I live an hour away from the BAT facility so I ordered the Y-pipe and the cold air intake. Drove down the same day to pick up the parts and have them installed. The guys at BAT where nice enough to install the intake and recommended a local exhaust shop to install the Y-pipe. When I brought the Y-pipe to the exhaust shop the guys there where confused why I paid $319 for a Y pipe and cat when I already had a y-pipe. They recommended installing 2.5 pipe throughout , removing the CAT ,replacing the resonator with a glasspack and putting in a bullet straight through muffler with a 2.5 inch stainless tip. They did great work custom bending the entire new 2.5 inch pipe from before the original Cat to the tip of my muffler. They even sprayed all the welds. The total cost was $300. I returned the y-pipe to BAT and got a refund. There is now a noticeable increase in the mid-range and a better launch from a standing start. This seemed to be the most logical way to have a free flowing exhaust with minimal restrictions and having 2.5 pipe all the way through. What are your comments?
