To see what the front at the manifolds looks like go to BAT Inc, web site and look at their Y-pipe, mine is very much like it. They claim 8-10 HP increase with just the Y-pipe. With the right muffler and the different routing of the exhaust 4hp more on top of that is not an unreasonable gain. Also now that the exhaust is more open the SVT computers tune maybe working better.




Um your y-pipe probably added 4 hp casue u still have a main cat. And 3 hp from a catback with new muffler.

7 hp the most!!

I reject your reality and substitute my own.
