I got mines in December. The materials are pretty nice, all stainless steel and it comes in three sections. The flowtubes with mufflers, then the over the axle parts and the tips. The tips are real nice polished SS but mine didnt come with the necessary hanger for the tips.
The kit is real loud because it has resonators like SLP and on mine with a off orad H and shortie hearders was too loud for me I sold them. It was an alright sound but a bit crackly when you lett off the throttle and costed.
They might work good with cats and a X. Hope this helps.
