Remus is like straightpipe except theres 1 helmholtz resonators on each side, which gets rid of low freq sounds like drone. But it gets obnoxiously loud + raspy when u start touching primary cats. This is because its a "True dual" setup. No H pipe no x pipe

or get any valved exhausts like fabspeed, gthaus GTC, Fi, Mad, valvtronic, ipe, armytrix.
These can go quieter or quiet as oem when the valve is closed, but never recommend going full throttle with closed valve setting.
depending on the brand and how they engineered their muffler, theres gonna be a lot of backpressure, and u dont want that went the car is revving out.

Akra is just expensive just minimal sound increase + very refined sound (not tinny, raspy, and cheap sounding). but the valve function is noticable than oem.

Dinan exhaust is copy of akra. minimal sound increase.

also if u want a higher pitch smooth exotic tone go with a setup with an x pipe. (eisenmann, awe, fi, valvtronic, gthaus)

If u r looking for a v8 growl go for a setup that has H pipe for the mid pipe. (Mpe, Akra)
Dinan is a copy of akra? Dinan is SS and Akra is Ti.

Id say that Akra and MPE are closer to each other in terms of sound.
