looks too stock and is too quiet for my taste, im looking for the most power acquiring (not midrange) set up whether it be single or dual (prefer dual) pipe diameter will help also, im making the system myself, will consist of rb roadrace dual header and most likely 2.5 inch piping single or dual or true dual is still in question, need advice

Then don't get the RB Header. Or if you want I will give you a hell of a deal on mine. Ultimte set-up is:

SDJ Collected header: 450

Custom Expansion pipe/muffler from Burnsstainless: 500

2 1/2" Mandral bent pipe: 80

Borla SS Muffler: 280

bigtime

full exhasut is the only way to go

just get the header from mazda trix then strait pipe it 2 3\8 back to a borla muffler
