Hooker Super Comps also fit without too many headaches, I even got mine in without unbolting any engine mounts, and I didn't dent any pipes to make them fit. The part # for the HSC's is 5115. The 5115's go above the steering linkage just like the Doug's and the TTT's. They also fit with the standard boat anchor starter (which I have). The price is pretty comparable too, $689.95 at Summit for the ceramic coated version. They're also a 1 3/4" header all the way through, so if you're planning a BIG hp engine you might get some more flow out of them vs the stepped TTI's.
I also mention them because they've been around forever (Doug's too) and I've seen several sets at various swap meets. I bought my set of ceramic coated super comps for my Challenger for $200 in great condition, just a few scratches in the ceramic, no dents. I also bought a set of super comps for my Dart for a whopping $150. Be sure to get the Super Comps though, not just the Comps, since the cheaper Hooker Competition headers go below the steering link just like the other "cheap" headers.
