Guest Brian Posted October 2, 2006 Share Posted October 2, 2006 Hello. First I shall introduce myself. I am Brian, driving a Coppa Italia here in the Netherlands. Pretty forum here and a lot of information which is usefull. Thank you for that. Now I want to buy a new crossover, I have open Gianelli pipes. Is the Mistrall crossover a good one because there are only 3 small holes which are "communicating" between left and right. There are also crossovers which are more open between left and right. I would like to have the "open" sound but no loss of power and torque. I hope to here your comments on this matter. Thanx a lot. Brian Link to comment Share on other sites More sharing options...
Guest Dru Posted October 2, 2006 Share Posted October 2, 2006 Hi Brian: I have the Stucci crossover with my stock pipes, and it makes the bike sound way more "open". I'd like to get new cans and a PC3 in the spring, to get all I can out of the bike... Where did you get the Giannellis? The website is wierd.

Guest Brian Posted October 2, 2006 Share Posted October 2, 2006 The Gianelli's where allready on the bike when I bought it. But it seems very easy to buy them here in the Netherlands or Germany. If needed I can give you adresses. Link to comment Share on other sites More sharing options...
Richard Posted October 2, 2006 Share Posted October 2, 2006 I have mistral straight-through pipes, stucchi crossover and PCIII usb. It sounds great and goes even better - it's off to the dyno this w/e, so I can give you a better idea after that as to performance. It seems the general consensus seems to be that the stucchi crossover is better than the mistral. Link to comment Share on other sites More sharing options...
DeBenGuzzi Posted October 3, 2006 Share Posted October 3, 2006 I had wanted Gianelli's but also had a lot of trouble with their site. I went for FBF, similar yet not quite as good(tad cheapa tho) I wonder what happened to the MG Ti's it came with. Link to comment Share on other sites More sharing options...

antonio carroccio Posted October 4, 2006 Share Posted October 4, 2006 To make it simple!!! Stucchi=Speed Mistral=Torque What do we need on the V11??? Speed or torque? Link to comment Share on other sites More sharing options...
mdude Posted October 4, 2006 Share Posted October 4, 2006 To make it simple!!! Stucchi=Speed Mistral=Torque What do we need on the V11??? Speed or torque? I am a torque-addict, so I've got the Mistral with the Ti-pipes. Its good, loads of torque from as low as 1800-3800, but a definite loss of vigour from 4200 upwards. it takes off again at 5000+, but the stock exhaust were actually a lot more impressive at the top end (still: standard exhaust suck massively in the midrange.) the sound is deep but muted, nearly stock at tickover but with thumping bass and a nice snarl when you give it some from 3000. its what you use most that decides, full tilt all the time or mostly midrange roll ons.

Paul Minnaert Posted October 4, 2006 Share Posted October 4, 2006 to extend confusion: there might be a difference in how it work out with the newer engine with front crossover or the old one without. The dyno results are from a bike without. Link to comment Share on other sites More sharing options...
Guest rosso mandello Posted October 6, 2006 Share Posted October 6, 2006 Sorry folks, on my Rosso Mandello (without the crosover pipe in front as on the later models) it cost me 10 HP to go Mistral x-over. I tweaked it and cut off the mid section, welded it back together with one open chamber, and now I got the power I need, 85,3 HP on the wheel. Think of that, i go for the power ciao Mogens.

luhbo Posted October 6, 2006 Share Posted October 6, 2006 .... I tweaked it and cut off the mid section, welded it back together with one open chamber, and now I got the power I need,.... You tweaked the X-over, not the front cross over, right? Do you know something about how it works without that front connector?

Guzzirider Posted October 6, 2006 Share Posted October 6, 2006 The Stucchi makes no difference to power and torque on a later bike with front crossover. It is also heavier than stock. It does look a whole lot better though. I am also interested in finding out where to buy Gianellis!! Guy Link to comment Share on other sites More sharing options...
Guest ratchethack Posted October 6, 2006 Share Posted October 6, 2006 Gents! The Manley/Lofgren dyno comparos here: http://www.visi.com/~moperfserv/more_mg.htm tell a pretty convincing story. If you read what they've done and look around the site, the Agostini/Mistral X-over results were a great disappointment on the top end. The last graph on this page is the reason I went with the Stucchi on a non-front-crossover Guzzi, my 2000 Sport. It made a noticeable difference via the seat-o-the-pants dyno in the mid-range, for the most part eliminating the stock dip in the torque curve at 4500 RPM. The Stucchi is considerably less weight than the stock box X-over. Link to comment Share on other sites More sharing options...
