Hi all,
Just wondering if there are any noticeable power gains from a cat delete?
Reason I'm asking, we used to have an 80s Mazda 323 with a turbo i4. Turns out the cat was very restrictive and deleting it added about 20hp.
I know that old cats are very restrictive, so I'm wondering if this is also the case with 740s?
Before you tell me - yes I know this is against the law, but I'm just inqurying :)
