I found a 3 inch cat back system for my 87 Burb made by Dynomax (part#- 17433) for $150 but it seems to be listed for only 2WD versions. I emailed them to ask what the difference was but haven't heard back yet so I was wondering if anyone knew if there was a difference between the 2 and 4WD exhaust systems for 87? I would think the transfer case would be the only problem but that is on the other side and the cat ends about even with it anyways so it shouldn't make a difference. Anyone know?
