Tomioka Racing 4-2-1 headers anyone ?
 

been on the lookout for EL headers that make good power like the ACE or the new JDL 4-2-1 and came across this Tomioka unit. Have not heard much about this brand. they also produce coilovers for the 86 platform. The headers also come ceramic coated. Has anyone have any experience with this header or this brand ? Thanks

Remember, that the more header design deviates from stock or from other popular header designs (eg. OFT UEL), the more it probably needs non standard ECU tune (just like ACE headers did). I'd take ECU tune into consideration when choosing headers too, and unless vendor supplies from own tuning experience some timings for start to ease ecu tuning or provides own OTS tune i'd probably go for more common varieties, as more efficient design might be handicapped by unfit tune working less efficient with it. Not always quick dyno tuning will solve the things. Ace headers with OTS tune initially were just +5whp :).
