If losing low end torque is an issue, get a drop-in element, like K&N or TRD
the butterfly is mostly there for niose reduction on the GTS, plus, it chokes the motor a bit at low revs to keep it a little torqier at low revs.
I'm still thinking of going with either a short-ram Intake
or stock Intake
filter element. the Exhaust work will free up the most HP in the long run. may go CAI
, but hydrolocking is an issue out by me, maybe just use it when racing, and short-ram for daily driving.
You can always open the butterfly and cork the tube; see if you like how it performs with an open butterfly. if so, just get an Intake
. if lack of torque down low bothers you, get a drop-in element.
it's all up to the driver in the end.
