I have a mid pipe comming from PJ. It appears you do not hook the O2 sensors back up to the pipe. How does this impact the fueling with no ECU change. Any information or direction to links will help as my search has come up empty.
I would think that you'll get an error if you don't connect the O2 sensors without an ECU update. They're a monitored part of the overall engine system and, if they fail with the stock exhaust, you get an error. Also, with no feedback from the O2 sensors, the ECU would revert to a base map for the fuel injection. I would for sure check this out before I went to the trouble of replacing the mid pipe.
The 02 sensors stay on the standard part of the header pipe which stays attached on the cylinder.
The Mivv pipe only attaches to the standard headers approx 200mm/7" down from the engine.
You have nothing to worry about.
You're most likely going to want something with a db killer. MIVV makes some really nice looking cans that will bolt onto the MIVV decat. There is a user on this forum working on a db killer for the stock cans as well.
I already have the termi slip on so I am going to try it with that on as it is a direct replacement for the stock muffler. May have it on this afternoon but will let you all know the results soon,
Got the system on today. I rode home, 25kms/20 miles, with the db killer out.
Yes, it is pretty loud and you do loose a bit of bottom end.
I put the db killer back in and went for a shorter ride and that almost bought the bottom end back as it was before the change of the system.
I'm getting a Dyno next week so all should be sorted then.
I'm going for a 400km/300mile ride on Sunday, so it'll be intersting to see how things go on a faster ride.
It is nice not having that extra 6 kg hanging off the under side of the bike.
So far, I'm happy with the result, and my bike finally sounds a bit more like a Ducati.
Thanks for the update Peter. How did the install go? What db killer are you running? Compared to stock, how is the sound with the db killer installed? I am anxious to get mine mounted up.
The install couldn't have been easier. I took it to my Ducati mechanic and he had the whole thing done in 45 minutes.
It beats getting the shits working off the garage floor.
I didn't know there was more than the db killer that came with the pipe.
I cut the db killer down to within 12mm/1/2" from the end and tried that.
Bloody aweful, it was pretty loud and bit tinny for some weird reason. So I installed another db killer, I have another Mivv muffler, which is the stock length and it sounded great. A bit too quiet when idling, but blip the throttle and the low down rumble returns, fantastic.
I'll weld the cut down db killer back together, then cut 12mm/1/2' from the open end off so I'll get a bit more sound out of it.
You'll love your pipe, don't worry about that, your neighbours mightn't, but stiff shit!
There has been some question about the MiVV decat being the same for the standard pipe vs. the decat supplied with a MiVV slip-on. The only difference between the two is the "link pipe" supplied with the decat for the standard exhaust. MiVV customer service has confirmed this.
so, in summation, will the MIVV mid-pipe fit onto the oem muffler without further modification to it or the ecu? if so, this is the exact modification that i'm after.
Great site PJ! Its great to see the whole package AND with the side cases too.
Can I ask if there is much weight difference between all the mivv slipons ?
cheers,
wit c
So as of right now its an either or situation? I buy a cat delete and keep my stock pipes wich means later on I wont be able to get a different exhaust or buy the cat delete that makes it so I need a new exhaust? Is that correct?
I'm considering this very MIVV mod, but going into a custom mounted set of the streetfighter stacked carbon cans. I think the mounting plate and the splitter pipe (for the 1-2 connection) is all I will need. Keeping my fingers crossed.
that just might be what the doctor ordered; lose the looks and weight of the cat while being able to use either the stock muffler or Termignoni slip-on (i personally am not a huge fan of the large Ti can). have the ecu reflashed if necessary? and off you go.
I'd hate to upset my perfectly running stock set up that I have.
I'd love to improve the sound of my stock OEM tips.
