This is probably the best place to ask...

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

 

I think it will really depend on how much you are going to spray. Nitrous does like big free flowing exhaust but if only say 100 hit I think it would be minimal.

 

Agreed.
