I could be wrong But im i right in thinking the 136bhp M47 doesn't have swirl flap's ?? and thats a gr8 result im busting to get mine done tho cant find anyone here in belfast . if anyone out there knows anyone in NI pls let me no .
Decat downpipe will help the turbo spool up slighty earlier & more freely, i did mine after a remap & now the car is very rev happy :-) Plus it should improve the mpg aswell if u can keep that heavy right foot at bay!
