Recently when I was changing my accelerator cable, I noticed a few holes in my firewall that were open(no plugs). Perhaps a peek up under your dash may reveal an opening into the engine compartment.
Just a thought........

Corvettes have had sidewinders on them for many years, with no issues like that. Sounds like yer engine may be a tad too rich AND you have some exhaust leaking into the cabin. If it comes down to it, you can keep the pipes on for the looks, and run a "regular" exhaust out the back. A chambered undercar system would sound just as b!tchin as sidepipers. Are ya'll CERTAIN there are NO leaks in the exhaust from the manifold dog nuts, and the welded(I assume) "U"s from the manifolds to the pipes? Are your pipe outlets turned down, or out?

The pipes are turned out and down at about a 45 degree angle. The pipe connects at the bottom of the stock rams horns via metal dog nuts. Those are double brass nutted on. The pipe is one piece from there to the tip.
I think I may like the idea of leaving the side pipes on, just have to figure out how to hang them and run the real ones out the back.
Donuts have only about 3k to 3,500 miles on them max. I'll check them tomorrow after work and see if there is any chance of loose or leak there. They've been checked several times.
I've got the new carpet set to go in later in the week so I can check for holes then.
I think it is running a bit rich. Just put a new Edelbrock carb and manifold on her a few months ago. I'll have to figure out how to lean her out a bit.
