Collector link pipe Mod

Gents as promised an update

just too let all you guys know i have had the first exhaust modified...i only picked it up last night and handed it stright to a forum member to fit and test so no pictures yet.

as soon as i have some news i'll get back to you all... please note this is for 01-03 pipes only at the moment..the early type are a different design

price for pipe mod will be £65 + £40 surcharge on your pipes...this way it spurs you on too get the modified pipe fitted quicker and return your pipe to me(for the refund of the surcharge) ..this way your bike is off the road for the minimum amount of time .your looking at an hours work to complete both sidepanels off and belly pan ,panel between the rads,rear can and link pipe off, undo front header bolts..no need to loosen the rads(well i didnt)..this should then allow you to remove the collector pipe..then assemble in reverse order..remembering to apply some exhaust paste to the front header pipe where it bolts back to the head.

Very interested in mod for a 2000 mille, let us know when you've sorted it please? :thumbup

Hi Deej...is it a 2000 mille or an an 01-03 model on a 2000 plate?..need to ask as the exhaust are different and at the moment only doing the 01-03 pipes.

i'll post some pics in a little while to show you the difference

Are they.......? In what way are the headers different redratbike? :dunno

Gents check out the pics top one is 98-00 bottom 01-03...not sure if you can modify the early pipe or how...if anyone knows any different please let me know ..i've posted a this question on the af1 aprilia forum as well

:thumbup Now I get you squire, as in the shape slightly altered. They are still fully interchangeable between years.

The mod is the additional tubing from the curved rear section to the straight centre link section, and certainly MHP will do it to either set up. A slightly different curved additional from one set to the other I would of thought? Good to hear you are getting all of this on the roll redrat, excellent stuff

any pics of the modified collector?
thanks

:nana sorry mate couldn't resist!! if you google mhp collector mod you'll get a hit I'm sure.

Deacs :thumbup

ps ........... I like your sig :thumbup

I wouldn't think that you would get much improvement with the early collector been the rear & front pipes join so close together & would be balancing themselves pretty well as it is , the other thing to watch is the location of the link pipe to the side of the Oil tank & hoses as things get bloody hot & heating these things up more than just engine temp may course problems .

Anyone know why Aprilia changed the exhaust design :dunno

I believe it was when they went for the bigger valve heads they changed the collector shape .

ah ha, thanks deacs, i wasn't really paying attention was i?
i've been away and borrow a friends laptop for a few mins so speed read the posts, doh.

a good link on AF1 about this mod has been updated with some dyno graphs and makes good viewing and some mod pics later on in the posts

http://www.apriliaforum.com/forums/showthread.php?t=138578&page=9

the kevlar covering for the oil pipe looks like a good idea, just to be safe

hope to get some pics soon...i passed it straight to someone before pics were taken

ok gents.as promised .heres the pic of my first modded collector..it has just been fitted and hopefully will be given a test ride at the weekend...weather pending:thumbup

i should have another 2 modded by next week so anyone interested let me know...

below is a pic of early 98-00 and 01-03 collectors for comparision...i cant see anyway to mod the early pipe in the same way

looks good, well done
i am still interested, would the modified pipes be cleaned like the one in the pics?
since i'm not that far away is there any chance of riding up and fitting it at yours so i could just leave my pipe there or would it be best if i took it home to fit?

looking forward to your weekend review
hope that 5k dip disappears

Side by side the early system looks better, theyve already kinda got this mod built in. I wonder if Aprilia changed them for a good reason like performance or if it is like the early/late air collector thing.
