2.5" should easy for 300whp. mine hit 370whp with no problem..

Wow this and others interesting results....but I wonder if they would pick up much faster spool with a bigger dp/exhaust.

I made 463 on a 2.5 inch downpipe, log manifold, 60 trim, on pump gas.

So yes, you will be able to hit 300 WHP

 

I made 300 on a 2.5" Downpipe

 

i made about 300 @ 8 psi with mine

 

i'm making 275whp on mine on stock....i think too many people jump on the 3" bandwagon...2.5" will work fine too

 

 

You can make a million theoretical hp on a .05" DP. Its just a matter of efficiency. The bigger the DP, the more efficient. Its just that simple.

h-t is all about the bandwagon
i run 2.5 and a cutout for the track.

 

We had a customer come to tune with a D15B7, hf manifold a 50 trim T3, and a 2.5" DP. He made 141 on our MUSTANG dyno on 7 lbs. We fabbed up a 3" DP for his car a month later, put it back on the dyno and with in 3 pulls the car made 176 on the same boost... It now blows the tires off in 2nd This is with a D15b7 so think of what you guys with the bigger engines will gain...
