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!!!!!

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

> i think i paid less than Jap4 are asking from you direct.. + the adapter.

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.
