TJ exhaust

[lefthand90]

OK so we've been planning to either clean or change the exhaust on '04 TJ Rubicon. The manifold had hair cracks before and seems getting bigger and hotter. Thinking of coating it but might get new exhaust instead. Eyeing for Magnaflow or Borla on http://4wheelonline.com/ due to good price but would like to know who have any of two and which gives better performance.

To be honest the stock exhaust manifolds from 2003 to 2006 are best. Doorman makes a direct replacement. Others aftermarket ones crack. I have borla and it cracked. They replaced them and so far so good. Not sure if any changes have been made in aftermarket mfg. to improve or eliminate the cracking issue. If you do replace it use a new gasket and bolts for the head to minimize leaks and loosening.
