Need some info on Catalytic Brand?
Welding tips and Catalytic converter buying advice
So here are the questions (I have searched up and down the forum!):
Catalytic Convertor Brand
- “Davico” is out (not a good brand).
- “Bosal” seems OK, long history of quality.
- “Magnaflow“: $80 for the cat alone vs $300-400 for the direct-bolt in.
- “DEC” (aka “Diversified Environmental Catalysts”): I have had good luck with this brand on my BMW in the past.
Catalytic ONLY vs Direct Bolt-in
It seems that most people here have good luck with Magnaflow:
BUT how long does this (Magnaflow stand-alone cat) last given the fact that it is welded to the existing piping which itself is 13 years old?
The direct-bolt-in: who has used it, what brand do you recommend?
Lastly, the O2 sensors
At 110K miles (No CEL codes). Leave them alone or replace them?
