De-Cat a non turbo?
Been reading about de-catting a 156 2.0 TS.
I may be wrong but this is what it seems it takes.
A set of 2.5 manifolds. Because they didn't have the cat. I'm not sure how the V6 manifolds would fit.
Slightly moving the Lambda back as it works better away from the heat. And can get a better reading.
And just having an exhaust place cut out the last one.
I am not to sure on this as people seem to have different ways of going about it.
Some people just say cut the cat out and replace with a straight piece of pipe.
The car i have is a '99 model. I don't know much about CF1, 2, 3. How would I check that. And what is the best way to de-cat without causing ECU issues. I have access to a machine shop, so just cutting my pipes and re-welding in straight pieces wont be an issue. As long as this wont harm the car.
More importantly. Does de-catting a non turbo car make any difference. This is the first non turbo car I have had and have always been told de-catting is just a turbo car thing. But if it will give me at least a 5bhp gain I may look at it.
Lastly is there any other ways to get a bit more out of the car without opening the engine or bolting on a turbo.
My main goal is to get a bit more grunt on the pull off.
Thanks guys. Sorry for asking a question i have seen asked a lot. I just have no idea what the CF thing is or miss understand the 2.5 what what.
