X-PIPE OR H-PIPE
Both including Cats!!!! 2 on each hi-flow cats!
im looking at h-pipe,x-pipe from BBK

X = like 12 to 20 hp
H= like 15 to 25 hp
but i want to know what is overall better cuz some friends are like go with H because its classic and old style performance and its better than ive heard that the new X pipe style has more flow and its better cuz the X chamber makes lots of power?

i want to run BBK shorty headers,BBK H-pipe, delta 40 flowmaster mufflers LOUD! trying to figure out better combination
cuz i no if u match ur exhaust as most as possible its better so using BBK and BBK is a PLUS??? help me out

 

Straight pipes.

 

what kind of combo are you running? N/A, turbo, or supercharger. The difference between the X & H pipes arent big enough to notice on the street anyway. I had a bbk x pipe and original 40 series flowmasters (louder than the delta 40's ) before i had the turbo installed. But once i had the T64 in place; i ran straight pipes off the t64 exhuast y pipe into dynomax 2.5in bullets. i would stay away from chamber styled mufflers if you have a turbo because they create back pressure ; robbing you of free Hp. use a straight thru muffler and straight pipes. my.02
