no worrys pork chop
but underneath the car is a big place

immy like a 16 valve head compared to a 8 valve head 2 small valves are bigger area and better that one big valve
same goes for the exhuasts
2 2 1/2 exhuasts into a 4 inch rear box and a sperate screamer on its own works aout a far geater area than a single 3 inch and dont forget the silancer is reduced on a mongoose to under 3 inch
do the maths like on the old post we had last month
3x2 1/2 pipes
against 1 single 3 inch
