Electric Cutouts?
 

I have a 2010 Chevy Silverado LTZ. I haven't done anything to it except put on a Cherry Bomb Extreme muffler. I still have stock cats, engine, etc.

It's got a good tone but it's not loud enough. I heard from a friend that if I install electric cutouts right after the engine but before the cats I can get a beast sound. What do you guys think about this move?

I'm in Texas so the E-cutouts are a bonus since when I do inspections i can close it, and when I'm on long drives and don't want it giving me a headache I can also close it.

How expensive is it? I saw some electric cutouts from DMH that look affordable. I'm not sure but I think I only have 1 cat, so maybe I can get away with just 1 electric cutout instead of duals.

I haven't found any shops in North Dallas that will do this kind of work, so if anyone has suggestions here let me know. Also if DMH isn't a good brand please suggest an alternative.

You won't find a shop that will do that type of work generally because it's illegal and can involve huge fines or even losing the business. Mounting it where you're talking about will make it obnoxiously loud but will effect performance in a negative way and trigger engine codes. If you want a good healthy sound rather than loud and crappy, invest in a good exhaust system and headers. With the right setup you'll get a great sound and improved performance.

im not a big fan of the E-cut outs i put one on my last truck and about every 4 months the motor went out

That seems suspect. how could that cause engine problems?

I think he was talking about the electric motor on the cutouts.

oh ok that is a little less scary :P

Well what brand of E cutout did he get? I'll know to avoid that brand.

It can cause ambient air temps to cool the heads off too quick, this will cause them to warp as well as heat. The cut outs are cheap($30 a piece, u need 2), the electric remotes are $150. Dont get em, not worth it. Get some long tube headers with ORY-pipe and you will gain more torque and better screamin sound at WOT. I got mine for $300 shipped 3 days to the door. They are direct bolt on.

What is WOT?

Also keep in mind that I'm in Texas and need my cats to pass state inspections. That is why I liked the idea of cutouts so much because I can toggle my cats on & off as I please. If I don't want the loud noise on long drives, or if I need my cats on for state inspections.

Like Ruff said, go with headers and a high flow cat. An old trick I learned was to loosen the flange bolts at the dragstrip and uncork the headers when I raced. Full flow for hp on the dragstrip and quieter for the street and legal.

He said an offroad Y pipe, not high flow cats, right?

That headers + high flow cats is something a friend got and it was over $2k installed. That's way more expensive...

Check prices man. Ruffneck mentioned that he only had a few hundred in his setup

This is the sound I want:

I don't know if I can get that on my 2010 Silverado. Apparently he has high flow cats + no muffler + y pipes. No mention of headers that I can see.

Even if price isn't an issue, finding a shop in Dallas that will do this work will be hard. I need some suggestions from people in the area, haven't found any myself that will do it. The ones I called said they won't do any cat work due to laws and/or fines involved for them.

Order a premade kit and you can do the work yourself. It's not difficult. You won't find an exhaust shop that will take the chance of a 10000 fine or lose their business license because you want the cats left out. It's a federal law and too much liability.

Can you link me to one so I know what I'm looking for? Thanks man.

Your vortec motor is gonna sounds way better than that. The ORY is very easy to install or take down. So you could use your stock cats for the inspection and then swap it out with the ORY. The long tube headers with the ORY all cost me $303. Took me about 2 hours to install myself. I can try to post up a video of mine but it is cammed with a big lift so the tone of the exhaust sounds way different than stock. And remember, just cause its loud dont mean its faster. I have seen and read about so many guys making their trucks louder and then complain how sluggish it runs. All I am saying is do it right so you don't have any regrets. I will be glad to answer more questions to the best of my knowledge. :)

I really have no idea where the ory connects, much less how to put it together myself. I need a visual of what the whole system will look like in both configurations. Can you explain? Thanks.

There is a flange behind the cats and in front where it connects to the manifolds. Here is a pic of my headers before installation...

This is real similar how mine sounds...

Everything is straight up bolt on. Even if you only got the ORY it will bolt up.

Is the part on the left the ory pipe? So it just bolts on to the headers? Does it bolt onto the stock headers like that too? What connects onto the other end of the ory pipe?

And what goes on the other end? The cats? I thought the cats were welded on.

Bolt on, everything is bolt on I say again.

Ok. I just wanted to make sure. I'll get under my truck and map everything out. When you installed your setup, did you use a lift? All I have is a jack

Yeah just jacked up a little. Soak them bolts with spray lubricant for a few days. Taking off the factory stuff is the hard part. Everything else is cake. Remember disconnect ur battery! Passenger side headers are real close to the + cable so gettin them in there you have a chance of arcing it, like I did.

I wasn't planning on headers but I guess I should?

Up to you.
