Exhaust Mod

Were the power gains noticeable from the cat?

If you put on a supper high flow cat you will get a 10kw gain at the wheels top end

or de-cat pipe not that I would do anything like that

bashed cat! you've got the stealth ordinary look of a normal legal cat with the performance of a decat pipe

Does give a sh*tty tinny noise at high rpm thou...

I have 2 hotdogs though, 15" and 13", is that going to at least dampen that tinnyness?

Wouldnt recommend a punched stock cat.

I tried that with my exhaust and its sounds realllllll harsh and (*bad*).

Pulls harder though.

Ok so got a quote from liverpool exhaust today for my last exhaust mod:

Hurricane Headers:
Installed - $1400
By itself - $1000 still

both those with HPC

Do those prices look right ? I refuse to pay $400 for labour!
Would someone be so kind as to help me out installing the headers? 1000 for the HPC'd headers seem expensive, i thought they were about 800...

[bushido]

no those prices seem about right
3 years ago i paid $1600 installed, HPC coated and a high flo cat

[Gholdwayne]

i guess i'll have to live with that. lol.

i'll just buy the headers with HPC and probably get help installing it sometime, maybe in DIY day.

[I8A4RE]

No thats a rip.

Dont know why your worring about HPC coating though. I dont have that I got a turbo and have 0 heat problems

[Gholdwayne]

but isnt hpc also to protect the headers from corrosion? i guess it would be better if i do the coating myself

[I8A4RE]

If they wear out while you still own the car I'll but you a new set lol

[Gholdwayne]

sounds good! you do realize im keeping the car until it is not sensible to repair anymore right ?




bah, but you're not serious, so....

[Bennoz]

Haha, yeah HPC is a toss unless you're making serious power.

[Gholdwayne]

^^ yeah i knew that, but not only that, i know that hpc is a heat resistant protective coating, therefore im not too concerned about the performance benefits that i'll be missing out on, but more on the protection it provides.

[Bennoz]

but more on the protection it provides.

As in corrosion? It won't happen. Only thing its good for is aesthetics.

[Gholdwayne]

olly's extractors has some rust spots, which i don't understand, as im pretty sure they are coated. bah, if it is completely useless for my application, then i might consider getting them without the hpc.

[Bennoz]

Its surface rust! Just sand it off & hit them with some heat proof paint - available in spray cans from any auto shop.

[Gholdwayne]

I remember you were selling rpw headers before and they were rusty as chips! but then again they looked like stock from what i remember, not the hurricane lookalike.

I'll just buy the hurricanes naked from liverpool exhaust and hpc it myself... better find guides to do it proper though. wouldn't wanna do it again when they're on the car.

[bushido]

yeh HPC looks awesome
