It's time to replace the exhaust manifold on the '97 Sahara. 4.0 I have read a lot of you replace the old cracked manifold with the AM Autoparts manifold. There seems to be "regular" one http://www.am-autoparts.com/Jeep/Wrangler/ExhaustManifolds/AM-10105812/255380.html
for $85.50 and then one they call "high quality" http://www.am-autoparts.com/Jeep/Wrangler/ExhaustManifolds/AM-40652416/250326.html
for $100.35. Does anyone know if there is a big difference between the two, and also is the gasket a quality gasket or do you recommend getting a better one? If so, from where? Thanks in advance for any input!
