Off Road H Pipe Questions

[Lynx331]

Im considering getting a off road pipe. Im considering the H pipe more because it give more of a muscley agressive tone. Where the X is the more high pitched race car sound. WIll it increase any horsepower? How much louder will it actually be? I have flowmaster 40's on there right now. WIll it bolt right on? Thanks in advance

it will increase the horsepower a little bit. maybe 10? wouldn't really expect to feel it as much, unless your car has alot of other mods and a restrictive exhaust now.

i have the same setup. bbk equal lengths, offroad h, and 40 series flows. it sounds badass i think. nice deep sound.

it will bolt right on
