i have a new 06 civic ex, im looking for a nice deep sounding exhaust system or muffler, not the high rice sound. This is my first honda so i dont no if a deep sound is possible but if so all help is appreciated. If it is just a muffler i can do all the piping myself. Also if you know where i can get a chip or ecu upgrade for the 06 please help cause i seached and failed.

 

I've looked around and everything I see for the new Civics are for the SI only. I'll continue searching and post back when I find something.
