One thing I will add about the exhaust and the unique sound the alloytecs have.

1: It is not, nor will it ever sound like any earlier version of a Commodore V6, so don't waste money on an exhaust that is similar to those. EI: single 2 1/2" cat back with or without a rear resonator. (The only exception to this is one member-can't remember his name-has a CHE 2 1/2" single cat back that sounds good-in his opinion.)

2: If possible, leave the 2 resonators under the car that look like cats, these are not cats, they are resonators, and their job is to remove the raspy, fart in a tube type quality to the exhaust.

3: Bigger is not better. Keeping the stock exhaust keeps the alloytec quiet. The only exception to this (unashamed plug) is a Manta 2 1/4" twin into 3" single which is louder and deeper than stock with no drone.

Question for you impulsive, just rung Holden about the monaro cai, and he quoted me $450 which was the whole replacement for the bottom of the air intake box. So I don't know exactly what part I'm searching for. Care to shed some light?

oh n just for the record. my mechanic who told me to buy a growler tried the mace ones n got nothing from it other then a lil sound.
he dynoed his vz with the growler n got an extra 3rwkw's at higher rpm's, like 3000+.
hoping to see similar results with mine

and in regards to the 'which cats should i get' question, be aware that if u go too smaller CPSI u will throw fault codes at ur dash constantly, cause ur O2 sensors before n after the cats will have a field day with all the emmisions ur letting through.
iv been advised when i do this to my vz, to get aprox 200-300CPSI cats, as 100's will more than likely create dramas.
