620S Exhaust Rear Exit change to Side Exit

[Neil Ramsey]

Hello

Thinking of changing my exhaust from a rear exit to side as I don't do any track days, two questions:

1. Any thoughts best type to purchase..Caterham's own (very expensive), RaceCo...not sure of any other suppliers/manufacturers?

2. Also would it be a direct change without any other adjustments required?

Looked at options a few years ago, though the world may have moved on .....

As far as I'm aware there is no Caterham equivalent side pipe.  "Lego Cat" used to use a R500 silencer with a bespoke collector. Having had a passenger ride all I can say was it was bl@&dy loud! 
Raceco do a couple of "off the shelf" pipes but at the time both needed modified collector pipes. The alternative is to get Raceco to make a custom pipe which allows you to retain your original collector.
For all the above (certainly in the past) I believe you lose having a catalytic convertor, therefore you would need to reinstate the original system at mot time. (The catalyst being internal in the original 620 side pipe)

Interesting, thank you Benton. I will update you once I have found a solution

Speak to Mike Edwards in Wisbech suprb work and his welding is an art form.

You could have the current system simply modified by chopping off at the back of the first silencer and having a new tail pipe welded on to be a side exit. Obviously this is a little dramatic than you might want but I've seen it done very successfully on a friend's similar car
