Ducati Monster Forum

I have a 2007 S4R T.   I'm buying an exhaust system next week, and I'm confused about the best way for me to go.   Are you guys aware of a difference between the Full system DP ECU and the Slip on DP ECU?   I was considering buying a slip on system, and going back later and buying the mid-pipe and header.  But one of the dealerships I spoke with said that the DP ECU is  different in both systems though it would compensate for the header and mid-pipe.  Another dealership told me not to buy the slip on, that if I couldn't afford the full system to save my money and not bother with it tell I could afford it. 

I don't have a lot of money to play with here.   my best price on a slip on system is 1732 and 150 install.   My best price on a full system is 2900 installed.  it would be tight, but I could manage the slip on price.  I can't afford the full system for probably another six months, if then. 

Opinions please.  if you guys know of a better prices on either kit let me know. 

I'm pretty sure there isn't a "slip on" or a "full system" version. As far as I'm aware, there's just one version of the dp ecu for each bike. 

My bike is the S2R800, but what my dealer told me was that the DP ECU will have a range wide enough to cover a cat-less midpipe. It certainly does.
If this means there are one or two versions of the ECU or if any of this applies to your bike, is beyond me.

They should be able to give you a straight answer about the ECU - different or not.

I've got an '07 S4R w/slip-ons and DP ECU. According to the dealer. Slip-on vs Full system ECUs are different.  Both have axed the O2 sensor and have similar fueling maps.  However the Full ECU has slightly different ignition map.  According to them they are functionally interchangeable between exhausts with nominal differences in power and dyno maps.  E.g. mating a slip-on ECU with a full exhaust you wont achieve the full exhaust performance.  I got the impression you'd be leaving 10-15% of full system performance on the table.  I can tell you the performance of the slip-on ECU is outrageous.  The only reason I'd concider a full system is the appearance.  I'm growing to hate the udder.

The 45 mm stock pipes and bypass don't yield the power the 50 mm full system does.

It's a three part story. Open air box without the big pipes or ECU doesn't work, pipes without open airbox or ECU doesn't work - it takes all three.

Open airbox for more air in, 50 mm pipes for better flow and more air out and ECU for more fuel.  All three, the full kit will yield from 10 to 14 HP increase and 10 lb.ft. torque.  And db killers out give a extra big increase of low speed torque from 3500 to 5500 rpm.

The slipon, bypass header with proper ECU will yield less than 1/2 the increase of the full 50mm kit and ECU's are different for the different kits.  The slipon ECU is much less rich because of the considerable restriction of the catalytic udder with remains with the slip on kit.

The link below is an excellent narrative and has power curves for the full kit. Notice the big increase of torque at low rpm with the db killers out.  Good reading if you haven't seen it before.  Thanks, Brad Black.

If  you look around you can find used 50mm cans and pipes relatively cheaply and you can re-flash your OEM ECU with MonsterMash or one of our board sponsors, sorry I forgot which one.  Reflash for less than 1/2 price of the DP ECU when bought separately ($1200).

LOL...I've even PM'd you with those above notes, but apparetly you don't believe me.  Unfortunatly, the DP and full termi exhaust sold 2 days ago, and went for $1700 shipped, including the virgin ecu.  [drink]
