i read in a recent thread that we can pull the fuse and they will stay open at all times. Fuse 41 for 14's fuse 42 for 15 and 16's. Also i think we can change the settings for sport and track to where they stay open at all times while in those modes. FROM USER OSKEE "With the engine idling Go to settings then engine sound management and pick sport or track mode on the informant screen. Valves should open up at idle and stay open."

I used a thread here to build my own "Mild to Wild" remote switch. I think I paid about 20 bucks for parts. No soldering needed and the whole thing fits nicely in the fuse box under the hood.

With the fuse in, Sport and Track modes still go through the mufflers at idle. I think they start to open at about 2500 RPM. The only way to totally turn off the sound control is to pull 41 for a 14 or 42 for a 15/16.

If your looking at headers you have to checkout the options from TSP. Either 2" or 1 7/8" complete with exhaust plate for about a grand!!

I'm not sure there is any problem,I think the difference in the sound level is a function of the amount of throttle input!

why are ARH so much more?

I have run ARH, Kooks, and I currently have TSP on my C7 and they are supporting around 900 rwhp and I really can't tell any difference between any of them....

That's correct, you can lick the ARH headers and live. Don't lick the TSP headers.

Higgs, you need more hobby's buddy if you're licking headers

I have ARH headers and had them on my C6. Excellent quality and fit. I've never used TSP's so I can't comment on their quality or fit.

No long tube headers are legal for street use anywhere in the US. Many states don't really enforce this but CA certainly does. You will fail inspection with any LT's in CA.

Pass emissions

Obviously long tube headers, with or without cats, wouldn't pass a visual, if one were made, but would the long tube cats allow a bolt-on C7 to pass a tail pipe test? They look kind of small compared to the stock cats.

Tail pipe tests are typically used on pre OBDII cars.
