Deleting the cats... 50-state legal!?

[Racer-x]

What if you could delete your cats without getting hosed for not passing emissions?

I don't personally have emissions in my state (FL), but I do have some pros/cons about cat removal...

Pros:
1) The noise
2) The little bit of performance gain
3) The throttle response and feel.

Cons:
1) The noise
2) The feel can be a little more 'rumbly'
3) The smell...

So, what about having the best of both worlds? I wanted to find out about an electronically-actuated butterfly-valve system installed in a cat bypass pipe that is welded into place next to the stock cat, rather than in-place-of.

A system like this would allow you to push a button, in essence, and open up the car's exhaust system for a much more aggressive sound. It would be, if nothing else, a great parlor trick.

OK, so, my search led me to this:

It's a start, and I'm gonna find something closer to what I'd need, but this is a great general idea (only problem is that this one is boost-actuated). We need electronically-actuated, so I'll keep my eyes peeled. Let's do this!!!!!

Easy, Remove the Diaphram style actuator from the one shown in the link and buy an electronic actuator from autoloc.com....You could buy a switch to replace a dumby button around your console and run the wires to the actuator. You try it first then let me know how it works out for you.

You'd have to buy 2 actuators and 2 butterfly pipes for this to work.

it'd be cool if the switches could say Race/Touring.

You're totally right.. I didn't even look at the pictures to note that the actuator wasn't built in!

Heres the link to just the butterfly valve with no actuator and no TEEpipe

$139, bet you can buy these from summitracing.com for cheaper than 50 bucks...plus the ones on summit are welded at an angle so the air flow of much more smooth instead of straight.....BAMM down!

For the record, I'd just like to say...

muahahaha.


Also, thanks CJ for doing the hard part for me :P I had to talk to my lady for a little while.

I have mixed emotions: I love the idea, I'm definitely going to do this, and when I do you can expect a video, as well as other info... I may even go the route of making the diverter switch bypass even the muffler when activated! (hence the muahahha).

My sadness is this: I didn't invent it. lol.

Really, thanks though. Throw out some suggestions.. I think this is something a lot of people might be interested in. If not, I'm way off. lol...
