I've been waiting to get a new exhaust for my 99 EX, and I'm wondering if APEXi's DUNK series is something worth buying into. I found it for $155 (N/A - 60mm inlet) or $165 (Turbo - 80mm inlet), but which one will fit my Civic without fabrication? Also, since my car is N/A right now but I plan to add a turbo in the future, which model would you recommend? Also, anyone know if these are expandable, as in will I be able to add the rest of the cat-back system if I want to in the future? Any advice is appreciated.
