Ive got more exhaust leaks as well. The passenger side exhaust manifold, was a bad bad leak. I ordered a gasket from the dealership cost about $8.00 its going on tomorrow morning.. Had leak right under the turbo.. at the base.. we just tightened the bolts all 4 of them...also had leaks on the passenger side pipes where they connect at the "Y" joints.. we just loosened them and reattached and tightened, per Dan's advice.. We also used the smoke test method. Works really well! if theres any leaks the smoke will leak out in those areas.. hopefully the gasket will fix my check engine codes and correct my gas mileage, my computer is over compensating and pumping a lot of fuel due to the exhaust leaks..Will report back tomorrow after the leaks have been corrected..Also just ordered the stage 2 upgrade today
