1999 22zx 454mpi. It has the stock exhaust and mufflers.The exhaust is to quiet for my taste,however i dont wont a sound thats just really loud but doesnt sound good or powerfull.Does anyone run this setup without mufflers????what does it sound like?Also how would having no backpressure effect the mpi motor.I also thout about taking most of the guts out of the mufflers but leaving one of the plate in it for backpressure. I really need advice thanks.
