Then one more ‘FYI’ for you - a modern free-flow catalytic converter reduces engine output by just 1hp or less these days. No need to bash out your cats or do a ‘cat delete’ to get more power out - or cause to ‘forget’ to replace them when they clog up/wear out, because they’re relatively cheap now as well.
Yeah. I don't worry about Cats. I have done cat-back exhausts before, but that was over 20 years ago. What I have has no need for performance goodies, or for me to take anything off. But if I did it again, it'd be either too old to need cats, or new performance where I would just work around them. I have Bugatti dreams on a Yugo budget...
