Is removing the catalytic converter a good Idea? I dont have emissions where I live so that is not an issue. Will I gain power? What are the pros/cons?

Thanks

I wouldn't bother. If you were turbo charged....that'd be another thing, but for na motors.....they're not hurting anything, assuming they're in good working condition.

Yeah, helps if you have a turbo (as they don't really like or need backpressure) - but with N/A some amount of backpressure is needed, I believe it helps with exhaust velocity...

Well, backpressure is the enemy of exhaust velocity, and the entire exhaust system. You want as little backpressure as possible, with the greatest velocity as possible.


Don't worry about removing the cat. You won't really gain anything other than some sound. If you want the benefits, you can get a high-flow cat, but I would recomend retaining a cat.

Don't bother.

But on a turbo car it would not hurt the exhaust valves correct? Would only help right?

correct. Turbos love free-flowing exhaust systems. Backpressure gives the turbo something to fight pretty much all the time. It's definately not good for spool-up or maximum flow through the turbine.

So, turbo + cat = quicker to burn turbo
N/A - cat = quicker to burn exhaust valves
