Nice one Dave.
I wish that Autodelta was here in Australia. I'd have a body kit, chip and full exhaust by now!
I went to a muffler specialist recently. He's known for getting more power through high flow systems for WRX's and Nissan 200sx's.
He laughed when he saw my Sebring Exhaust. He got a piece of metal rod, stuck it through the exhaust hole and it hit something. In other words, it was not a "straght through" exhaust.
One of his staff has a 147, they are going to design a package for the 147 PROPERLY.
Take the 147 to the Dyno, get readings, work from the back of the car forwards. He so far has designed a new straight through exhaust, he took it back to the dyno and WOW, they are stoaked. They got 10% more power JUST from a straight through exhaust/back box. Now onto the pipes and perhaps high flow cats... but in Australia it's impossible to ditch the cats, getting stricter on noise too.
