if you need to wait to buy a glass pack, wait and have all that stuff welded in at the same time.
im guessing you still have all stock pipes and need to have it welded in.
or you could save the shop costs and get a new Y pipe and then have a flange welded to one end of the glass pack and you'll have all new cat back. seem the Y pipes for around a 100.
like this. then you can bolt it right up to the cat pipe.
and bolted in.
