you wont gain any horsepower, you will just gain more noise
15 to 20 horse.
cat back? 12hp/12ft-lbs.
How much horsepower gain from 2 super 44s flowmaster on a f 250 with an 351 windsor
Properly installed, that system is good for about a 10% bump in horsepower...so figure about 15 hp give or take a few ponies. The system is very LOUD so be prepared to wake the neighbors.
It will gain about 2 to 3 horsepower when jetted
how much u lookin too gain?? Catback exhaust, cold intake, full exhaust.
Free flowing exhaust, nitrous
cold air intake and headers with a more open exhaust like flowmaster should gain you at least 15 to 25 horsepower
One of the easiest modifications to almost any car to gain both horsepower and fuel milage would be to make modifications to your exhaust- you can pay a custom exhaust shop to make you a cat-back exhaust system, or you could simply buy a high-flow muffler and install yourself- you should gain possibly 5-10 hp and possibly 1-2 mpg.
Advertised horsepower is..........165HP @ 3800 RPMs. 4-barrel Carb. You may gain another 2 HP with duel exhaust. but not much.
5 or 10 horse.
