Whats The Deal With Xforce?

[WARLORD]

Overkill on a standard car.

tell me someone who has left their car standard once they start one thing it always ends up being another,buy for the future and you save buying it twice .

overkill today perfect tomorrow.

I was thinking the cat might be a bit restrictive so gonna try a decat pipe next time it goes on the dyno to see

It still doesnt feel to bad I just want to eliminate that as a suspect, Tune might just be a little out so will see next time it goes on the dyno

The full X-Force exhaust system is great, I love the sound it puts out, nice RB sound without being overly loud

Guilty...............

Mine's fine. Had it for almost three years now. Did a dyno with it in 1 year ago, pulled "195rwkw" quite easily at the time. I'll be damned if it's restricting my exhaust.

If the car is tuned right..

My Xforce cat got kinda shrivelled up near the back and blocked SOLID to the point where the turbo blew a chunk of gasket out due to backpressure

this *may* have been due to running an ECU with no 02 sensor though.

That'll do it every time...

+1, got mine installed couple of month back, car seemed to pull a bit harder & boost seem to come on faster & its a lot quieter than my old exhaust (stock pipes with a cannon wielded on), no longer have the annoy drone at idle & doesn't sound like a lawn mower when I'm just driving alone at 60km/h at 2krpm.

Didn't knew that they weren't EPA approved though... good thing I still have my old exhaust somewhere...

i put on a 3" hi flow xforce cat over 1 year ago and i noticed a more free flowing exhaust with the odd back fire here and there on cold nights

the odd backfire would point towards airflow meter, or on a cold night the air is alot thicker (more oxygen in it) could be a bit lean, reasons are many for back fire, no offence but your giving miss infomation.

[BensDR30]

A 'pop' in the exhaust is too much fuel, a 'pop' in the intake is too little.

But as for the causes of the AFR, there are many.

cheers for the replys guys, guess for what im going to use it for it should be rad.

thanks.

[boostn0199]

so just wondering for about 300kwaw will i get away with the cermaic xforce cat or do i have to go to the metal

[bozodos]

only girls run cats

do what you want, theres arguments for and against here

[boostn0199]

yeah or i was just thinking of banging the stock cat out

[NZM.031]

bakes got a metalcat put in his... didnt make a lick of difference to the power but gave a tad more torque and a bit more feeling under foot.. doesnt throw flames like it used to though.. and for the record.. bakes is a girl.. arent you bakes

[boostn0199]

are metal cats street legal? Do they still make your exhust smell the same as when you have a normal cat in the car?

[Moodles2]

Just Jap have told me they run a ceramic Catco in one of their 300awkw GTRs..

Just don't get Metal Cat confused with other companies "metalcats", Metal Cat is a Australia company that makes cats with metal castrates, The X-Force cat (copy of Metal Cat's cat) with the metal castrate isn't EPA approved (none of their cats are, its just X-Force trying to cash in on the metalcat name).

yeah thats what i was leaning to.

They are a good thing, I am running the Catco Metal Cat in my Evo and have been for almost 6 months

Dont supposed anyone has tried the x-force exhaust manifolds? Im thinking about getting a low mount one. one of my mates rang them up (the place he works for is a dealer for x-force) and he told me the guy from x-force said they had early problems with the manifolds warping but they have fixed that in the latest version of them.

Just wanted to know if anyone had seen/used one?

[Tony de Wonderful]

Is it worth getting an xforce 'zaust or spending a bit more on a stainless HKS system? Sound = same?

I was thinking of a HKS silent hi-power from the turbo back w/ 3" dump & hi flow cat etc
