Exhausts

[Colin Grundy]

On the Caterham stand at the Motor Show, the SV had a competition exhaust system fitted. Did anyone notice if this or indeed the standard competition exhaust system has a cat fitted.

I need a 4-2-1 or 4-1 system for my new 1.8 K. What Caterham system do I need.

Not an expert but...

 

Ordered a Roadsport recently. Asked about the competition exhaust instead of the standard one, expecting a big credit against the after sales exhaust price (ie rebated the cost of the normal one against the price of the competition).

 

Was told £850 ❗ ❗ Considering Powerspeed ask around £500 for the after sales article I found this to be steep

 

Hence ordered the standard exhaust and will later buy competion from powerspeed or the like.

 

Also advised that the standard with Cat converter is a usefull spare to have when MOT comes round As non-cat 'performance' exhausts struggle on dB level and emissions. So one for the raod and one for the MOT / SVA - obviously not a course of action anyone would endorse on here

 

Not an expert - so best get more opinion on what I have written.

 

Cheers,

Have to say I'm a bit surprised (or am I) they didn't offer some discount off the parts price for the comp. exhaust, even if it was just a couple of hundred quid.

 

You can buy a cat by pass pipe so you wouldn't need two full exhausts, just the pipe.

 

Technically you need a cat for emissions as well as noise. But there are Caterham friendly garages out there that will sort you out if you don't have one, I believe.

 

Either that or buy an older car

 

If you search for 4-2-1 and 4-1 on the forum you'll get a good run down of the pros and cons. Adding Carmichael to the search will give you a detailed answer Basically boils down to engine size and where you want the benefits...I think most people are opting for 4-1 at the moment, but either choice will be a marked improvement over the one where the collector is inside the engine bay.
