Baffle removal

Just to add you are looking at 155bhp at the rear wheel so not to bad at all!

Ok, thanks.

 

I've just managed to get out for a quick blast after waiting what seems like an eternity after doing the baffle removal mod...what can I say?...now it sounds like it should, deep and loud with no visible lack of performance or torque. I love it..
Some might say it's too loud and yes I'd guess that on a long motorway trip it would get annoying but I don't think this is the kind of bike to be doing that day in day out..plus I'd have earplugs in for that sort of travelling anyway....
When the weather gets a bit better and I'm not racing the daylight and dodging the raindrops I'll go for a proper ride and check how she performs.
Will let you know...

 

Fine looking bike you have there . Glad to hear the exhaust mod worked out. Plus I’m jealous you went for a ride.

 

Ok, this is a dyno run from a member from Triumphrat.net. I knew I saw this somewhere. I’m going to try to add two photos here, so be patient

 

Even the fueling looks pretty much spot on, and that’s with the baffles removed and restrictive discs out.

 

Are you planning on just drilling out the baffle with a hole saw or do you plan to also remove the disks?

 

Just going to remove the discs.

 

Just to avoid confusion, it's the other way round - you drill/cut out the restrictive disks with a hole saw, and remove the baffle by grinding away the exhaust tip where the baffle is welded in place

 

To remove the disc take the muffler off and use a whole saw with an extension tool from the end that the pipe goes in. It’s about 12 inches from the end. No need to remove baffles. If you want the largest hole possible use a 43mm hole saw.

 

Yes indeed - I invented that technique...back here: https://www.thetriumphforum.com/threads/baffle-removal.3813/page-5#post-201071

 

Ok, I need to find some pictures then as it seems I am confused. I definitely don't need more power, the RS has plenty, was just curious what to do for a deeper exhaust note. Sorry if I confused anyone besides myself.

 

No worries, but the info you need is in this thread - just here: https://www.thetriumphforum.com/threads/baffle-removal.3813/page-5#post-201071

You'll get a slightly deeper exhaust note if you remove the discs...and a much deeper/louder exhaust note it you remove both discs and baffles.

Always start with the discs and see how you go - there is no point (at all) in removing the baffles and leaving the discs in

 

Awesome, I just saw your previous post and was reading it. I got it now, thanks again MrTriple!

 

Just to align with SteveRS, I bought both a 41mm and 43mm cutter as I wasn't sure which to choose. The 41mm is fine (as pictured in my post) but the 43mm will take you to the very edge of the baffle tube.

Once I'd chosen the 41mm path (to be safe) it's really not possible to make the hole bigger, as it's too difficult to centre the cutter. At least that's what I found with my modest level of skill.

Shout if you have more questions

Edit: I think it needs a 42mm, but they don't make that size.

 

That’s good info, thank you for that. I was going to go the 43mm route but a safer plan might be the 41mm. The difference in the size of hole shouldn’t make any difference in sound. I should measure the diameter in the muffler just to be sure.

 

I'm sure the 43mm will be fine - I couldn't use that size because I'd already attempted to drill out the centre hole with a step drill. With no pilot hole for the hole cutter, the blade sat right on the lumpy welded edge and was very unstable. The 41mm sits just inside the weld and effectively keeps itself centred. Now you know!

The extra 2mm could make all the difference

 

Hahaha, that’s what she said . On a serious note, if the 41mm takes it to the welds I’m wondering the size the muffler is on the other side of the weld. You know what I mean. Is the pipe that the baffle slides into the same diameter? If it’s slightly smaller then the 41mm hole is ideal. But others have used a 43mm with no issues, ok now I’m just rambling .

 

Post reports of your before/after results. I'd consider doing this if it is perceptible, otherwise I'll just keep her as she is which is pretty nice indeed!
