I have a 6th gen V6 Sedan, and I'd love to buy some CL-S Mufflers for it ....Does anyone know if i'd be doing any modifying to the exhaust system or the mufflers them self to make them fit?

The hangers need to be modified because the CL-S mufflers are longer than the Accord mufflers.

Just the hangers? So they bolt right up eh....Do you like the sound of them?

Yep, after you fix the hangers, they bolt right up. I like the CL-S mufflers, they sound a little more aggressive, but they don't drone at highway speeds. You can take a road trip and not feel beat up. In addition, they look a lot better than the downward pointing stock mufflers.

I had tried Comptech and Thermal exhausts previously, and the nice aggressive sound around town they both produced turned into headache inducing droning at ~2750 rpm (around 70-75 mph).

Did you buy them new? And if you don't mind me asking, what did you pay for both?

I bought them for $100 from a CL-S owner when he upgraded his exhaust.
