4200 - Valved Exhaust control kit
Hello good SM people
This is one of the collective's favorite type of thread - exhaust fettling!
I would like to call on experience of upgrading a non-valved 4200 to GS back boxes with operating valves, I understand that I need to install a remote kit, some sort of pneumatic pump to control the valves. The Larini kit comes with a sensor that taps into the throttle to open the valves over 3500rpm, is that needed for the GS backboxes too? Guess it's a safety feature for the engine temps
Do not care about wiring the valves into the SPORTS button, I don't even want to know the feasibility... a simple key fob manual control will suffice
So in short do I have to buy Larini's kit or is there any more "competitive" options?
Thank you!
