Can the electronically controlled exhaust valves be disabled for the continuous exhaust roar? Would it hurt anything if they are disabled?
I tried and tried in every mode but the exhaust has not changed. Is it possible this is an option for automatics only? I have a 6spd? All my Sport mode changes is the suspension/tractionWhile in Sport Mode, the active exhaust valve will remain open; verified by a Scat Pack R/T owner that used a borescope.
Just a question but would "back pressure" when the engine is cold be a reason they dont open when first starting or at low rpm's? Is the "valve" solenoid operated? If so you can just unbolt the head and zip tie it to the frame and remove the gate totally, the car would just think it is still operating as designed but will not have any effect. These are just questions as I have not had the chance to check myself,,,Couldn't you just put a new 3" cat back on & have the car loud all the time? Not try to keep the valves open?
Crazy, I bought mine from Summit, but Jegs may sell them alsoThanks Jim, exhaust leaks, and rattling panels from snare/bass have to be the most annoying sound around. Are the QTP cutouts available @ Jeggs or Summit ? I'll have to do some research for them because that is definitely on my to do list of mods for the Cat ( if it ever gets here )
Sweeeeeeet! True story! Louder the better!For what its worth the Hellcat sounds bad ass already in sport mode the cutouts are open any way if I'm not correct.
My blown water/meth 6.4 with cutouts won the dyno challenge and made a lot of people smile, as blood dripped from their ears..
Louder the better!!!!!!
Gotta tune for the cutouts being open which lead to more dyno time but it was worth it.
Nothing cooler than when you hear that exhaust snort between shifts....Nothing!!
Probably the easier way. Still want to do a controlled method priorities elsewhere for now. Car show in May I'm prepping for. Catch cans, custom exhaust dumps, lots of exterior work to complete etc. Then back to this. Not enough time. Tks for plowing forward Dave.The valves are not there for back pressure or any kind of performance. They are there for noise.. more accurately, its for a drone in the cabin at highway speeds. I am working on a valve bypass as we speak. I hope to have a test device here in a week. It will plug in where the valves plug in and zip tie out of the way. Then you can run any exhaust you want, or even put a motor on a switch to open and close the valves when you want. I still have not located the ID on the PCM yet.. so its a hardware hack for now.
