[turnipheed]

im wondering what difference a 2 1/4 inch exhaust will make compared to a 2 inch bore, will it be significant or marginal power gains i can get a 2 inch nova system from the dreaded bay for 115 but if i even consider 2 1/4 ashley want 234 an 200 for a mangifold can any one shed some light or sell me an exhaust lol

stick to a 2" system if its going to be a standardish engine!

all ive done to the engine is weber 45s so it is standardish

stick with the 2" mate, increasing the exhaust bores on a naturally aspirated engine is not always a good thing, problems with not enough back pressure etc
