Quat-raceECU-PCIII

Would a system like the Quat-D not lose bottom end torque/ horsepower being little more than 2 headpipes and a silencer box?

My experience is that I gained bottom end(but not measured), mid range (measured) and lost from 5000 rpm on up(measured).

But I was not measuring against my own bike, just another stock guzzi.

I think it is a greater engineering challenge to get power out of short package, but possible, with a well tuned and dampened labyrinth.

Certainly, the result was a compromise and not a total loss.

On stretches that I would hit 130mph with stock mufflers, I was hitting 125mph.

Not a huge difference.

The Quat-D does have other advantages.

1) If you drop your bike, the expensive muffler is not the first thing to go.

2) Saddle bags can be mounted lower, so the bike handles better.

3) Center of gravity is lowered and more forward, so the bike handles better.

4) Doubles as a leaf blower

Another point is that although it cost more than most slip-ons, it costs less than most slip-ons and a Stucchi cross-over.

But yah, I too would like to see more peak power out of it.

Sorry to hear that the race version is just a hollow box.

You might be better off taking a Stucchi crossover, adding a couple of restrictors and praying you don't get hit with a noise citation.

"Funny thing, I haven't met someone with a Guzzi that didn't have plans for it.

 

I know I do. as most of you also know because I constantly ask stupid questions."

 

Always thought that it was only the stupid who didnt ask any questions...
