Well being 17 I've just begun enjoying tuning up these little Hondas and getting the hell kicked by experienced racers :P. Well my ride is a 94 Teg LS, used to be a 93 Civic EX.
As for those systems, other than the fact that they'e too loud (which I don't mind)...are those two companies reliable and popular? How about the performance gains? Are they respectable.
pdiggs how old are ya anyway? Good looking Civic
