David PLatt (OUTLAW EXHAUST)?

[Allan S]

I installed the Dave Platt Roadster Performance Silencers from the UK along with the CAT By Pass from Motorcycle Exhaust Professionals from Australia (Dave Platt did not have a By Pass available at the time). Both were installed by my Triumph dealer. Dave Platt also mentioned to me that a remap wasn't needed however I opted for the Triumph Aftermarket Exhaust System remap from the dealer (Apparently there is only 1 remap available). This setup is also quite loud but not obnoxious at idle (mostly due to the CAT By Pass) although probably not as loud as the Outlaws. Can't wait for Spring to arrive and the snow to melt to start riding.

Need a little help from anyone out there. I purchased the David Platt Outlaw exhaust on Ebay,with cat bypass, last week. I was going to install it myself but I just bought a new set of Avon Cobra's I need mounted and balanced. So I asked a well respected mechanic who specializes in Triumph, BSA, Norton but works on all bikes. In fact he owns a Triumph Rocket Roadster. He told me basically that buying these pipes was probably a mistake because if not buying from a big name brand(Jardine ect., )power commander,tuneboy,ect will not have a tune for this set-up and if you also wanted to eliminate the stock airbox for a K+N or RamAIR there would not be a tune either. I said to him if I just go with the new pipes with cat bypass doen't the ECU do the 12 minute remap and he stated he wasn't so sure if this would be sufficient. I went on the power commander web site and for the pcv didn't have a map for the pipes I bought. He further stated that if you can't properly remap, especially if also do the stock air box elimination with the K+N or RamAir you could be headed for problems running the bike to lean or rich. So does anyone know if 1) I only do the pipes with cat bypass does the ECU remap it or is he right that it isn't really going to do what you need, or 2) if I go with the pipes with cat bypass and either K+N's or a RamAir set-up how does one get a remap if there isn't a standard map for this set-up? Any help would be appreciated.

I changed the mufflers for Daves and left the collector box in place. Its not a CAT but it is a bit restrictive. The cats were in the mufflers on my roadster. I did the 12 minute thing and come spring ran the bike for a few 100 KM. It ran great, a slight bit of decel pop sometimes so when I passed the dealer recently I had them remap with the Tors map. Bike did run and idle a little better. I would be interested to meet up with Faraday in Caledon to see what difference removal of the collector box makes. I spoke to a well known dyno tuner here in Toronto and he said the only proper way to get the max from your bike is to dyno it over a few hours and do a custom tune. I am installing Ramairs and will definitely do that when I do as the standard triumph tune wont accommodate that.

No problem meeting in Caledon. Let's wait for a fair weather Sunday.

Adding a link bike changes the sound of the bike from a Spitfire to a Lancaster.

@Allan S did you get a price on the dyno tune? There is a dyno shop near London as well. I don't know anything about them but if the price is right I would do it once I get pipes.

Just bear in mind that most dyno tuners will only tune via a power commander as that is the system they are generally trained on . That said , they will go into the bikes ECU and alter settings such as gear restrictions , rev limit increases , secondaries and temp .
You will have to do some research to find one who will actually remap the ecu itself and this can often be expensive ! Good luck and when you find one , post up the results and name and address of tuner !

What parameters can the PCV change on the Rocket? For example, I heard that the PCV states that you can map each individual cylinder, but someone told me that is only on a V-twin motor?

Dukes of Cycle in Toronto have a good reputation. I spoke to Carmine the owner and he is confident with Rockets. I am waiting for more normal temperatures than the 1-5 degrees we have been getting. Apparently that makes a big difference too? He quoted "around" $800 CAD as he said it was a good few hours work - inc balancing throttle bodies ( If I remember that correctly)

I think mine sounds like a Cesna at V1

WHY did you choose PLATTS exhaust and what is the price ?

I liked the look of two exhausts and the shape of his model. It doesn't have any joins or screws sticking out, its slightly shorter and much lighter than the stock but retains the look of the rear end. They are polished stainless rather than chrome. They sound awesome. I think I paid about $800 USD incl. shipping from UK to Canada.
