If you do a forum search a few threads will pop up like this example:I have a 1984 k20 6.2 looking to buy a exhaust for it. what would be a good exhaust? I need a complete system from manifold back.
You would have to custom build a 3", Rockauto only has the stock size, 2.5" I thinkI'm looking into a 3 inch dual exhaust. If I go that route do I need to modify anything else? Is there a down fall using a bigger exhaust ( running hotter)? Also who sells a 3 inch dual exhaust?
