flowtech longtube headers
DO NOT WASTE YOUR MONEY ON FLOWTECH ANYTHING!!! i dont care that they are a division of holley. they suck! i bought some headers from them a while back for my truck and i spent more time with them off trying to get them straight and welding up holes in the primaries, THAT THEY CAME WITH FROM THE FACTORY, they still wont seal and ive used copper, graphite, and dead soft alum. gaskets. waste of time.
Sorry, personal experience here, on my car and one of my really good friends'. FlowCRAP is junk. Absolute, total, without exception JUNK. They never completely seal (2-piece construction on the driver's side), the flanges are scrap, the fitment is worthless, and the install is worse than a 1-piece. Save your money. I DO speak from personal experience here... I had the engine jacked up, the K-member out, and STILL couldn't get the things to fit right. I ended up having to throw the OEM exhaust back on, and take it to a shop. Thank God my mechanic is as much of a stand up guy as he is, because I paid for a 4-hour install... took him almost 10. My buddy, with the 'new style' Flowtechs, has had much the same problem I have, WITH Stage 8 bolts. When I do my motor swap this winter, I'm thinking about springing for the SLP stainless setup, otherwise I'm probably going BBK. These pieces of junk don't seal. Period. I've tried all kinds of high-temp sealants, and my buddy is going to try V-band clamps, but it's just unreal how poorly everything fits together.
