Cat

[Cookie Monster]

My car has never had a cat fitted & always passed it's MOT with even a mention.

Am I going to have an issue passing scrutineering at Blyton?

[Matthew Willoughby]

That depends how old the car is. If it was manufactured after 31st December 1999 it needs to have a catalytic converter to meet MSA regs.

It's a 2003 - is it going to be a problem then do you think based on your experience?

Phil, I'll give you a call.

[Simon.Rogers1]

Phil - short and long answer is yes it needs to have a cat to comply with our regs.

 

All of us had to do the same backwards step when the rule was introduced a few years back.

 

There are some silencers to be had that have the CAT built into the can. I have one with an FIA high flow cat which in no way hurts performance as proven on the Dyno. Won't pass a road not though!

[Cookie Monster]

Thx all

Any idea of who produces cat in can silencers pls?

 

[Titanium7]

Powerspeed do them.

[garybee]

What engine do you have?

 

I have a spare silencer with cat that I can bring to Blyton for you to borrow. You would need to have a k-series with short manifold for it to fit though.

Phil,

I had to go through this last year to enter the SC.

Mine is a Powerspeed 4/2/1.

Cost to put a CAT in and repack and return to me was £358.00 incl vat.

Very neat job and turned around with in the week.

Bit of a bugger cost wise having to have to have it done

Don't forget it's not a speed championship requirement, it's an MSA requirement so effectivley everyone competing with a road going car built after 31/12/99 must comply

 

5.16.7. Exhaust catalytic converters must be fitted to all petrol engined production based saloon, touring and sports cars, including specialist production and kit

cars, manufactured after 31/12/99. They may be specified for certain other formulae. Competitors are reminded of their obligation to maintain such equipment on a vehicle used on the highway where government legislation requires it.

Phil,

I use a standard silencer with a built in cat from a standard short manifold and the single pipe out of the side skin.

I'm actually on my second. The first I used with a Caterham long (competition)four branch manifold, and the one I'm currently using is with an SLR 4-2-1 manifold.

With both manifolds the silencer inlet and outlet need to be modified, but power does not appear to be compromised at all.

What manifold do you currently have?

[Cookie Monster]

Thanks for the responses

It's a k series 1.8 with a 4-1 manifold into a repackable can(not sure what make as there are no clues to the brand).

 

I am aware it should have one already but never had one when purchased.

Just need to weigh up if its worth getting a used cat or go with a cat in the can which would be my preference at this stage

[Richard Price]

Phil.

You have blatmail.

can you email a photo of the manifold? I may be able to identify it.
