Oil Filter problem

When I would tighten the collector to my TTI H-pipe it would pull the header up slightly and bind the oil filter in and prevent it from turning. I had to loosen my header and collector bolts to get the filter on and off. After that I went with a 90 degree adapter. You'll have plenty of people on here who will tell you you don't need a 90 degree adapter with TTI headers but I needed one.
