ok so i have an obdI s52. 3.5" maf soon to do injectors and software. i am also going to my exhaust soon.
currently the way i have i set up is with stock manifolds that meet up and 2.5" pipe all the way to the stock muffler. my o2 sensor is where the manifold down pipes meet.
when i upgrade im putting in raceland headers. and probably a remus or borla catback .So my question is, should i stick with single pipe back to the muffler or should i go dual pipe all the way back. and what diameter should i run for those pipes? which sounds better? and which will give more gains with software?
and if i go dual pipe all the way back do they have to meet at some point for the 02 sensor or is it ok to just put the sensor on one of the pipes(and get a reading from only 3 cylinders)?
thanks in advance
