There is a small pipe at the front of the air box about 50 x 200 mm, and it is piped to the front of the car, where the fog light on the right side used to be.
The exhaust is a 3 inch pipe from the cat conv and the actual muffler is about 4 inch and the tip is 5 inch. Is that too big? It sounds good especially when I drive the car hard.
Any help or comments would be appreciated.
Thanks

Unfortunately, you can't squeeze blood from a stone. A more free-flowing exhaust will be louder, but perform better. A quieter exhaust will be more restrictive and perform worse.

Regarding the intake, you may have affected the n/a tuning by replacing the oem air box with an aftermarket air filter. To correct this, you may need to add an air-fuel meter (eg. A'PEXi S-AFC), and spend some time on the dyno re-tuning in order to restore the performance (in fact, you may be able to get it even better than before).
