After reading about de-cat pipe giving slightly more torque, less drone for the HKS/Invida, Weight saving and better throttle response I found a lot of negative comments about putting cats back in at MOT time. So Help here from the Likes of Lurking Lawyer, AquilaEagle, MB, mikey k plus others would a sports cat be any good?

I have Friend that works for http://www.pipercams.co.uk/exhaust/ that said if there was enough interest they would develop a sports cat.

These guy do a lot of work for the like or WRC and touring cars.
They also do CAMS and Manifolds.

So is there any interest or benefits here?

I think it would be interesting to know a ball park figure Stefan.

Cant at the moment Vixen. Think Numbers of people intrested may
determine that but will ask.

They would like some details like

1 - What bore size the exhaust section of it should be
2 - What size cat they would like us to use
3 - What CPSI (Cells per Square inch) cat they would like us to use

we can ask for advise if needed.

I recall a thread about replacing a broken stock cat, for which Honda charge a vast amount. Toda have a high flow cat which is a fraction of the cost of the OEM item.

I don't think Toda do a HFC. They do a resonated decat which is often mistaken for a HFC though

Berk Technology do a HFC and there's a long thread on it over on the US board GTS Chris supplies them over here and they cost around

AquilaEagle

Why LL and I would have a clue I don't know Stefan

I recall reading something about these, but have no 1st hand experience I can share, unfortunately.

Any links to the Berk HFC mentioned above? I always thought they only did a test pipe for full on decat purposes

I popped the decat on the Invidia, cant notice any difference in power or torque.

Cant hear any difference either.

But thats because I am now deaf.

I have a brand new Berk High Flow cat for sale if anyone is interested. I haven't had a chance to put it in the for sale section yet.
