as for topic... urs is a 1.3 meaning torque is
plus for normal daily use driving id say get 4-2-1 since ur gonna need the extra oomps on low-mid revs to help make up for the lack of torque.only go 4-1 if u intend to keep ur car at high revs. aka drag or track alot. 4-1s are good at high revs... low-mid revs...4-2-1 better.

midbox is just an empty metal tabung,since it has a higher volume,the exhaust gas gets slowed down..the best setup will be to keep the velocity of the exhaust gas high so it can exit the engine without restrictions and the fastest possible way..i dont understand why people say backpressure is necessary..i think the best setup will be a straight pipe from the extractor till the end but this is bloody hell loud hence the need for muffler and bullets..
backpressure is mainly attributed to auto transmission. manuals..backpressure is a nono. though i have no idea how backpressure affects autos.as for straight exhaust setup..not the best ler... best would be direct from ur extractor and straight comes out in front of ur front tire or at the side
