Hi Ferdman... i forgot to mention I did use a dremel tool later on... that too didn't have an angle to reach the other bolts. I am thinking of using the dremel to cut the pipes at the ends of the cat about an inch before where the bolts/gasket are fused(shown with a red line in the picture). However... I am not sure what piece do I need for the dremel. As in.. what cutting instrument? i rarely use the dremel... so info is greatly appreciated.
