 Does remove Catalytic help increase speed?
My friend told me remove Catalytic will gain 10hp.
when i go check with workshop, they said my car is CVT, remove Catalytic will made worst to
low end due to no back pressure.
Pls advise me
1) is remove Catalytic gain horsepower?
2) if Catalytic will made worst to low end but improve high end?
because i need to try to find way to improve low and mid end only |
