Resonator Question.
What does the resonator do and what is a straight through?
I'm noobie but really curious because i saw a car today and sounded really nice, and he said he took out his resonator and did a striaght through. But he also had a reallly nice exhaust. If i were to take it out would it void my warranty?
Thank You

All it does it make the car quieter (a pre-muffler muffler). Taking it out will not give you any performance benefit or void your warranty, it will simply save a few pounds and make your exhaust note louder. Any muffler shop can do it for $50.

At first you will be quite disappointed with the sound difference. Especially if you are going into it expecting your car to come out sounding like a monster truck. I, for one, did. However, I think in the end it was reallllly worth it. At higher RPM's it makes the car sound more like an SL, CL, or S 55 because it gives it that beefier tone. It also seems to get a little deeper over time - it did for me at least. I say go for it, its a nice little mod and it really does make a difference in the long run. Unless you're considering an exhaust system which would be

I took my resonators AND mufflers off, and replaced them with one straight-through MagnaFlow per side. It sounded great in the shop, but by the time I had driven home (about 20 miles) I realized it was too loud for my tastes (the drone inside the cabin, especially at low RPM, gave me a headache). So, I went back and had a second Magnaflow put in on each side - that was perfect! Deep, throaty sound, not too loud while cruising but real muscular when punched. Make sure your welder knows what he is doing because if you take off the OEM mufflers, you want to make sure that the AMG exhaust tips come out the rear exactly as before. My guy put a small bead weld between the tips before cutting them off the muffler so as to maintain the pre-cut positions relative to each other. Good luck - I think it is a nice mod! Here's a picture of my MagnaFlows:
