Arrow muffler, Any Beetle maps?

I am looking at this  

71669PRI - SILENCER EXHAUST ARROW PRO-RACING S. STEEL MOTO GUZZI GRiSO 1200

It comes with the DB killer but no mention of a CAT.I think I saw that some got one of these but I am
a bit leery of it unless I can get a new map.

Price is $379, a bargain!


What say?

Steak uses the Mistral Hi-Pipe NodBk map in his GRiSO with Arrow, I believe. He might be able to tell you how it performs.

Thanks, got a PM to Steak right now.

Everything above is correct. No cat-con in the can, I AM running the Mistral High-pipe no dBK map and I grin from ear to ear every time I give it the berries!

Like I said in my PM response. The ARROW can is by far the best bang for the buck out there and the build quality is second to none. All parts of the ARROW exhaust system built for the GRiSO are interchangeable with the OEM parts. So pick and choose whatever suits your tastes.

Thanks Steak

Cant wait till it comes!

The description says racing but I think its really the same muffler.

By the way, the Mistral High-pipe no dBK map is excellent!
This pipe is a bit noisier than stock but its a nice raspy sound. Oddly enough it seems to only get louder up to 4,000 rims then it seems to have the same volume as the stock pipe.

or I have gone deaf..

Maybe you are in ZX12 territory

You are going faster than the sound can catch. Awesome

Who sells it for that price?

I have the Arrow, it sounds great, i had the Beetle factory map, for when i ran the stock exhaust and the map worked well on both the factory and the Arrow exhaust.
I have since, last week, installed the Beetel Hi Mistral Map No dBK as recommended above.

The bike still needs a minute to warm up, otherwise the power delivery, smoothness, and economy has greatly improved.

I can fix that.

On startup from cold, 15°C at my place, it will idle OK with an occasional hiccup.
If i ride straight away, it misses quite badly and i have to pull in the clutch and nurse it away a bit.
Literally 1-2 minutes and it will pull cleanly.

To be fair it is perfectly acceptable, but if it is possible to get rid of the stumble, that would be great.
Note: don't know if it is relevant but, altitude is sea level. Bike is garaged with a minimum of ambient of 13°C in winter.

I got mine from GRS in Perugia, Italy. The VAT tax is waved for non-EU purchasers but with international shipping it's pretty much a wash. Call or email as they have someone on staff who does speak English.

Fixed!!, thanks for the maps, will test out this weekend on an organised 800km ride

Ok, so I've done 1200+kays on the Beetle Arrow map.
My seat of the pants, observations are;
Power/torque - more power/torque over the rev range, although rarely did I get over 6500rpm.

Fuel economy - this is difficult, as the map enables you to ride quicker more easily. The fuel economy display is quite often wrong. It took me a while to work it out, but, the display must calculate economy based on throttle position, fuel delivery etc. In the twisties, my economy increases dramatically, it has been down to 5.1L/100k. on the straights, the economy drops to over 6L/100k. I think the economy meter can't keep up with the quickly changing throttle in the twisties.

Overall, i think the difference to both the stock map and the Beetle stock map is quite noticeable.
