Engine question

Got a 94 LX 1.8 DOHC. Every now & then, I get a bad rattle under the car (sounds like in the exhaust) and a BAD air noise like a blowoff valve from a compressor. Yhe car will then act like it's running on 3. Any idea's? I think the exhaust is plugging, causing too much back pressure, but I'm a suspension & stereo guy. Engine guru's, Hear me!!!
