Has anyone upgraded to a little more exciting option? Improved power? Are there any issues with the slabs or any of the other computers? I'm mostly interested for the D2 if/when the factory exhaust goes south on me.   Greg (Gparrish) advanced member Username: Gparrish Post Number: 1031 Registered: 04-2002 Posted on Wednesday, February 12, 2003 - 01:29 pm:    My impression on this from reading posts on Dweb since last April when I joined are that it is a wasted upgrade that makes the engine a little more noisey. I think any power increases seem to be negligable from the posts I've read, although you may be able to pick up a longer lasting material like stainless or something.   Greg French (Gregfrench) advanced member Username: Gregfrench Post Number: 189 Registered: 11-2002 Posted on Wednesday, February 12, 2003 - 01:48 pm:    How about cutting off my resonator? Will that do anything good or bad? I am sick of banging it all up on stuff.   Greg (Gparrish) advanced member Username: Gparrish Post Number: 1036 Registered: 04-2002 Posted on Wednesday, February 12, 2003 - 01:52 pm:    I don't think anyone has complained of anything bad other than additional noise. I have made no changes to my stock exhaust so I'm basing on my memory of others comments. Although, Paul Morgan cut off about 2 to 4 inches of his tail pipe and started getting a bad vibration at times. He may be able to shed more light on this or other changes.   b,johnb Unregistered guest Posted on Wednesday, February 12, 2003 - 03:13 pm:    check out the nrp site. the system is top notch. i dont have access to a 4wd dyno,so i am not sure about hp gain. but a better exhaust system has got to help.   Michael Noe (Noee) advanced member Username: Noee Post Number: 435 Registered: 03-2002 Posted on Wednesday, February 12, 2003 - 03:23 pm:    Check this out too: http://www.texasrovers.org/dual_exhaust.htm YMMV   twyst10 Unregistered guest Posted on Wednesday, February 12, 2003 - 03:29 pm:    I have a 96' D1 and I put a 3" in and out flow master on mine.... power range is longer! sounds great... You will have to find a good muffler guy to make the bends needed to tuck it good and alow for large articulation angle's. good luck!   Phillip Perkinson (Rover4x4) Member Username: Rover4x4 Post Number: 14 Registered: 02-2003 Posted on Wednesday, February 12, 2003 - 08:32 pm:    duals??   Brad Russell (Bradnc) Advanced member Username: Bradnc Post Number: 106 Registered: 03-2002 Posted on Wednesday, February 12, 2003 - 09:07 pm:    Upgrading exhaust does almost nothing for performance and is basically a waste of money. Just drill a hole in the muffler if you want sound.   M. K.

At what mileage have any of you had to address exhaust replacement issues?
