Hello all. I have a new 2007 victory red cobalt ss/sc (3000kms) and have to watch the pennies as I add to it. Should I add the Stage II first or the manifold & Cat Exhasut???

Thank you so much for your valued advice in advance, I love this forum and everyone has something interesting to read.

Stage 2!!

 

Stage 2 hands down will give you the most noticeable increase .

 

Stage 2 and while you are at add the dual pass end plate. Then do the exhaust and cat back as another project. Victoria Motor Products has experience doing Stage II.

 

stage 2 is quite noticeable. get it done at your dealership as they will give you warranty

 

My first modification was stage 2 and I don't regret it. The stock exhaust has a decent sound to it anyways.

 

I would do exhaust first. My idea is Let the car breath first by putting intake and full exhaust, then start giving it some steroids (stageII or III)

 

if you are concerned to change the sound more then do the exhaust. But if you want the real difference that you will feel and hear then get the stage 2. The stage 2 in our cars has the ability to throw passengers, sometimes drivers into their seats while going WOT in second gear. Best bang for buck.

 

man i want stage 2 SOOOOO bad!

 

I'm gonna have to join the majority so far and say stage 2, it was my first and haven't really felt the need to do anymore........


edit
ok except for the AirBox to hear the supercharger........

 

do stage 2 first...huge difference!

 

If you really want to get an exhaust though, crateenginedepot still has the gmpp exhausts for a reasonable price. They still have stock from the original price but when the stock is done and they go to the 08 stock, the price will be over 500, not even including the tip.

 

Im also letting the car breath first. I already did a full exaust and intake now i am working on 60s and a 2.79 Ftw! ALSO SCREW STAGE 2 !!!!!!!!! its a waste of money in my eyes (No offence to the people that did)

 

I did the CAI/Catback combo, and after engine/tranny mounts will come stage II.

 

This is what you need

If you can't afford to do the downpipe and catback at the same time there isn't any sense in just doing a cat back to help it breathe .... the stock downpipe has the biggest restriction ( crush at o2 sensor) of the whole exhaust .

Some people don't want to throw away their warranty on their new car , that was the biggest reason i went with a GM kit .
