Finding new exhaust

[Woody2000]

Hi I have a 1973 2000 mk2 which I have been told the bore is 1 5/8” 

I am looking to fit a stainless steel system but the ones I was looking at are 1 7/8” can this just be bolt straight on or are there any changes to be done ????

thanks

go to christ witor   https://www.chriswitor.com/categories.php?cat=284

 

im pretty sure   1 5/8" is only mk1      my 74 mk2 is 1  1 7/8" 

the most fiddly  fit is the suspended clamp in front of the rear suspn X member hole 

hands and fitting all get in your  way.

Emailed Chris Whittor as I have seen a second hand stainless steel complete exhaust for a auto and he told me that mine was 1 5/8” ??

then I asked if I needed to change the exhaust manifold he said they were the same ??

so I am a bit confused 🤷‍♂️ will try and measure across the pipe on mine and see ??? 

Thanks Pete

well he  does list a  centre section 1 7/8 to fit a 1 5/8 down pipe  so a smaller down pipe must be on some models  the down pipes listed only do 1 7/8 

so its a bit imaterial the 1 7/8 down pipe will fit your mk2 manifold triangle there is only one gasket  shown for mk2 and 2.5 exhaust flanges 

 i cant see you will have any problems with a full 1 7/8 system ( but thats not a guarantee) Ha !
