I bet the mrt catback is quieter. It's even quieter than the prodrive I had before it, and it's a straight through design.

Pretty much the Borla Hush is going t be the quietest around. Quieter than the Evo2 I know, I'm not sure about the MRT though.

My SPT cat back is about the quitest I've heard. About the only thing quieter is a stock STI axle back exhuast. With my spt exhuast I can barely hear it's on with the windows up and radio on.

I've had an spt catback as well, and it's fairly quiet. About the same as a prodrive round tip, just not as deep. The mrt is still quieter, though.

Yea, the spt isn't loud like those civic hatchbacks, its more of a real deap tone... lower than my friends Vette, quite funny if you ask me

the SPT is quite loud in my opinion. MRT oval is dead ugly... looks like a cheap muffler with a plumbing pipe. Not only that it also has internal baffling so its not straight through which I personally would avoid. Is it quiet? yes pretty quiet.
You can get magnaflow universal with twin 3inchers tip on it. Personally it looks like stock but better looking so it does not attract police attention. Best of all its straight through, no internal baffling unlike MRT oval. Sound wise its very deep, smooth, nice burble and very quiet u wont hear the burble much at idle. You wont wake your neighbour up when going back home late.The bad thing is you gotta get piping done on it to install. Its not a problem and providing u run up to 300hp mandrel bent or press bent made no difference so its up to you.
Bolt on magnaflow?? too loud.

I just put on a Borla hush today with catted down pipe and flex up pipe. It sounds really good . You can tell it's there but it's not noisy by any means
