hey folks just wanted to ask... I'm planning on exchanging my Hurricane open-pod air filter with a drop-in K&N air filter. My car also currently has original exhaust piping but I might wanna change it to straight piping. So my question is, is changing the open-pod for the drop-in a good idea??? and is RM220 a reasonable price for the K&N air filter??? Also how much does it cost to install straight-piping on my car (Kelisa) and how long does it usually take to install it??? Thanks in advance for the help and info...
