Hi All, I'm looking for some help to better understand comments and info on the multiple air and exhaust threads.
It seems like S&B Air intake and Borla touring cat back exhaust are relatively common mods among many AT4 owners, and people seem happy with those mods.
What I would like to better understand is, on their own, what affect will those two mods have on performance and MPG efficiency if you add them–but do not do any chip or tuning.
I've seen multiple comments saying it will do "nothing" (other than sound) unless you tune it, but I'm not seeing on these threads what the preferred or recommended methods are for tuning, or the pros and cons of tuning. Could anyone please provide insight, or direct me to another thread, on what chips or tunes are recommended or not recommended, needed or not needed, to pair with this air and exhaust combo to bring the most out of those mods for performance and MFG efficiency?
Thanks!
