secondary air injection pipe

[1990LTD]

Where does this meet the exhaust system?

[85crownHPP]

At the cats.

[1990LTD]

Before the cats, so they all get air, or on one side, into one cat, etc? thanks pete

[85crownHPP]

Actually Im not sure for yours... On my 85 they go right into the cats... on yours I want to say they are in the rear cats.

[1990LTD]

cool, thanks. won't be running to (or from) anything soon enough

[gadget73]

Mine go right into the pipe before the secondary cats

Yours is a 90 right? might be a 90-91 change. I was thinking about my 88 because its leaking there gotta take care of the draw 1st...

[chitownvic]

Yea Pete mines a 90...They probably did change it cuz I was surprised to seem them there too....Im used to the air tube going straight into the CAT....I was under there yesterday solving the Fluttering and leakage problem..Some nice heater core hose and some clamps..and now its flutter free......YAY!!!!!......The air tube was rusted off where it meets the pipe all the rest of it is in good shape surprisingly....

[85crownHPP]

that heater hose is gonna melt... they make 3/4" emissions hose, its sorta pricey.

[chitownvic]

Nope..It is emission hose.....I just called it that so mangs would know what I was talkin bout...My brother "Took" a roll of it from a garage his friend works at LOL

weird....when my 91 had pipes going to the cats, they went straight into the cats. I only had two, tho.
