[98 A4]

98 a4 1.8 The flange on my cat came off and i don't have enough money to buy another cat so i'm going with the test pipe. the problem is that i have succussfully taken off the broken off flange from the turbo and i am having troubles finding enough room to take off the other bolts from the lower part of the cat. I took out the airbox and wheel on the passenger side to give myself more room but it doesn't seem to be enough also the bolts on the lower part of the cat are all rusted out and no matter what size of socket i use i just seem to strip the bolt all to hell. So i've tried everything on how to take off the bolts so i think my last choice is to cut them off. My question is what else can i take off the car to give myself more room to work with and what do u think i should do to get off the bolts. Thanks
