Hey guys I want to put a hi-flow cat on my car. I already have a magna flow muffler. What are u guys useing? Also will this make the car more loud? And will it affect my 02 sensors at all?

Im using SLP high flow cats, and there will be no sound change at all, and no it wont affect you 02 sensors.

So do u think its worth doing

Hey guys I want to put a hi-flow cat on my car. I already have a magna flow muffler.

Go to http://www.installuniversity.com/ins...sity/index.htm , click on 'library', then Catalytic converters flowed on a flow bench (data) to see some cat flow data. Generally, metal flows better than ceramic.

What are u guys useing?

I use Random Tech cats.

Also will this make the car more loud?

Absolutely, if you get a good higher flowing cat.

And will it affect my 02 sensors at all?

The front o2s will function as normal, but you will run a bit richer due to the loss of backpressure. You'll see a gain of a few HP, but will need to tune them in to maximize the newfound flow rate (like headers). The rear o2s will sometimes set codes on higher flow cats. You can trick them or tune them out to eliminate the SES light.

It's not a cheap mod, but every little bit helps in the long run.

What are you wanting from it? There are cheaper ways to make power, if that's what you're looking for.
