since the stock exhaust of my CL-S is very free flowing from the factory, i decided to purchase twin magnaflow stainless steel mufflers and have a custom axle-back made for my car to improve aesthetics and maybe get a little louder exhaust note. so far everyone that has these has said they are very quiet and a touch quieter than a stock g35/350z. according to what i've read, headers will give me more of the sound im looking for. comptech all the way, for that.
$160 shipped.
should look something like this.
