i did it backwords?? well, that's how i bought it. to be hones with you i don't think it was done for hp gain, but more for the sound, coz everything else was stock. if it was for the hp, the car would have had other mods on it. either way, will a magnaflow give less hp gain than replacing the resonator with a pipe??? and also, would the car get louder, or would it just change the sounds but remaid with the same loudness??
thanks
