i have 1989 integra and i need suggestion on a high performance muffler that will help gain more power. plus i'm looking for a headlight host so i can add an hid lights
full exhaust is the way to go.. it all starts at the maifold.. stock cast maifolds suck and dont give off a good sound, and a high flow cat with a good axleback. or do a custom.. eitherway do it right!
