It looks like an expansion bulb. I had one shop say it is a resonator and another say it is a pre cat spun and if removed it could mess up ecu, etc. It is small in size and is located on downpipe right next to oil pan.
Is it important to keep?
I have a magnaflow cat with a turbo muffler.
I am asking because it is a prime spot to add an additional flex pipe to help out my exhaust vibrations to rest of bolts and header.
Thanks!

it won't mess up the ecu. if your magnaflow isn't enough of a cat or working properly mainly it will give you a cel saying insufficient catalytic efficient code
it would work fine with out it. just make sure your post o2 sensor is behind your magnaflow cat or it will give ya cel.

ok cool I have both 02 sensors working properly. my downstream 02 sensor behind the magnaflow cat is a weld in bung due to universal cat
thanks for reply

no prob
I would say that magniflow isn't designed for that pre-cat anyway. it's probably not doing much since your not a stock cat anyway
