told u buy tc u went for exzos pula. long or short extractor and why two muffler

long 4-1 or short 4-1. u need to play afr also
enjin use 3 main ingredient to produce power. air (oxygen) +fuel +spark = fire.
tc open throttle increase air, KNN filter is fake K&N ? also increase air.

u still lack of fuel n fire. how to settles this two

i rasa no enough space for it.
there is no pipe length tuning before joint intersection. so i think no diff to use 4-1, 4-2-1, 4-3-1

i dunno man. original is K&N not KNN <<<< sure fake filter ady

not sure what u r setting tc mode will improve fuel or spark meh?
just air no fuel no spark where got power one

u oso feel suspicious he say like that.
same as taking money from left pocket put right pocket
then urself feel good very much becos richer now

he affordable dun worry man
