Alright i have 2 questions. My 97 gt has 3 inch exhaust piping. The guy before me put it on. would i gain more hp switching to a 2 1/2 piping or 2 3/4.
My second question is if i keep the 3 inch can i lower my car maybe an inch and a half from stock height. I was told that my exhause will hit any bump i go over. but that inch and half sure looks alot better than stock height. any help if needed thanks

 

size of your exhaust pipes really doesnt affect horsepower until you start putting up 300+hp numbers... i believe the stock is good for 300.. the 3 inch is good for 400+ but its always nice to see big exhaust pipes coming out of a mustang, USUALLY
