CLK 500 Muffler?
I was looking to get some more sound out of my CLK500 (deeper bass, and a little louder growl). I was looking into the Flowmaster Pro series muffler, if that is any good for this car (any recommendations? My highest I'll go is $200). I only want to change the muffler, nothing else. I would also like to know if I would lose any torque/power if I change the muffler because I have seen on other forums that people have noticed a little less torque. Thanks for all the help!




I noticed a big difference in low end and mid range torque; but my exhaust was completely diferent from stock at the time. I had kleeman primary cats, magnaflow X pipe and OEM secondary cats running to a Mag Y pipe to a 3" mid pipe into a 3" core mag muffler. Torque was greatly diminished..3" anywhere in the exhaust is too much IMO. The OEM mid pipe is 2.75" OD but only 2.55"-2.6" ID. Since you are looking to only change the muffler, I would say go with a 2.5" core muffler.
The OEM muffler is rather large in height and replacing it leaves a rather large cavern above the aftermarket muffler. IMO, the magnaflow (and perhaps others) vibrate at an audible frequency which is amplified by the "cavern". "Boom Mat" insulation / heat shield used to cover the "cavern", helps a lot. I used "Boom Mat" spray on (rubber in a can) after my final exhaust setup.
I think you can go for the sound you like best in a muffler since you will only be changing it; there is enough other "restrictions" in the system to keep any torque change unnoticeable.
My exhaust is ideal for me now (mag 200 cell cats -> vibrant resonators ->mag X pipe ->mag 14" 2x2 muff -> 2.5" dual pipes -> tips. Still less low end torque than original but the doors to heaven start to open at about 2000 rpm........

As far as a particular muffler sound preference, I would suggest listening to sound clips of different mufflers (from cars similiar to yours) and go with what sounds good to you.

Take a look and let me know what you think...
Also where did you get the dual tips? They look great, got the size/dimensions?
Edit:: haha I realize you have a quad set up now. Well, any input would be appreciated!
