Right 52Carl, the stuck heat riser is what got me started on fixing my exhaust or going dual. I believe that the stuck riser (in the heat on position) is leaning out my fuel mixture. I'll see if I can borrow my buddies torch and try to get it to pop loose, but catching things on fire or cracking the manifold by applying too much heat are concerns for me. I want to avoid taking the manifolds apart, but it is stuck pretty hard right now, so if heat doesn't work, I may have to open it up. Finding a replacement manifold with a good valve is another choice, but I'd want to see what I am dealing with on mine first and see if I can fix it before I buy a new one.
My thought of having a true dual exhaust instead of dealing with the old riser may have come and gone knowing that there is no guaranteed bolt on perfect fit that is cheap (cuz I'm pretty cheap). Stock seems like it is the best engineered solution and I just want to drive knowing I have things set up right. The heat riser/lean condition is also making some valves stick, so I want to get the riser valve working so I can clear up the sticky valves and not invite more of that side effect. Cruising around with a chuff, chuff, chuff sound isn't how you want to show your work.
Seems like when you own one of these vehicles, if you haven't touched or repaired/worked on everything yet, you will at some point.... I have learned way more than I wanted too, but am enjoying learning how to sort it all out. thanks for everyone's help!
