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.
