Zard and a ramair? Help?

Find it hard to believe someone would build an exhaust system that would lower the power? Seems crazy that it could be more restrictive than the standard set-up.
I have the full system which I would assume flowed better than the original headers but have no way of knowing as no tuners close to me and there doesn’t seem to be any suitable tunes in resources for an early Rocket.
Try JHS dyno , just outside of Bristol on the bath road . He specialises in Triumph tuning and is where I take mine !

Thanks Nath
Will take a look when I have the funds available , what kind of money am I looking at?

I think it's a flat rate of £200 for a custom tune ? I'm not sure if he tunes via tune ecu , I have a PCV but I can't see why he wouldn't? He knows his onions for sure ! I had to wait 2 months for my slot , he's really busy . Why your at it , he can open the secondarys , take any restrictions out and lower the running temp a tad , all seems to make the front end far lighter for some reason . :sneaky:
 
Zard Penta blue
vs
TORs red

(TORs without crossover pipe.That would have been about 10 hp more.)

@Penner Just out of curiosity, where do you think the loss comes from? Lack of back pressure and pulsing since they are so short?

When i first got my R3R, I was looking at the Penta until I saw they wouldn't fit with the ABS underneath. Even though the R3R is gone now, quite glad I couldn't buy them lol
 
As the exhaust has EU-homologation and hardly any volume to reduce noise emissions, they had to baffle it extremly.
I think, that is the main reason.
And these exhausts are not made for performance. It is all about looks and sound.
They don´t dyno them.
 
There is a pipe made by Dave Platt that looks very similar - iirc that too was a bit lacking.

Flow? - what flow?.

That’s what I had on mine when I purchased her,replaced with the full stainless Zard as I like the look and sound plus it was cheap on eBay (no way I would I pay the retail price).
Noticed DP has increased the price by £100 recently not a small increase! Mr Penner please can you recommend an available tune ecu map for my current set up please? Zard full system 3x K&N’s on a 2004 standard, many thanks in advance.
 
Sorry, no map. I just had a Roadster with this configuratoin.
The dyno graph was much better than with the Penta. But not quite as good as with stock exhaust and a good map.
So I think, that a good derestricted map could do the job and just run a little rich.
In the long run you should get it dynoed.

Ok many thanks. Just been quoted £420 to have tuned via tune ecu locally,seems a little strong seeing how it aready has a known good map installed,any thoughts?
