Exhaust Headers & Catylatic Converter
I have an 06 H3 Adventure about 76K miles. It's completely stock, runs great, completely paid for! Since waranty is not an issue nor do I have to meet any emisions checks, I am considering replacing the exhaust manifold with a custom header for the I5, and possibly removing the catalystic converter. Will this require a mod or replacing the CPU? If anyone can provide any information I would be greatly apreciative.
great forum, Too bad Hummer is almost history. I have watched on the sidelines for years.
