Cat Converter Upgrade

[pipster11]

Hey Guys

Pretty sure my car still has a compliance cat in it and i'm thinking it could be colapsed/dying

So options are:

Xforce - $156 pp http://www.ebay.com.au/itm/XFORCE-HI-FLOW-CERAMIC-RACING-CAT-S13-SILVIA-R32-R33-SKYLINE-/141009781243?pt=AU_Car_Parts_Accessories&hash=item20d4d681fb&_uhb=1

Venom 4" - $250 pp http://www.ebay.com.au/itm/3-Nissan-VENOM-High-Flow-Cat-Skyline-R32-R33-R34-GTST-GTR-S13-C33-A31-/251251072123?pt=AU_Car_Parts_Accessories&hash=item3a7fbb1c7b&_uhb=1

Venom 5" - $300 pp http://www.ebay.com.au/itm/3-Nissan-VENOM-High-Flow-Cat-Skyline-R32-R33-R34-GTST-GTR-S13-C33-A31-/261191191269?pt=AU_Car_Parts_Accessories&hash=item3cd0354ae5&_uhb=1

Catco Highflow - $175 pp http://justjap.com/store/product.php?productid=18066&cat=&page=1

Catco Metal Racing - $379 pp http://justjap.com/store/product.php?productid=16441&cat=&page=1

Obviously the best for the job will vary depending on power, but which would represent the best value for money in terms of "flow potential" per dollar or value for money etc?

Discuss... (hopefully this could become somewhat of a reference/review thread)

Xforce - $156 pp http://www.ebay.com....d4d681fb&_uhb=1 Had one, rubbish restrictive once it's hot

Venom 4" - $250 pp http://www.ebay.com....7fbb1c7b&_uhb=1 Both my mates have them, great quality. Core is welded in place too

Venom 5" - $300 pp http://www.ebay.com....d0354ae5&_uhb=1 A few of the boys here use/used them (I'm waiting for George to get back to Australia and making a custom 3.5" In/Out with the same body)

Catco Highflow - $175 pp http://justjap.com/s...066&cat=&page=1 Had one, it collasped on me

Catco Metal Racing - $379 pp http://justjap.com/s...441&cat=&page=1 Never used, no idea.

don't get around the fact that it steps down to 2.5 inch, so there is still a restriction

and the potential for a big epa fine

and further discolouration of by rear bar

Sounds good, pretty much what i wanted to know

Might go the 5" body Venom to be on the safe side

George (Venom owner/worker) did say the 4" body will flow easily 250kWs, but if you're shooting fo over 300kW the 5" body will do.

Just to put things into perspective, look at the Catco range, their cats are much smaller, same cell count but they claim over 300kW easily, so look at Venom cats, they could be under rating them.

I'm just a little anal, so I'm asking for a custom one to be made up for me (totes overkill lol)

[R31Nismoid]

I had a CATCO - It was bigger than 3" though, 3.5" maybe?

Worked fine @ 280rwkw. Now in a mates car without problemo i believe

De cat and E85

out of interest what is the fine for doing this?

De cat and E85

So are you saying that running E85 and no cat is legal?

Yep i have a 5in 100 cell from Venom putting 390ish kw through it! Well in saying that the gate is doing a lot of work BUT still it flows well!

I have purchased a Catco Metal Racing - $379 pp that will go on my build to begin with. If I cannot get the results I want with it I will replace with a Venom 5" body 100 cell cat as I have heard good things about it.

BTW go straight to the factory - may be a little cheaper than Ebay:

from memory $1000 per cyl +get

But e85 is carbon neutral so you don't need a cat I think

[GTSBoy]

Cat converters and carbon neutrality have nothing to do with each other.

All road vehicles that comply with the ADRs MUST have a functioning cat converter fitted. There is no way around it.

that is what I thought too.

[sydking]

He was concerned about a dirty rear bar, Many E85 users have little carbon build up.

still not legal, but hey... You rear bar is clean
