Thanks adam +rep, out of curiosity does anyone know what size the mk1 Astra's use? I race in 1300 stockcars and we can use mk1 astra parts so just curious if they use a thicker pipe?
where abouts in stoke are you adam im from chesterton

Just by Blythe Bridge mate. Other end of stoke to you.
I'd put money on mk1 astra using same size.

I could be wrong but I think the secondary pipes are longer on the mk1 astra exhausts manifolds. The primary's are definitely longer too.

the std 1300 mk1 astra manifold is identical to the std nova 1300 one. the downpipes are different.

the bore is the same as the e16se/c16se, but they definitely have longer pipes.

What was that downpipe off that I bought of you last year gary?
Ahh that explains why you can have a quality nova adam in stoke on trent without it being pinched your from the posh part of stoke lol
So would the mk1 astra down pipe be a better downpipe to use with it being longer?

[garyc]

I think it would have been a nova one, but am not 100% sure.

no worries mate its hanging up in my garage as a local exhaust company bodged up an order for the next section after the downpipe and when it come it was a brand new down pipe not the section I wanted, so I kept it and reordered the part I did want lol
