T160 with peashooters

Now I’ve got my T160 up and running I’ve found the left black cap silencer has an annoying rattle from the loose black cap. I have a spare pair of reasonable peashooters stashed away that look like they’d fit, but the angle is wrong from the front pipes. I see that LPWilliams do a conversion pipe that isn’t cheap, are there any other options to consider?

You can get most of the different silencers fitted at one time or another to Tridents or Commandos. The problem is most are all the same internally. I put 71-72 megas on my 73 Trident. But they are just straight through perforated pipe likely with some steel wool packing. Not objectionably loud they also likely do not have much back pressure making low speed work less effective than the stock torpedoes. Same with the peashooters with the correct three punched rows of scallops which, I suppose, are correct but
way loud when you run the engine hard. So you have to keep in mind where you will be once you fit a non standard system. At one time had 3-1 system on my Trident but although they were great over 4k rpm they were decidedly not 3-4k.
Go over to the www.triplesonline.com/ page and ask them over there as well.
Edit: there is are numeral "three" before that web address, no idea how it gets there not visible when I edit it...

Could be more than the "cap" loose although the T160 and Commando black caps are not exactly the same internally?

It’s definitely the cap and baffle knocking, it can be made to do it by tapping it with a hand to the side. I’ll do a video of it.

a quick 20 second clip.

I've had every type of silencers and exhausts fitted to my Tridents for over 40 years and can categorically say that they run the best with raygun silencers, I agree that they are not everyones cup of tea. Straight through black caps are ok if a little noisy.

The peashooters on my t160 were an eBay buy ,I believe they came from armours and they are stainless with annular discharge type baffles

Well a little bit of progress as I was getting bored, again. I decided I’d simply remove the black caps and slot the secondhand peashooters from the garage to figure out what’s needed and what they sound like. It’s a bit of a Sunday-bodge of the fixings, but as the stock silencers slide on a looooong way there‘s almost enough front pipe to play with. A couple of spacers and nuts and bolts and they’re fitted. Not correctly as ideally they need a slight kink to the front pipe to silencer but as LPW want nigh on £100 delivered for a pair I may decide not to bother.

Fired up and settled to a cold tickover for me to video, and they sound lovely. Being silenced peashooters off the Commando they are not loud, but very pleasant - I think I may keep them on.

OK - I will!

just a quick vid, and I need to go and clean them now they’re filthy. Enjoy

If you tap in Exhaust Kick up pipes into UK ebay , you will find an item that might be of use to you

Have you taken it out yet?
The soundtrack is glorious on mine at around 7500 rpm without being excessively loud

Sadly no. I am waiting for the hobbits in DVLA to get their fingers out and register the darn thing. No doubt it will arrive just as I go in for my heart operation, after which I won’t be able to go for a ride for 3 months anyway.

How long have you been waiting on the DVLA so far ?, I have to register a bike and am dreading it.

Since the end of January (this year)

Provided I know before May 6th when I’ll be operated on.

It is a Triumph Triple, surely it needs a pair of Ray Guns? A bit kitsch, but nothing else like them.

Perhaps more true for a T150 for me, but I have a pair of peashooters that cost nowt and a pair of Ray guns would be £500. Easy choice

Pretty sure the Decibel copies I have are coming off. Not happy with the "fart in a bathtub" sound.

I've seen pea shooters offered for sale with the "universal fit" slotted mount. Which do you think would make the best setup? Slots? Or Norton 5/16 threaded bosses?
I can easily fab plates to suit.

I think there’s an argument to say the slotted set up is stronger as the welded bracket has more contact area. But generally I prefer the threaded bosses as they're less fiddly with no captured nuts to faff about with etc and the good ones have reinforcement in the boss area anyway.

I fitted pea shooters to mine onto the stock headers initially. IIRC the stock headers do cause the peashooters to splay out somewhat, because the stock black caps are ‘kinked’ in and the pea shooters are not. The mounting plates needed tweaking out to suit, all quite doable, especially for a habitual fiddler of your calibre.

FYI when I bought the Legend pipes, Paul needed to know if I was running stock type silencers, or pea shooters, or ray guns as he makes them to suit accordingly and each is different. My T160 pic above is with pea shooters and Legend pipes designed for pea shooters, which tucked them in, making them neater, to my eye at least. The only downside to Paul’s pipes is they cost a small fortune, and there’s nowt wrong with the stock jobs if they’re in good nick (mine got a bit scraped and twisted when I chucked it down the road).

Worth having a look around here and drop ‘em a question if needed:

Thank you.
I'll test fit today. I had eyeballed the header pipe angle relative to the muff.

I have pea shooters on my t160
But I have LP Williams down pipes
I made my own silencer mount plates
I prefer the threaded boss fitting to the slotted type
I don't use silencer clamps
