Highflow Catalytic Converter

[allthewaytotheskyline]

looking at an item...just want to know if this cat converter will fit in the standard cat converter path and more importantly if ti will flow and not restrict for over 300rwkw??

also would it be cheaper to go to an exhaust shop and get one of this size with fittings etc or take this one (if its the correct one for my application) to an exhaust shop and get them to fuse 3 inch flanges onto it and install it?

i dunno man . looks like china junk to me. spend the money and go a magnaflow metalic

[allthewaytotheskyline]

would it be stupid to gut it?

Sounds like you should stop listening to whoever is telling you that garbage, and yes, spending money on a cat only to gut it is a complete waste.

So many traders on this forum offering proven and reputable brands of high flow cats, why the need to buy a cheapo one from ebay?

A Metal Cat with the 200 cell insides is not junk by any means. This one doesnt come with flanges tho, so add the cost of getting them welded on. Other vendors sell them with flanges ready to bolt up.

They also claim to me emissions legal - http://www.metalcat.com.au/

Or you can just get a bolt on high flow catco cat from justjap with flanges. The cheaper one is ceremic core, but should be fine for 300kw. But if you have the money, upgrade to metal core like the metalcat or the catco metal core high flows.

+1 for Magnaflow, faultless product and full 12 month replacement warranty if something went wrong (unlikely to happen)

Xforce "racing" cats are also metal cores, there are a few forum sellers that do sell quality cat's.

If its $180, it has to be ceramic core, and if its not a known brand, why buy it? There are known brands fairly cheap if that is a ceramic core...

thats a metal core. and yeah it'll flow well. Look for a 100cpi item tho.

did the same, got a 200cpi from usa, welded it up with flanges, but still restrictive in a sense; put a 1" hole thru the middle

flows better

that's like saying f**k you to the greenies, and then giving them a hug?

having a 1 inch hole is gonna cause a fair amount of turbulance inside the cat and may actually cause more backpressure then a full cat.

i have a $400 metal cat here tangles if you want to try it.

its no use to me any more, if you like then you can buy it.

going cheap

got no cash, cheers tho!

doesnt smell, still does the job but is less restrictive. its still metalcore, still doing its job, but letting a little 'extra' through.

thinking last night might run a split system, two pipe from cat with short one exiting at front of rear wheel

so no one has answered if i gutted the cat would i lose any power?

would there be any negative impact on the engine or its performance in any way?

might be turbulent? decat pipe made up at the exhaust shop is two 5buck flanges and an offcut of steel...
