Neil Ramsey Posted September 21, 2023 Share Posted September 21, 2023 HelloThinking 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?

Benton Posted September 21, 2023 Share Posted September 21, 2023 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) Link to comment Share on other sites More sharing options...

Area Representative Nick Chan Posted September 22, 2023 Area Representative Share Posted September 22, 2023 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 Link to comment Share on other sites More sharing options...
RoflOnMyWaffle Posted June 4 Share Posted June 4 @Neil Ramsey Did you ever find a solution - I have just got a 620s in the last 2 weeks and would like a side pipe that doesn't cost more than my first born lol but also would be easy to revert to build spec, rather than cut my OEM rear exit system Link to comment Share on other sites More sharing options...
