Decided to bite the bullet and replace the exhaust and cat of my sig indicated echo. I have running around a few years with a P0420 code and state emissions is 1 year overdue; car is up for registration in a year and won't be eligible unless emissions issues are addressed. To hasten the process the muffler broke and really not interested in driving around with a bumble bee exhaust.
The connection to the manifold was rusted to the point where hack sawing the bolts was necessary. The rest of the exhaust is hung with rubber hangers hanging from round stock attachments on the car.
Sawed the head pipe and removed the cat and resonator and 02 sensors; Removed the exhaust manifold as a mounting bracket had rusted and broke and the exhaust bolts remnants were still firmly in there. Manifold came off as if installed yesterday. Took a gander and decided just to order a new one. (OEM) I consider myself fortunate to enjoy such luxury; trying to revive the original one would have been labor intensive. Manifold gasket came right off and is tasked for reuse; Ordered some OEM bolts and gaskets for the new exhaust and some Denso O2 sensors.
Ordered an Eastern catalytic Eco III replacement converter and Walker SS Quiet flows or some such nonsense. Exhaust bolted up nicely and there were no fitment issues. I have one hanger issue due to rust, i have rigged it for short term and will be asking my friend's son to weld up a replacement.
Some poor quality shots.
Walker SS muffler
New convertor; engine to the right
Downstream O2
Connection between exhaust pipe and muffler
Manifold sans heatshield; (some really bad perspective going on there)
Took me about 6 hours over 3 weeks. Used Rhino ramps and basic hand tools and 4" Craftsman grinder.
Muffler $115
Cat $222
O2 Sensors $140
Manifold $142
About $100 of brackets, bolts, gaskets.
All parts from RA and Toyota online parts.
Pretty happy with the job, will be happier once the rusted hanger is replaced.
