Re: removing cat converter
What is your ride? That will depend on whether you have O2 sensors after the cat or not.
Stainless steel saves weight. It is a better insulator than the stock material so it keeps the exhaust hotter and velocity higher. It will also make a raspier sound at high rpm.

Re: removing cat converter
changing the exhaust downpipe will also mean your pre-cats will be removed too.
removing both precats and your main cats will mean your car will be much louder, and your exhaust much smellier, but if coupled with a freer flow intake, can make your car much more responsive. but you can give up any hopes of passing any inspections.
whether or not error light will come out depends on if there are any lambda sensors after the part you have operated.

Re: removing cat converter
u can remove ur cats on the E60..no problem. in fact..change ur headers and exhaust too. ur throttle respond will be instantaneous. insulation in the E60 is good as well..but there will still be a notable difference in sound. expect some resonance...and irritated neighbours and their dogs.
on another note..wanna buy stoptech brake steel hoses? pm me if u want.

Re: removing cat converter
2 cats....2nd one is between headers n muffler. removing cats...is a serious decision. it will make ur car very loud. but ur petrol consumption will go down at least 1.5l/100km. throttle response is almost instantaneous though. at 1700rpm..u will hear the raspy sound.
