sooo
f**k you hks dual drag exhaust
what a pos
put the 4 inch cat back on and a tuned length front pipe that merges into a 3 inch (so not optimal... looking for a bigger front pipe)
and boom
45rwkw in the mid range and 500rpm better boost response
more power at lest boost with better midrange
what a massive diffrence
least that solves the why it was a bit lazy onto boost questing
watch out race track
answer = shit exhuast
