A bit late in the discussion, forgive me I'm a newbie, I bought a 4-2-1 on ebay for £39 plus delivery. All in all less than £50. The dealers obviously buy these in large numbers at a cheap price then need to turn them back into cash quickly. Wait until you see one for auction starting at 99p then place a strategic bid at your top price, it may take 3 or 4 goes but you'll get a bargain. Fit was bad but nothing that couldn't be put right. :lol:

it can't go wrong! Cheers for having a cheap header! Still there are noumerous shaped and quality cheap headers. Some of them fail, while some other last for long time. Are you happy with yours?

Makes a great exhaust note and after 10,000 miles or so still in one piece. Only problem is a lack of flex section, it created stress elsewhere and reminded me that the middle box was 12yrs old. :o

our headers don't have flex pipe (donut) but they keep the stock bolts with the springs around them. Donuts tend to brake all the time.

it doesnt say how much hp gain it gives ..any idea ?

If you talking about the 2nd photo's header it is 4-1.
Theoretically it is good for high revving, I want to say it performs better at high revs.

The first photo's header is classic 4-2-1 header.
Personally I don't have it but you can read many reviews in this forum for this style of header! ;)

The below header is 4-1 from IRESA for D-series and it is like the B18C ones for high revving!!
