I just installed an Invidia catted downpipe a few days back. On initial start-up there was some smoke and a terrible smell (which I think was the WD-40). I am not currently running a heatshield becuase the stock one wouldn't fit, but I ordered a turbo blanket and it should be here any day now. for the last few days the car has smelled pretty bad, but slowly getting better. Just today when I got back from work (3 days since install) I went to go do a slight boost, 80% throttle at 3k (with my stage 2 eco tune + SF). At 80% throttle I could hear the air (intake), but there was no extra power. It felt like a hose was not connected and air was just shooting out of it doing nothing. I checked the hoses and everything seems fine. What do you guys recommend I do? By the way on start-up there is also a gasoline like smell (Different from the first smells I was having which smelled like plastic burning).
