I have a 99 3.9 auto and was wondering what all I would need if I wanted to add cruise control. Would it be very difficult to do? My other question is that my cat sounds like it's going bad, and when I replace it I'm not sure if I should get a normal cat or a high flow and a mil eliminator. I have a Gibson split rear exhaust and I don't know if a high flow will make it sound bad. What are some oppinions on that? Also where are some good places to look for cat's and the mil eliminator?

Thanks

 

Check with your dealer...they should have an add on cruise kit. I've only installed one and it was a loong time ago. I believe it was a dakota or durango. Check with them. Later...

 

Also, the Cat should be covered under the emissions 8 year/80,000 mile warranty. That could sway your decision on what to do w/the cat, if your truck has under 80,000 on the odometer.
