them on the opposite end of the stud, and tighten them together (this is a jam nut) Now they are locked on the stud. Soak the locked nut and see if you can get it off. Last resort is to cut it with a grinder, crack it)
I've heard both on the gasket- if it is in good shape, little corrosion around the turbo flange, low miles, you may be fine. I don't know what might happen if you have a bad seal.... I only replaced one, the dealer didn't have a pair in stock...
Anyway, I'd say your nuts are clearly 'lock nuts' now. Should be OK. Get new studs and nuts, gaskets perhaps, for the next time! Or just replace the turbos to get new studs!

The 'gasket' is a metal affair almost like a big O ring that sits in a groove in the turbo outlet flange- it is around 4" in diameter.
