Eventually, I will be custom welding an exhaust cutout to my downpipe before the main cat. I am wondering here, if the cutout outlet is at an angle, will the exhaust have an easy flow out or will it still attempt to go down the straight path of the exhaust?



This is just an example. If the cutout "Y's" off away from the straight flow of exhaust, would this cause turbulance in the exhaust system or would the excess pressure still find its way out just fine?

I'm looking at this to get rid of ALL backpressure in the exhaust system while keeping the catback completely stock. It saves money and does exactly what I want it to do.
