I am looking to put a new exhaust system in my AUII Falcon, What are the best headers for a Falcon?

Also will a full system including a high flow CAT affect my new car warrenty?

g'day mate, I am fitting mine tomorrow to my AUII and the whole system doesnt affect your warranty unless it is responsable for the problem.

Everyone has there own opinions on headers, but i personally dont think the big brands are always better, have alook around and ask around and check dyno sheets if possible.

cheers

Ive seen afew people mention Lukey headers here recently.

Younggun- what type of system are you putting on your AUII?

How much is it going to cost if you don't mind me asking?

Is it a 6 or an 8?

hey,

my au2 is a 6 banger. I am using advanced headers, which is a south australian company, the guy that makes them spends hours and hours on dynos making sure they perform to their best, the guy selling me them and helping me fit them sells alot of others like pacemaker, but has alot of faith in these advanced and reckons that they are the way to go... he has fitted them on monaros, heaps of SS commodores and XR's...

The extractors are mild steel because a few fitters recommended that they wouldnt use the Stainless them selves as it increases engine bay heat. They said that the mild steel extractors are one of the last things to rust out as its so hot in there that little condensation happens.

From the cat back i am going stainless steel, 2.5" piping mendral bent (which means it doesnt change thicknesses on bends in case ya didnt no). I have been told that anything over 2.5 on a 6 is an over kill. Mendral bent is definately the way to go if you can get it as the pipes arent constantly changing sizes and dont have sharp bends, this allows a smother air flow.

For the cat i am using a high flow cat made by car sound. These are the people that own magnaflow. They spend alot of time designing them so they dont have any sharp edges and have good prices.

For the muffler i am using Genie. A pretty big name. Its a pretty small muffler so it should screch! if it gets too loud i mite have to stick in another small muffler. I am thinking probably a megaflow muffler, because i have been helping to fit them on alot of cars this week, and am impressed with them compared to most.

Really though you have to do alot of talking to people, ask to see other peoples cars up on the hoist to see what sort of job they do! its not just how pretty they are! See how well they clean up there pipes on other cars before they use them, even little bits on weld and metal are restrictions and created distorted sounds.

any good, honest company should be happy to let you see other cars as they are doing them. Not just when they are finished because anyone can polish a pipe and make it look pretty, its whats inside that counts! Also make sure that you get a warranty! if its stainless it should be at least 10 years.

Take your time though and make sure you are happy that the company will do a good job.

If i have forgoten anything hear or if you wanna know anything else just ask!

good luck!

Thanks for the info mate. Up here where I live (Gold Coast) there seem to be a few good exhaust joints. I just have to find the right one.

What other mods have you done to your Falcon?

younggun · 05-31-2002, 03:53

at the momment thats it in the way of engine wise... next plans when i get a few more dollars are k & N air filter, t-series cold air intake, prehaps a uni chip and maybe crow cams, depends if im still planning on keeping the car!

Also i can get a REALLY cheap job for turbo and was seriously thinking about it, but i might wait until my warranty has expired and if i still want the car i mite look into it... other wise its probably gonna be all natural aspiration!
