exaust systems. yer 3/1/2 blows off what 350, or more h/p double that 700h/p or more yer. standard is best am i worng.:LOL:
3/12 all im saying is that the standard exaust system handles most mods , the cars run well with out spending, mega on exausts, and loud ones in and out dont waist money on h/p you havent got .
Standard exhaust has restrictors in it. You can get a significant power increase by changing it all to a twin 2.5" straight through exhaust sytem. For almost everyone on this forum, anything more than that, can reduce low end torque and create more drone/noise.
