Yes, i thought that evofusion header probably wouldt fit. There are some headers that say they go with 1.6, 1.8 and 2.0L 4 cylinder engines, so i guess id should fit. Because Tiboron in Europe is called Coupe, and it comes in 1.6 and 2.0L engine till year 2001. So if it says that it fits on a toboron 1.6 or 2.0 i think 1.8 should also be included because the engines are almost the same. I suspect that in usa tiboron only comes with a 2.0L engine thats why many headers just say for 2.0 engine. I am looking at this header
eBay Motors: OBX Exhaust Header 97-01 Hyundai Tiburon Elantra 2.0L (item 130216311757 end time Apr-27-08 11:58:19 PDT)
and i think it should fit. Does any one have any experience with OBX? I read that they are ok, not like lets say shark racing wich is expencive as hell, but worth its money.
This is what it says for a 2.0L engine on some website:1,975 cc 2 liters 4 in-line engine with 82 mm bore, 93.5 mm stroke, 10.3 compression ratio, double overhead cam and four valves per cylinder
and for a 1.8L: 1,795 cc 1.8 liters 4 in-line front transverse engine with 82 mm bore, 85 mm stroke, 10 compression ratio, cast iron block, light alloy head, double overhead cam and four valves per cylinder.
So i guess it should fit because in seems that the engines despite tle 0.2L and compression ratio and stroke difference, they are the same. Ou, does anyone know if o can keep the ventilator for the A/C if i mount an OBX header? I would kinda like to keep it

Please tell me what you think, i really want to buy a new header because i hate the annoying sound of a cracked header. And if it kicks in a few HP-s, so the better.
