VY auto v6 - help

[paynetrainvy]

I am some what of a novice when it comes to engine mods. I know the very basics about the motor. From doing a bit of reading through this forum I have gathered that the best mods for my car would be a

69mm Throttle body
25mm manifold spacer
12mm plenum spacer
CAI
And 1.9.1 roller rockers - with new push rod????

Is that right ?? It's a stock vy engine. Is it worth doing these mods with a stock exhaust ???
Sorry for all the questions it's something I'd like to do I just wanna make sure what I'm doing is A. Right B. In the correct order C. Not going to waste money cause I should have done my headers or exhaust instead.


Any help would be awesome

Your list looks the goods mate,id retain the stock throttlebody at the moment and get a good catback exhaust.A mandrel bent 2 1/2" will be plenty.Keep middle and rear resonator whatever you do or it will sound like a fartinacan,not cool.

Give your Airflow meter a clean aswell with CRC Contact Cleaner and make sure your car is in good allround running condition before starting mods though.If you have the money then get the headers and catback installed at the same time.

Exhaust
Rockers
CAI
Manifold spacer
Plenum spacer

Yea I've been looking at either a 2 1/2 cat back setup I just dont want it to drone. It's a v6 I know that an I'm not pretending to have a v8 so what system do you think would suit that all I want is a nice note when you give it a boot full but quiet when I'm driving normally. Sorry about all the questions as I said I don't want to make the mistake of getting the wrong thing cause I'm under informed.

Unless you're planning on putting a large cam or supercharging your setup, I wouldn't worry about headers, money definitely could be better spend elsewhere.

As for an exhaust system you can use a redback system, or ideally a ex HSV unit.

Hope this helps

Redback - catback 2 1/2 - dual dump tips $450 installed

REDBACK 2.5" CAT BACK EXHAUST VT VX VY V6 COMMODORE (eBay item 360310597299 end time 25-Dec-10 19:00:14 AEDST) : Cars, Bikes, Boats

$165 or +$40 for delivery

Its 2 bolts and a clamp, could be done in 30 mins with 2 people or about a hour alone. Easy with hoist or ramps but still easy with jack and stands.

Save some money and do it yourself.

never having played with an exhaust, is it easy enough to attach different tips on these exhausts????

and that system wont fit my car as its a series 2
