Advance Headers

Exhaust Technology are pritty pricey (compared to some), But the quality of work that Mark produces is excellent. They use top quality products and they KNOW THEIR SH*T!!!!

A lot of S.A high performance street and race cars use them!

Anybody seen these? Made by Advance headers in adelaide. Cheap enough... Web site claims a 17 rwkw gain...

The guys at Kirrawee Mufflers recommend the Advance headers. They have had some great results and the prices are very good.

Getting my exhaust done by them on Monday, so I will let you know my opinion after it is done.

Cheers.

The split dump pipe design is good, however you will more then likely find that a 3.5" dump (single) will do the job better.

I actually went from a 3" split pipe (with a 1.7" wastegate pipe) to a 4" pipe and gained 20rwkw off the bat.

Furthermore, in my opinion the design of that dump pipe will not be that effective. To have effective gas flow, you would want to gradually introduce the gasses back into the system.....ie, the split pipe should come in at an angle rather then on the side.

My 2cents worth

Advance dump with high flow cat fitted up now, I am very happy with the sound and performance difference. Running twin 2 1/2" from the cat back.

Just waiting for the car to be edited now as I have had an overboost issue twice so far. Boost is definitely up. Feels much stronger down low.

Cheers,
