catless dp questions

[Flippercon]

Need to go catless so her is my question. I have seen all the different ones for the 9ths. I need one that looks like its catted due to inspections. It states a cat must be in place. Any vendors make a catless dp with the bump in it?

 

[Michal006]

You either get catless or catted DP. You might fail inspection with catless. Do they have emissions inspection in VA?

Catless

Catted

No emission test in the southern areas. I need it to look like the catted but be catless. I mean they couldnt just take out the guts?

I'm pretty sure it is mandatory to have a cat in VA for visual inspection. So @Flippercon will have to get a catless one and get custom metal fab look like there is a cat. You could remove the "guts" of a catted one but I have not seen anyone do this before.

cat is mandatory anywhere in the US for emissions. If you have to pass a visual inspection, I've seen people get dummy cats welded in like this -

I've seen others say they cut their stock cat in half... gut it, and then weld it around their exhaust pipe.

Why not just get a catted downpipe? It's like 1 of 2 whp difference.

That's what I was about to ask.... why not a catted one? There isn't a huge difference in power and not only will you be able to pass emissions, those of us in traffic with you will thank you.

I highly appreciate people who run catted downpipes.

I was told by vit that i will melt the cat with this set up and possibly blow motor. I can always just swap back to this dp for inspection .

Melt the cat with what setup?

 

[Flippercon]

Cte,2.95 pully, vits aftercooler

 

[Flippercon]

I have a catted rv6 right now.

If the set up you're going for requires catless wouldn't it fail inspection wether you have a catted dp or not? i.e CAI-turbo-tune?

 

[Flippercon]

No wont fail inspection for that. Just for not having a cat.

@323 has anyone told you about melting cats with the aftercooler? I know you haven't installed yours yet.

 

[Flippercon]

He said "eventually". Also others have melted them and got lucky. Im just going to drop another $300+ just for insurance

 

[W3R0]

No wont fail inspection for that. Just for not having a cat.

So youll have to install/uninstall your DP everytime you have inspection? Why buy the RV6 and not just go for a catless DP then for inspection just install OEM back on? Also arent OEM and RV6 the same 2.5" why not just gut OEM?

 

[Flippercon]

I was previously all bolt on.

 

[Flippercon]

Also rv6 is far from stock dp. It is 2.5 but less 90s and better flow vs OEM

I havent installed it yet but now i'm wondering if i've melted mine already...
I say this because the past couple of months it seems like my exhaust has gotten louder, a little raspy, and i get an exhaust smell if i have the heat on while stopped...
I thought it was just an exhaust leak but i've replaced 3 gaskets and bolts and nothing has helped.

Do you think that's a logical conclusion?
Also why i think this is a possibility is because i opted for the metal cat instead of the ceramic cat which has a lower melting point than ceramic.

In response to the OP, I've heard of people just poking a metal rod up the downpipe and breaking up the cat and taking it out to be able to pass visual inspection without having a cat.

EDIT: Not that i recommend doing that, just saying...
