does anyone have personal experience with these types of headers for a ka24e sohc, BBP racing and OBX do they fit without flaws? where did you buy yours? are they worth the money? can anyone show me pics if they fit correctly.

My general experience with OBX headers has been negative. Installed on a few of my own and other cutomers cars and the fit and quality is mediocre at best. Remember: you get what you pay for. Will they work? Sure, but the headaches in getting installed right and the durability just isn't there.

I've had my OBX for several years. After welding a 2nd O2 bung closed and several attempts to heat and bend away from the steering, it still interferes with my steering on moderate to hard right turns.

you have to keep in mind that you are adding a custom item to your exaust system that was never intended to be there in the first place...so custom item means custom fitment to!..its nice to have those perfect fit headers that cost and arm and a legg..but i see nothing wrong with a EBAY header ither..it does the same job...looks the same..and if ya rip the shiz out of your exaust system on a curb check..ya can allways ebay another system for next to a set of tires on ebay...but....if you have a perfect trailer show car..they ya..spend the cash...in a realistic world, cheeper can be better..its nice to buy guess geans...but when your strapped for cash..the levie's at walmart for 19. bucks work just fine.

no they do not... the water jackets around the 4th cylinder do not match... i was going to do the same thing... but i cant... but the de is ont around 300 with about 100k miles... so theres not really any reason not to go that way...
