Personally I wouldn't bother mate!
Valved systems are fine where they are an OEM fit on new cars, but why waste cash trying to replicate that on an older car which sounds pretty decent from the box.
Go and speak to Infinity (the guys next to Jim) and get them to custom build a "normal" system for you. I did and I am very pleased with the result.
My old Mongoose was too intrusive at cruising speeds, so Infinity fabricated one with extra resonators at the front, which made cruising quieter from inside the car. They then used smaller silencers at the rear, so the best of the noise is out back. If I want to have a little fun and enjoy the rumble, I just open the windows.
No fancy switches to mess around with, it looks good, sounds good (without the added knob-headed attention seeking function) and only cost £600 all in.

Just swapped my old cracked bumpers for newly painted ones today.
Bit of trepidation due to long and detailed idiots guides that I've read.
However, it all went well. The rear took longer due to the boot being dismantled to get all the nuts.
One thing - after the car was bolted back together - we found a piece of moulded polystyrene that fell out of the old front bumper - we left it out.
It looked like it was shaped for a reason but couldn't work out it's usefulness so it stayed out!!
Any obs?
