I have a 2k max with GAB\OSCAI and Y-pipe on order..I will soon get lightweight underdrive pulley and b-piipe, but wanted to ask everyone on this board if b-pipe showed any gains via dyno or 1/4 mile times.

inputs would be much appreciated!

 

a b pipe is basically a cat back minus the muffler- and in our cars mufflers gain 0 hp...

I gained ~15whp/10 wtq with a b pipe along with an intake.....on a 3.0 gains should be similar...

check my homepage for dyno pics.....

 

I think save your money and just cut out the resonator and remove the two crimped sections on the stock b-pipe.

 

So on my 3.0, having the Y pipe and intake, how much horsepower would I gain by adding the B-pipe with stock muffler, or just doing a full catback?

 

intake and ypipe.... you get around 15-18 hp
a full catback doesnt add much maybe 5 hp..
just get your UD pulley
