cat converter question

[Accord R33]

realy then whats your opinion

without getting into the detail of backpressure.

my opinion on your question is that you get a high flow cat

i ran no cat since the day i installed my previous H22. with the rest of the exhaust stock, it hit an annoying tone between 3500-4000 but sounded fine otherwise. idk where you guys are getting the idea that itll burn up your valves and completely kill a stock motor?

We don't have emissions testing where I live, but all "non-stock" exhausts are illegal and ticketable for about $80 a pop. I like performance and not getting pulled over, so I have gutted the cat on every car I've owned for years. It costs two gaskets and gives at least as much hp and acceleration gains as a $500 exhaust, doesn't make anything rattle or sound like ass, just lets motors breathe in the upper rpms and raises the volume level when you're getting on it. my accord, prelude and 240sx have never had problems with codes, valves, torque, etc., and neither did my '94 integra with no cat from 80k-188k mi., a deer killed it. Engines can also supposedly suffocate from oil clogging the ceramic element in the converter. Safety mod?

I have heard that you can burn out exhaust valves just running no header at all for a long time. But thats what I heard. We recently did it to a diesel merc here and sounded like ass plus we only ran it for like 2 min to get it on a lift. But as for with a header and straight piping it back I dont see how it would burn the valves as some people mentioned. And dunno if thats the same link as the one posted a while back about backpressure in one of the threads.
