Heelo all, I just signed into this forum and looking for sound afvise on a good all around cat back system for my 2007EX. I am lookoing for input as to what brands are better than others and of course which increase performance over the others. Any help will be greatly appreciated.

 

please read the stickies. I'm not sure you'll have that much of a selection (compared to older generation civics) considering how new your car is though.

*edit: checked procivic.com for ya. GReddy and Magnaflow both have cat-backs out for 8th gens, and they're both very reputable companies.
