Anyone replaced their air injection tube before? Any insight to what I can expect in terms of extraction and access? Mines rusted through at the cat. and don't really want to spend the winter months driving with my windows down.

Thanks in advance fellas

 

when i had my new exhaust put in i had to mess with it, it looks like it has 2 pieces to me but mine popped off behind the motor and it is a pain to get to, but i got mine on in about 1 hour but like i said, on my 88 i have one pice that goes down and then another piece going out to the cat, hope this helped
