Thanks for the advice.
I'm between 2 minds, I've done some sums and can probably just scrape the amount for a 4-2-1. I'm not sure I really want to go through fitting a manifold twice. Mine has done approx 60k and has 1 stuffed stud and 3 very rusty ones...
So i've done some googling...
There seems to be 2 main 4-2-1s. Janspeed and Piper. Which is best, or is 6/2x3?
I'm leaning towards janspeed currently as Eliseparts don't sell the flexi section seperately but the janspeed one can be had form ptp.
I also found the janspeed for a fairly decent price here:
http://www.rickyracing.co.uk/search.htm ... &item=8794 though i'll have to call and see if they supply fitting kit etc...
I read through the s2 janspeed 4-2-1 fitting guide here:
http://wiki.seloc.org/a/Janspeed_4-2-1_ ... structions
and he talks about taking it off to fit exhaust wrap. Is this a requirement that should just be done from the start?
and is the fitting guide more or less the same for the s1?
What else would I need? Manifold with downpipe replacement flexi section, fitting kit of some description, some exhaust paste.... ?
Should I just behave and sort my own manifold / fit the one from Robin...?
