anyone know what the tech 7 pipework is like ? its the one @ £210

dont touch ebay pipes!
Graeme France makes his own headers and at least his are guaranteed to work right

id agree with leopard i got delkevic (i think i spelled right) pipes they are alright but surface rust was quick to set in. they arent on your list but an ebay site. S/S 304 is the lowest grade of stainless and the equivalent of your knives and forks. if you can find anything with an A infront of it is much better (A4 is the SSSHHH as marine grade). avoid the last ebay 1 as a 4-1 and has its downfalls.

Interesting - those are not our pipes - we don't currently supply Gavin at Jap4

i was contemplating buying them...they look really good and smart and especially as it says lifetime guarantee!!!!!

how long you had them?...any signs of rust?

got them 2nd hand 6 months ago ish .. been in daily use on Em's ZX4 and they're fine.. they do discolour quickly but polish up well.

they're a straight copy of the OE pipes but in stainless, so no performance gain (well, bit lighter) but they wont rot

wee heads up on different type of headers for the Nc29..
OEM headers are 4-2-1.
what does that mean?
4 pipes from exhaust ports welded in to 2 (under sump), then welded in to 1 (still under the sump) out to your end can.
some companies also sell a 4-1 set up.. now some people have had no problems with them, others had had power issues with the midrange not being able to be tuned up. the 4-1 headers i have seen cheaper.. but personalty id go for 4-2-1 set ups.
