Extractors with stock exhaust?

[Troy711]

I'm thinking of whacking a set of Pacemakers on the Stato. Would I see much improvement if I retain the stock exhaust? Only reason I would keep the exhaust standard is because I don't want it hecticly loud.

Just get the exhaust to flow good with minimal extra sound,it can be done.The Statesman has non stock exhaust with high flow cats and is not too loud.Its built for more power not more noise.Any GOOD exhaust place will be able to help you out.

Actually.. I heard this:

YouTube - Holden Commodore SV6 2.5 inch Exhaust

And it sounds pretty good (for a 6).

If you don't want it loud but want a decent flow why not buy a second hand HSV cat back.
They are on eBay all the time, $100-250, definately worth the money and they are full stainless steel.
You'll just need to adjust the length if you buy a normal sedan system.
I have seen grange systems on there before.
A lot of super6 guys do this, nice note and still get decent hp figures.

Putting extractors on and keeping the stock system will give you better economy and better low to mid torque. But use Tri Y's. If you put tuned length on, all you will do is create more back pressure as the extractors will get the exhaust moving faster but the stock system will choke it back.

This is what I was looking at

NAAF: Wanna do me a deal on a set

That set is bloody cheap....but I can do you a one off for $400 even....normally $420. Postage, according to the Auspost calculator would be approx $40, or if you are going to Sydney you could pick them up.....

 

[Troy711]

Would a cat-back set up do much? Or would it just be for a louder note?

 

[Not_An_Abba_Fan]

It would make a small difference, but the cost wouldn't justify it. There isn't much available for the WM V6, on the V8 it would make more of a difference. I would leave it unless you wanted to spend another grand for not much improvement.

I should just save my pennies for a decent S/C kit. I've just gotta work out how to write it off on tax lol
