my mod list now consists of: lid, filter, free mods, Pacesetters LT headers/ory, and a cutout
but anyways i capped my cutout, maybe it'll improve my gas mileage a lil bit....but i was going to ask...
since i have the headers/ORY and i'm still using my stock muffler/exhaust+cutout (capped) would that create any kinda back pressure or anything?
i'm mean obviously my headers/ORY are pretty free flowing right?
and i'm sure the stock muffler is restrictive
so would it create any kinda pressure against my headers?
since the exhaust gases arent getting out fast enough or something?

 

Nothing to worry about. There's a few low 11 second cars running the stock catback around here.
