I just bought a 97 corolla for a work car. Still needs a system, but the engine is pretty loud inside. Sounds like a constant 25hz wave or something... The exhaust manifold is cracked and I'll be replacing that soon but is there any other reason it would be that loud. It's only inside the car too, outside it doesn't sound very loud at all. I just hope I can figure this out before I finish installing my system.
