PB Blaster, fo ****zle, m'nizzle!
FWIW, the only headaches as far as installs with X-/H-pipes go seem to be regarding the one-piece units, or those whose only connection made during install is right in the middle of the H-connection. Those off-road pieces whose designs allow for one or more extra ball-and-socket type connections ahead of the X- or H-connection (
Pypes and UPR X-pipes, for example) are a total breeze to hook up, partly because you can just hang everything in place finger-tight and then cinch it all down nice n' snug when you have everything in position ... and partly because neither of those designs require you to fight those friggin' tranny mount hangers, either.
Jeg's does have a heckuva nicely designed off-road X-pipe, however, that I've been giving some serious consideration. It does feature tranny mount hangers, which eliminate the problem that my stupid cat'ed UPR X-pipe has always had with sagging under its own weight and scraping on every little bump ... BUT it has TWO ball-and-socket connections AHEAD of the X-connection. What this means is you can hook up the two downpipes off the headers, slide the 2nd half onto its hangers while hooking it to those two, and then work your way back from there. Sounds complicated, but it definitely looks like it would make the install SOOOOOOO much easier, and be a lot more firmly-mounted up in the long run than the hangerless X-pipe designs.
