competition 4-1 exhaust K series

I think this might be how it goes?

 

If your sl was made by the factory it needed a exhaust with a cat, so no com 4-1 exhaust.

 

If the sl was home built or by another compony then it got round the cat reg.

 

I have a late sl #148 and it does not have a comp exhaust, but it was built by CC in 2001 so would need a cat and needs one for the mot.

 

hope this helps

my sl #147 didn't come with a decent exhaust, I thought it did, the sales boy said it did, but it didn't

 

there must have been a point in time when the spec changed, but when I am not sure *confused*

 

making the hole is relatively easy with a flap wheel as hoops suggests *thumbup*

Blimey ..... what a can of worms !!!

 

As the forthcoming proud owner of said exhaust ... I now need to investigate the fitting. As I understand it, the main problem is the hole.

 

I have contacted Caterham who have quote approx 3 hours work therefore approx £150.

 

Anybody willing to provide a template of their hole (oooooh ere misses) or pass on any tips.
