155/156 extrator swap with 147. Any difference?

Sifu's,

155/156 extrator manifold swap with 147 extractor manifold, does it make any difference? Besides not having any CAT, will that factor give it more peformance?

Bro, the 147 extractor are slightly smaller in diameter compared to the 156. Performance on the higher revs might be affected but I'm no sifu... But I've tried the opposite instead which later became a custom pipe setup instead of bothC

Ic, so what is your car set-up? would like to know, what extractor are you using?

I'm on a custom setup... from extractor all the way to the rear. Rear box is Novitec... Custom job by TorqueGear at Sunway
