Please please please for the love of GOD stay away from pacesetter!
I speak from experience.I bought a set many years back and they were a terrible crush bent black painted nightmare.
Mind you these were headers for a 5.0L mustang,but the quality was atrocious!
The welds looked as if a 4 y/o tried. :shock:
I cant say much about chikara,but I've heard good and bad.
My .02 save up a lil longer and buy quality.(DC,Borla,Apex)
