As the topic description says, there seems to be a lot of people after high flow cats at the moment and I'm considering one as well.

Personally I'm after a 63.5mm (OEM size).

UPDATE!

I have managed to get a 10% discount with one vendor on the 63.5mm, which should bring it in at £202.5 inc VAT and UK mainland delivery.

They don't currently have 11 in stock, but are going to try and source more from Berk, although their products are quite often back ordered or delayed.

So, once we get a current stock level, I'll pass on the relevant discount details people at the top of the list on a 'first come, first served' basis.

Please shout now if you no longer want one.

Sadly they do not have any 70mm in stock, however I will update if they manage to order any.

 

Please read the Group Buy Rules before proceeding further with this, thanks.

Thanks lovegroova - I read them and just wanted to see what the general interest is and if any sponsored vendors might come forward with an offer, or if anyone wanted to recommend somewhere.

 

I'd be up for one on a group buy.

 

You'll struggle with the dollar as it has been. But give the existing traders the chance first.

I'd want a 63.5mm

 

I would be very interested too.

 

I know this is probably dense and I have tried google. But want to hear real people's opinions on the benefits of a HFC, sound & performance changes with oem exhaust etc.

 

im after one as well

 

Let me know any Berk requirements

Thanks

Andy

 

Link suggests HP gains %5-10% engine dependent of efficiency of oem system.
I noticed and mild increase in noise and power approx %5-10 with my oem exhaust system
less restrictive so runs leaner and that helps power availability.
Getting the gas out quicker helps without affecting scavenge chariristics compared to a decat.
A Gernby pipe is one of the best set ups available in the US or was once,but very expensive.
