Exhaust help required
 

Hi all, wondering if you can help. I've had my 748BP for 3 weeks now and settling into riding it. I have a question about my exhaust. The guy who owned it befoe me said it had standard exhausts on. Which to me a non Duke owner looked about right. Now I have been looking about I dont think they are the right cans for the BP ? I have attached an image for you to have a look. The reason for my questino is that the mixer pipe is missing a bolt hole for the larger of the exhaust covers (The one with the sticker on covering the bolt hole !) Also the pipe have bolt holes for an exhaust cover ? Any advice welcome, also did anyone out there ever own this bike (P223 PCR).

Thanks
Paul;)

Looks genuine to me, for one thing I dont think anyone makes replacement pipework in 45mm apart from Termignoni! The guy before has put an aftermarket carbon heatshield on, the two bolts on the pipework are where the original heatshield mounts

So why does the SPS Carbon exhaust cover fit on the pipes ? Surley this cover is only meant for SPS pipes ?

If you look behind the heatguard, does it mount to a bracket that goes around the pipe? My 998 pipes have the same mounts welded onto the tubing, but I have a carbon guard that uses brackets to mount, which is a good thing because my Silmotors dont have any mounts welded on!

Found this pic on the net somewhere, they are original 45mm BP mixer pipes. Now mines a BP and doesnt have the top mounting hole ? Are my pipes the wrong ones for the bike ?

I see what you mean
 

and they do look like standard 45mm pipes. It's possible that the mono 748 had an exhaust shield with those mounting brackets in your first pic. The second pic shows the mixer with the standard Bip exhaust shield mounting.

Has the chip been changed? Can you see if the sticker has been removed on the computer under your seat?

Could it be early 748SPS pipework? Look on the cans. The DUCATI logo should be stamped on them and if they are Termi standards they will also have Termignoni stamped on their somewhere. (Termi did some standard cans on some models)

Generally the 748 has a metal heat shield. It looks to me as though your pipes are 99*, as those mountings are for what is known as an elephants trunk, ie a carbon shield that is curved. (there was one on ebay recently, dont know if its still there)

Exhaust pipework
 

I have a P reg 748 Bip and, as you say, it appears different to yours. My heat shield attaches to the mixer pipe only, as in the bottom photo you posted off the web, via two bolts.

I don't know if the type you have on are just off SPS versions or what? I think they come like this as standard now on newer models.

If yours is different, then its both the end cans and the mixer pipe that’s wrong...and maybe even the headers?

How is the bike running? I don't think you have much to worry about, as long as its running fine and everything fits OK. My only concern would be why have they been changed? Crash damage?

Anyway...take ’em off...and get some termis:P

Surely everyones heard of the fabled ducati parts bin? Mix and match seems to be popular with them, theres a few 916/996 bps with ohlins rears as standard instead of showa, wouldnt surprise me if it was simply a case of that, ie its friday afternoon and they grab whatevers at hand?

Those are not original BIP pipes. They did not have the welded on nuts for the curved heat shield. They are off an SP/SPS bike, or aftermarket pipes.

My guess is that at some time in the bikes previous history it has been fitted with a set of 996SPS silencers and end pipe work. The SPS has the carbon heatsheild that fits onto the two welded mounts. The pipework where the aftermarket heat shield is fitted looks like standard BIP.

SPS bikes arrive with two sets of exhaust pipes, the cans that appear to be fitted to your bike are the standard cans that come fitted to the bike. The second set of cans have carbon fibre outers. Both have the heat shield brackets fitted.

Maybe he had a mate with an SPS who fitted the carbon cans and gave him the old cans.

The chip that is fitted with the carbon cans is the 073 chip number, but I cant remember the number of the chip for the standard cans, i'll have a look in my spares box tonight when I get home.

oh found another pic

My 748S have the two welded nuts (I think!) on the 50mm Termignoni system that I have. This matches the SPS style carbon shield...

Thanks for he replies guys. The main point I'm aiming for is are they the correct ones for the bike. And sounds like the answer is no. It runs fine at the moment but a bit slugish from a stand still. I'll check the chip tonight and post the number. I'll also look for markings on the cans. It's going into Techmoto for an inspection on the 19th so hopefully wayne will be able to help as well.

Thanks all

They may not be the original pipes for the bike, but they certainly won't be the wrong ones for it as you can fit any pipes between the ranges.

The only thing that you will need to ensure is that the CPU (fuel chip) matches the exhaust system to ensure the optimum fueling for the size of exhausts.

TecMoto will be able to help you with this - top notch guys!

I would echo the same comments as above.

A P Reg 748BP would not have come with the curved exhaust heat shield as standard. You would have only got the smaller 'paralleogram' shaped alloy guard above the rearsets that bolts onto the lower (collector) section of the pipes.

These pipes are almost definitely off an SP/SPS version, but more importantly not off yours...

Not sure if it's relevant, but on most bikes I've seen, the cans slot internally into the collector section, whereas yours slot externally 'over the top' of the collector section.

Ditto the chip check comments, but apart from that no real problems with them

Unless you really want to change the pipes, I would just get the correct heatshield for it. It looks like you've already removed the passenger pegs. All you need now is a mono seat conversion!
