Hello,
I have been running the E valve Vandemon Titanium Exhaust on my 2020 Rocket R (Red) with 8200 miles.
With Penner tune, for 8 months.
I mounted the push button switch on the left side right in front of the oil filler cap on an intake manifold bolt.
(I replaced the plastic push button with a stainless Momentary push button)
Now about how it sounds, in stealth mode it is as quite as the stock exhaust but less back pressure without the catalytic converter. There is a noticeable increase in performance, over stock. This could be contributed to half the weight.
Also installed,
Free flow air filter
New plugs
Now in performance mode, the note is throaty, deep, and the engine “Revs” much quicker to red line, and pulls hard……
But what I have noticed most is how smooth the engine runs now. There is an increase in HP & Torque, the traction control indicator flashes a lot now. With traction control off, I get a lot of wheel spin.
On the highway, it’s nice to reach down and switch to stealth mode and run quiet on long runs.
My gas mileage has gone up by 5 miles per gallon, on the highway.
The best of both worlds.
Not cheap, I got a deal on Black Friday at $2600 plus free shipping. Couldn’t pass it up.
