pros and cons to 4" vs 5" exhaust system
#11
Cooler EGTs, better mpgs, and a little better spool-up are just a few benefits from both 4 & 5 inch systems, better than stock for sure. 4 inch is plenty big unless youre going for serious ponies upwards of 500. You can change the sound with different mufflers, or straight pipe it altogether 5 inch would be a PITA IMO.
