Stock exhaust + nitrous?
What kind of gains (REAL WORLD) have people seen going from stock exhaust + nitrous to catback/cutout + nitrous?
TBSS has 100% factory manifolds/catback. Just curious what kind of gains could be expected with a cutout or catback with stock manifolds.
Been awhile since I've had an fbody but I remember significant gains on spray with headers...not trying to get headers but maybe some other exhaust work
