Free flow front box

Post by Volksie 2.0 »

Good day i decided just to let my 2.0 9n3 polo sound nice, but not too loud to change the front exhaust box to a more free flow 1 then the original 1 claimed to be free flow what i notice were this car response was excellent in the bottom range i use to roll at 40km an hour in 2 if i put my foot down she use to excelirante quickly now its like the response up to 3000rmp is so slow and then it goes why would that be so i dont wanna touch the software on the car too make it work if thats what is needed what would you guys suggest i must do? Its the 2.0 8v bbx engine is my only solution to put the old box back? I would appreciate some good advice kind regards Anna-Mari

Put the original box back. The new one is clearly crap.
Or have the exhaust done properly in full rather than just the front box. It's probably adversely affecting back pressure in the exhaust.
