I'm thinking i may have an exhaust leak. i've only had the car 2 weeks and am still fixing 'little' problems. here are some indicators that point me toward the exhuast.
-'airy' exhaust sound
-power loss (?) sluggish
an exhaust leak sounds loud. I had one from the block to the manifold and i could hear it going 80 on the highway. if you really want to make sre take off the parts of the exhaust and look for the gaskets that are torn or melted.
Socialism is a philosophy of failure, the creed of ignorance, and the
gospel of envy. Its inherent virtue is the equal sharing of misery.
I just pulled the exhaust off my car for the tranny swap im dowing (in progress) and my exhaust mannifold gasket is basicaly been baked apart. I know now where my backfires were caused. We'll have to buy a new gasket before we reinstall. Then again the entire exhuast I have is pretty much all shot anyway...
why would a leak cause it to be sluggish? think about it, it only lowers backpressure. When the flex-pipe started leaking on my rabbit, it made it significantly faster.
It will be louder, just reach under the car and feel for pulses. Have a friend plug the tailpipes to force more gas out the leaks.

depending on where his exhaust leak is...he might be not be getting enough air to open his 5th & 6th ports...maybe???
An alien shape, the rotary entrances you with its combustion cycle, which seems ultimately destructive and jagged, yet perfectly smooth at the same time. Essentially a triangle spinning around within an outer housing shell, it makes piston engines cry with lack of shapeliness and originality, while causing hordes of automotive enthusiasts to pop question marks over their heads because of its foreign nature. Thinking about it for too long can give you a migraine unless you are a true fan, like the kids who draw spirographs on paper until their pen rips through to the desk, then migrate to their own skin until they're tattooed with swirling sunbursts. Those are rotary lovers. They're the most distilled form of rotary worshippers, and they love what they do.
yes, you are not correct. Less backpressure causes less low end torque, and MORE hp
This is BS. An exhaust leak, depending on the size, will decrease power. It is similar to running like a 4.5-5" exhaust which would make you think it would flow better, but in reality is overkill on your motor.
