Yes the clutch works awesome. The brace I added really helped. From what I understand, these pups had issues with the firewall flexing right from the factory, so the flex I saw was probably there all the time. It's not anymore <img src="/forums/images/graemlins/smile.gif" alt="" />

The radiator cools well. The gauge stays between 1/4 and 1/2 the way up no matter how you're driving. It will be interesting to see what happens as the weather warms up, but I don't anticipate any problems. At low speeds the fans work awesome and keep it nice and cool. Before with the C223 this thing would over heat coasting down hill with the engine turned off <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" />

Oh and even without exhaust, it's not very loud. The in-cab noise is louder than I like, but I had my friend drive it down the road while I watched and it really wasn't that loud. I think full exhaust all the way back without a muffler will sound awesome. I can always put a muffler in later, but I don't think it will be necessary.
