Catalytic converter upgrade/recommendations

[Nissan_S15]

Hey guys,

I recently had issues with my 5 month old Tomei Expreme ti exhaust system, which formed a large crack 180 degrees around the pipe.

Which I am currently in talks with the company I bought it from in order to get a replacement.

The new exhaust system, once I recieve it, will be installed by Horsham Developments, however I am thinking of installing a better CAT at the same time as well. Just so I know everything is brand spanking new

I am currently looking at this particular CAT, which ive heard good things about and just wondered what you guys thought?

Its a high flow Kenobi metal CAT, which apparently gives better performance compared to the factory one.

Otherwise would you guys be able to recommend any other brands or should I just get a new replacment factory CAT?

By the way my S15 is a Spec S 1999 and currently has standard CAT and a Tomei Expreme Ti S14 exhaust system, if that makes any difference.


Regards

Ash

Looks pretty decent mate, any high flow cat will be an improvement over standard . mine has a nismo high flow cat but they are about £1100 if you can even get one now. Can't believe the tomei cracked? Very odd

Decat ; )

Yeah get a bolt in decat pipe. Don't waste your money on a high flow cat for an NA. It will make no difference! And if your old cat is ok don't even bother buying a new one. It would be like buying a brand new car when your old one is good still! Just so you know its all new!

Yeah, just de-cat. Anything else is pointless.

As been said, for an NA a high flow cat is a waste of time, even a decat wont give you any extra power. I would keep your stock cat if it's in good condition

You live in the uk why have you even got a CAT on your car?? you only need it one day of the year!

Wish we had the same options, here they will bend you over big time if you don't have a Cat..Very expensive fine too

Here in NZ, it is not a requirement to run a cat. Last time I had one was 2002.

Isn't that after the car's a certain age?

Decat ; )

seconded, although your car will sound ridiculously loud as it was loud enough at santa pod

Not that I've ever experienced, and I've never failed a WOF because of no cat (since 2002). Friends with other makes and models of cars have also removed them, and a mate with a workshop regularly has to make decats for customers.
