I considered my exhaust too loud also. Checked the entire system. Found a crack in the front neck of the cat. Had it welded. car is quieter, but still somewhat loud, in my opinion. Sounds to me like the exhaust manifold gaskets, dealer says their ok. It seems louder at idle or slower speeds, highway driving is fine. I have to admit it has a nice thoaty sound to it. Especially when letting off the gas and coasting, rumble, rumble, rumble. People have described it as a brute, and it is. Although a mellow and refined one...... Describe what you mean as too loud.
