True ok somebody else did say this also. Now ive just recently spoken to darren difillipo and discussed a system. Main questions to date twin 3" or twin 2.5" (i want to go tha 3" but am told is overkill unless cam/head is done.) or should i just go it would it sound better or worse? been assured there wouldnt be a drone, just the 2.5" would sound more aggressive when given to it and the 3" would be a louder idle. i dunno, i wanna think going tha 3" wouldnt be a mistake but its a bit of a catch 22..? at least then its charger ready. Also leaning more towards 1 3/4, 4into1 headers due to them being better low end with little work done to motor while tha 1 7/8 would be better top end after cam or charger. gettn closer to purchasing something but want to be 100% happy i guess.
