de Catt Y power results
Discussion
As above really, I've still got my original Catted Y in place which I like for sound deadening and low emissions but I can't help but think I might be missing something and the car may posses more BHP AND TORQUE with a de cat Y such as Clive's.
I'm running an after market Ecu (Mbe) so realise I'll need a re map etc
My car mapped last year when put on the Mbe system produced around
300bhp
350 ft lb torque on Dom's rolling road.
These figures are the calculation back to the flywheel and could be as much as 5% high in reality
My question is
I'm assuming the car will generate more BHP but is there a risk I'll actually loose Torque by putting a straight through Y piece on, (less back pressure)
Has anyone got Dyno figures for a Catted to de Catted car.
I'm very happy with the power output and general running of my car but if I could remove some more heat from the engine bay and free up a few more horses as well as hold on to my torque curve Id be interested in doing it.
Am I wrong in worrying about a loss of torque with a more free flowing exhaust?

Thank you Richard 
That's one hell of an engine, I've never looked that closely.
This is the graph I've been asking for.
I'm genuinely excited at the way your engine performs,,
It seems to show the more base engine work done the more the gains will be at each other mod stage.
Your showing huge gains when you think about it,, just a bit of old Pipe????!!!!
It's a thing of utter beauty is Clive's Y and it's firmly in my sights now.
I'm so impressed with the power out put of mine using the big old heavy Catt that seeing what you've done there,,,
It's a no brainier.
You know I dream of your inlet don't you
hand made, it's just the best, it can't be doing you any harm either by the look of those figures,, 360hp,,, I'm giggling, I see what your getting at now, you often rave, as I do 
but f
k me Richard that's a beast 
I have seen your graph but somehow didn't really take in the reality of it, maybe driving mine for awhile has helped put your car into perspective. Bloody Aider mate,
Put that engine in your MG for 6 months,, outrageous.
