how much power would there be to gain with a 2.5" collector header v.s a 2" collector header
i mean u can get the 2" ssac headers for really good deal
and i can't find a decent price on a 2.5" collector anywhere
i'm gonna be running a pretty much free flowing side exit exhaust
so i just dont know if the more expensive header is gonna be worth it
please dont do side exit on an NA car....sounds terrible
