ok i now have myself a supersprint manifold and need a center pipe. where do i get one off the shelf?

if you get rid of the cat is it going to pass a mot?

and my manifold has no knuckle or flexi part, where can i get this and how much??

cheers.

Not really sure what you're asking. I'm guessing -- nothing more -- that you have a back box and the manifold and nothing else? (If you need a back box there is one in classifieds...........)

So, you need a flexi section and some pipe? If so, any of the usual culprits -- Demon Tweeks, RallySport, or maybe a local exhaust place (not Kwik Fit, they'll have it, but won't be able to sell to you).

As to the MOT, it depends. Some places will fail you on sight, others won't. Roadside checks will see you busted, without a cat. Removing the cat will have a barely noticeable effect on performance.

thanks for the info on the cat,

i have a full standard system on my car as of the minute. i have a supersprint mani at home but it doesnt have any sort of knuckle or flexi joint at the end, i have just the solid manifold and that other bit floating about in the pic on this page

but if u look at the bottom of the mani in that photo there is a attached little peice of pipe, it is that i do not have, am i right in thinking i need that to stop the manifold cracking as the engine sways on its mounts or am i completely wrong,

and the center pipe Q, i ment what centerpipe can i buy off the shelf to fit straight to the manifold and for now a standard back box?

thanks again

Tricky one -- the bit you seem to be missing is the compensator or knuckle joint: it performs a similar function, as you suggest, to a flexi section.

I think the easiest way to do it would be to find a flexi section to match up to the mani, weld that on, and then a straight section back (but the run in between is a bit complex and may require a bend in there. J333EVO has said that the cat from a V6 Rover is about the same size and shape as a Cinq/Sei one and likely to be much less restrictive..........

It's all possible, but an easier job would be to cut the cat and flexi off a SPI car (in your case a Sei would be easier, but it should be possible to use a Cinq Sporting). Get at least one flanged section in there so you can pull it all apart if need be. J33

If you're in the Liverpool area, I'd happily TIG it up for you fo a few kopeks, but would need the whole car for half a day or so. Otherwise, any of the backstreet garagistas in your locale could do it.

But to answer the original question, there's no off the shelf answer I know of.
