Totally agree with you there Johnny. In reality if we had more time we could have seen the max power on stock manifold without mugen twinloop and then the same with the Tegiwa.
Ground clearance is excellent, The quality is great, obviously not to SMSP or HYTECH standard but these two brands generally cost more than double the price of the TEGIWA. With regard to fitment, as mentioned one of the bolt holes is a couple of millimeters offset. I've no doubt Tegiwa will have their manufacturer correct the CNC program for this ASAP.
Either way to say the manifold was the only thing changed, it gave great results once the ecu was tuned and is definitely good value for money! Appearence is great too. I'd certainly reccomend it for the B16b.
Graph will be posted at the end of the day tomorrow when i have chance to copy them off the dyno.
