i’ve had the magnaflow series and the afe high clearance (no muffler), both axlebacks. the mf has a light to medium sound. very tame with light throttle and and whoosh of exhaust air when you got on it. the afe is more truly exhaust sound with a lot of low freuncy noise. def much louder inside and out but a better sound IMHO. not sure which i’m going to stick with at this point.
This^^^. Well, mostly anyway. There is a good reason for the above, by the time the exhaust gas reaches the rear of the car the gas volume is greatly reduced so any muffler will have little effect. Removing restrictions near the engine where the gas volume is still high will have an effect, like removing the cat. Not generally a good idea.
