300-400 sounds ok still if theyre stainless.

as long as they wont foul the clutch slave on an adm ae86/ae71 bellhousing. this is something to consider if you plan to market them in Australia.

even the $1200 dollar merge collectors we use from the states dont do this, all pipes butt up at the same distance.
on a small horsepower engine like an atmo 4ag,18rg etc you would find it hard telling any diffrence at all. you will make far more power with a proper merge collector and with equal length pipes tuned to the length to suit the engine

you exept to get good well tested stainless headers for $300-$400!
so i take it you would prefur the stainless ones for there look than dyno tested mild steel ones?
