Hi
Assuming that OEM exhaust without cat will help for lower engine temperature, I am asking for advice. Please take a look at the following picture:

-Is it easier/better/possible to remove the cat through the window (along red line), or just to cut the pipe along yelow line and drill big hole?
-Is it worth/useful for achiving lower engine temperature?

Thanks for your time.
