Hi Everyone, I've read the posts re the purported powerboosts of the system, and agree you don't get that power increase without remapping etc. However.. that aside the fabrication looks good, they look good.

Has anyone had experience of these pipes, i.e. actually used them ?

Cheers,
Ross

Ross, when your thing is rollerised I'll take you down the pub and explain why it won't work.

I have the Ipothesys system and love it. I have no ideas whether I'm getting less power out, but I get plenty for my (modest) needs. I guess I should dyno the thing just for interest sake?

Spark plugs look good and I don't get any backfire on the over run. Only other thing I've notices is that my headers don't suffer "liverspots" any more. No idea what this means, but I like it.

The sound is to die for!

I actually think that is the best looking pipe for that bike, but that is my opinion. I have it book marked and will probably order one after winter hibernation.

Question for Pete or Beetle. Has anyone done any testing with this pipe? People who have it say it works well with no mapping. What if the flow rate with the DB killers in is close to what the
stock exhaust allows through? Yes, I read all the past posts from a while ago regarding this exhaust in the "Comprehensive Exhaust Thread" but never saw anyone test it. This of course if for the slip on with bung for O2 sensor and the included DB killers that is on their current site, not the full exhaust.

Midlife - I assume you have the DBK's installed?

I've not seen any test data published. It's all been anecdotal, which means nothing in the real world. I've read absurd claims that it increases power and torque with the stock map, but with no dyno tests to back it up. Horse Feathers!

It's quite possible that the slip on works well enough with the stock map, or that the ECU can trim to its happy place without any issue. It'll do that with most pipes. Even the full exhaust probably does.

More power without map modification? I fart in their general direction.

Wac - yes I run it with the dB killers in. I've never tried with them out, I suspect they would be too loud for leafy middle England!

I have heard from enough that it runs well with stock map. I wish it was not so expensive to ship from the States to Australia, or I would send it out to you to play with first. I doubt it will run well without the DBK and stock map. I still love the looks of it.

Buy a wideband controller and sensor and log it yourself. I'll happily build a map.

I admit that I got an Italian friend to act for me in buying the system, but he said that they were very straightforward to deal with. It had to be made to order at that time, but I don't remember having to wait very long.

2 into 1 into 2 is a shame exhaust note-wise... The spine frame V11 Sport variants still have the most loin stirring exhaust note of all the modern Guzzis. The pulses stay separated and deep as it is a true 2 into 2 design, albeit with a crossover.

If someone could come up with a reasonably priced 2 into 2 system for the GRiSO, I'd be all over it.

I have a plan to build a 2 into 2 with an X pipe instead of the conventional cross over. Any thoughts on how far from the exhaust ports for the X cross , and total length ?  This is being done to try and improve the Wet Fart noise I get from the current pipe on the track bike

Now theres both a can of worms and somethin I thought about. If you made your practice pipes in mild and the finished in staino , or Ti,youd save a heap. If you put the X under the sump it would only be a matter of trial /error ,cut/shut to move front to back. Because its a track bike (aesthetics not important),you could have the right side come inside the footpeg and over the swingarm. You could put a similar bend in the left side but go along the bike,if you get my drift. Then you could have 2 high mounted mufflers.
And theres the blower.....

For anyone young enough to remember, best exhaust routing already covered by Paul Sample albeit for parallel twin !....[You must be registered and logged in to see this link.]

Granted I am a dumdum, but I'm not seeing where you need to relocate the Oil Cooler? [You must be registered and logged in to see this link.] I imagine fabricating the dual tracks of this system to the twin cans would be possible, but then you'd only have the lamda on one cyls.

I really like that system, but found this locally on Craigslist for a great price. Installed and really like the sound and look. [You must be registered and logged in to see this link.]
