If you got lotsa coin, the Borla is highly rated. I have heard Banks is also about to release a header $$$$$. If you is po' like me then an APN is a good choice.
I am happy with the Borla on the XJ. The only problem I had was at full flex I would hit my front drive line/yoke. Now that was with 4 1/2 of lift. Now there is no issues at 7"
Not to sure about the Banks shorty on the ZJ, still need to take out the cat.
"Automotive Parts Network", which www.ineedparts.com is part of, hence, APN.
I think I've been running mine for a little over 2 years. No complaints at all, although if I had the money, I might have tried the Borla or Thorley pieces. That header ehall has looks like a very well made part.
I've had a Doug Thorley Tri-Y on my '91 Laredo 4.0l since August of '05 & it hasn't cracked yetparty1:...but then I also had added a SS flex-joint just before the cat & also replaced the engine mounts with Polyurethanes within a year of the header install, so results may vary.:dunno:
