Cheap knock off of what? Does anybody in the Accord section have any clue about performance here? Not really knocking anybody, but I am sad for you guys here... maybe I can help you out a little. I mean this respectfully so please don't think I am trying to be an ass. These headers are made by RMF which have been on all of the fastest all motor cars around... such as Erick's Racing, Leslie Durst, Bisi... just to name a few. The header make an easy 20whp over DC and even makes more power than my previous SMSP header.
This particular header is designed for my specific engine set-up (stroker), but the look is almost identicle to the "production" run RMF headers. The production run headers actually make 15-20 whp over DC. I will post a dyno, but I feel that it would be meaningless because it seems like there is little understanding or interest in NA performance in this forum.
