I LOVE my BBK full length chromies!
Here's my story: I wanted to save a couple of bucks, so I bought some FlowTech (read: BLOWTECH) full lengths. Little did I know how much of a pain in the arse they'd be. I had to pull the steering shaft out to fit it between a couple of the tubes (!) and getting them to not short out my starter required a little bit of hammering. I finally got sick of them, rusting after a week or two and not exactly sealing at the head OR the collector. I broke down / gave in and bought the BBK full length chromies ($239???). I almost cried after installing them, simply because of how DEAD SIMPLE they were compared to the BLOWtechs. They don't come nearly as close to anything like BLOWtechs, and the matching shortie H-pipe bolted on perfectly. They're still nice & shiny, too! Oh, the primaries are welded inside and out to a REAL thick plate, plus you can actually tighten the bolts so they don't leak. Hope this helps!
