Out of interest does installing just the decat with standard silencers need a remap?

No remap required

That was an interesting question. I thought the remap was due more to the cat than the silencers. Thanks for the answer, Richard.
 
Same maps for cat or no cat. Three maps regardless of cats.

Megaphone
Long or short open
Standard
 
I had a de-cat pipe made locally which is straight through each side (no cross over or H) it really accentuates the 270 deg crank beat and seems to give it better low down torque. I noticed that the stock de-cat has a cross over in it. Has anyone tried taking the cat stuff out of the stock cat pipe?
I'm thinking of doing that then I can switch between cross over and no cross over to trial the difference.
The local manufacturer is excellent and really passionate and knowledgable about bike exhausts. Check out

Harley guys drill the cats out because it creates too much heat for transmission and cooks oil at stops. I know A norton 961 who drilled it out but said it wasn’t easy.

This is why I want catless. Also, catless is cheaper to buy.

I decatted my stock X pipe a couple of years ago. It got deeper and slightly louder with maybe a slight power increase in the low to mid.
I did not remap until several months later.

My Sport has a de-catted and de-baffled stock pipes.
I had them done after the run in period .
There were 2 cats one in each pipe as they are not joined.
Now im running a power commander to control the fueling and couldn't be happier.

I bought a cat less H pipe from Frasers and "fiitted" it last night. Problem I had was that on the cat the inlet pipes are parallel larger diameter pipes that clamp over the headers. The headers can go into the pipe as far as required. On the other hand the catless H has the pipes swaged/belled out to fit over the headers and these have a depth of about 45mm. The outcome is that while I pushed the new H on as far as I could it still left the centre fixing hole about 10mm further back than the bolt.
The cat less H is significantly lighter and the silencer hangers are solid so my current plan is to leave the fixing under the engine unused, does anyone have an opinion on this solution?

Alternative is to remove the headers and take 10mm off their length with an angle grinder.

Hmm that is abit odd as I purchased Decat pipes from Fraser Ducati/Norton and they fit my 2016 Sport MKII well. They were built as you described, with the Decats fitting over the headers. The center fixing hole lined up perfectly with the bikes bolt. Sure you worked the Decats as far over the headers as possible? Maybe get a rubber mallet and tap on end of the decats (while holding the headers) to make sure?
 
I marked the pipes and I got a full 44mm into the decat, so the headers were bottomed out in the belling. I dont know enough about metal work but could one drive a mandrel into the pipes to flair them further/deeper?
 
I have the Motad catless x pipe I purchased from Norton directly last October 2016. I installed the Motad catless x pipe and short mufflers on my Commando. I also have a new SBN catless X pipe and mufflers I bought from SBN that Matt Capri installed on a bike for a customer and was instantly removed after one start up and replaced with the catted x pipe because the customer said he didn't like the smell and sound.
 
I made my own. I ordered up a few straight SS pipes with swaged ends and a couple of 22deg SS bends. I added a cross over to make an H pipe not an X pipe as such, and added a mount. Polished up nicely. Sound was better for sure. Can't say any difference in power though. I could dig out the order list is anyone is interested.

I feel foolish for asking this, but between the Thruxton R and your 961 Cafe Racer which one is the "go to" bike? I only ask because my 961 has been fairly reliable overall and if the Triumph is nearly as much fun to ride then (if it were me) it would be a pretty tough decision to make each day. I mean, reliability means a lot.

I want to know too. What’s your go to bike?

2 guys around here who have quite the selection to choose from both have the 961 as their go to. One Domi and one SF i asked both and their second choice is (crazy they both have the same bikes) ducati’s And third is Harley Davidson for one guy and an old yamaha 750 for the SF guy.

My only other bike is a 77 2-stroke which is super fun. But when ever I stop somewhere or find a really awesome bend, I wish for my 961.
 
I have a 2016 Dominator Naked and a 2016 Commando SF.
Since I received my Naked, I haven’t ridden the SF at all.
If I were to get a 3rd bike, it would probably be a BMW R nine T. My cousin just bought a new one and it’s a bad ass bike, especially when modified.
His wife said it’s comfortable on back.
It has 110 hp.
It’s shaft drive.
Air cooled. ( which I prefer)
A lot of aftermarket parts available and is cheaper than the Norton.
But with that said, in my opinion it’s components and attention to detail is lesser then the Norton’s.

I also LOVE the MM Norton tracker.
I came so close to buying one but went with the Naked instead. I’ll see what my future holds. I really need to either make my commando a 2 up or get a 2 up bike like the R nine T so my wife can ride on back.
I love the triumphs but not a fan of water cooled.
 
As I love vintage, my second bike is a Bonneville T120R which has been modified to a Café Racer, of course... Same year as I am: 1970!
And I don’t mention details on my two vintage scooters here...
But the most miles are ridden with my 961 CR!
 
Not sure whom the question was directed at but I have a 961 CR and a Thruxton 1200r. As most of my riding is a commute to the CBD the Thruxton is my normal ride, it has free spirit handlebar conversion so its a bit more sit up. If it looks like rain I take my 09 Bonnie as it is a simpler ride and more easily controlled in poor conditions.
The 961 comes out on fine days where the pleasure is the ride rather than the destination.
Just to round it off I have a 06 Thruxton with wide bars, high level exhausts, flat slide carbs, wide rear tyre and that is my hoon bike when I need to blow of some aggression, unfortunately its also a police magnet.
The Thruxton R is a very good motorcycle it would make a great engine for a Thruxton /961 Triton.
 
The 961 for the 70-80 mph cruises that involve some highway. The old Bonnie for the country roads. It wasn't made for the higher HP modern day traffic.

Hello Skiddy , May I ask if the parts fitted are from Norton (Catless X pipe ) ? The part seems to have been made out of specification. Does the hanger bracket line up with the original catted x-pipe from Norton ? This you can check when the 2 parts are laying side by side. Or if the enlarged ends are not long enough etc. If not then send it back. A 10 mm error should be quite visible. Attach a picture for Norton or Frasers to see the error.

I am afraid that now Norton are making the pipes things may have changed. I know the cats have changed in size now so you may be dealing with new versus old.
