Greddy evo is known street legal, therefore it is quiet. it is under 95 db
True about the GReddy evo muffler . . . its the same with pretty much EVERY SINGLE CATBACK SYSTEM . . .
If you wanted to hear the true sound of the Solara engine you should have gotten custom piping done . . . but 3" diameter piping is a little TOO big . . . if anything 2.5"-2.75" at biggest. Anything after that you lose power. And yea make sure you get rid of the resonator
long times ago there is a car shop did a test and proven acutally the great diameter will produce more HP. They proven that the concept that large exhaust will lost power is incorrect. It was documented in sports compact car magazine back in 199x. However, from my own experience is that excessive large diameter will result freaking loud exhaust and shift of power band-> lost low end torque but maybe gain some high end power
for example, I installed 3" catback system on my 95 240sx with ka24de, 2.4L motor. The exhaust tone is very loud and the car power band get shifted upward. I lost low end torque, but after 3000 rpm, the rpm are shooting up as i have turbo. Past 3000rpm you can feel the power are continues coming up, which are complete different with stock exhaust. Supposely, the 240sx has good low end torque and stable power band because it is a truck motor.
