If you are thinking on purchasing this product, do so with no worries! Yes, it is expensive compared to other headers on the market, but it is well worth the money spent. The fitment is amazing, does not rub against any other components in the engine bay, and even has a spot to rebolt the dipstick on the header! Welds are top quality, and the paint is amazing on the mild steel (DC Sports no longer sells the stainless steel header). The only complication was that it was difficult to get into place, but that would be with any one piece header, and you have to extend the oxygen sensor (O2 Sensor) because it is placed further down from the stock placement, it only requires some shrink wrap and same gauge wire. Also, prepare to get some PB Blaster (AKA Liquid Wrench), I have a S13 with no rust from the southeastern part of America, but those bolts were rusted pretty good from being on the car untouched for 20+ years. Again, this is an AMAZING buy, if you have a strong KA24DE and tend to keep it for a while, buy with confidence!
