Exhaust Y-Pipe and Cutout
The exhaust build begins! I started with vibrant stainless steel exhaust flanges, then made my own y-pipe to bring the dual 3″ pipes into one 3.5″ pipe. Since this is a street car I’m trying to keep it as quiet as possible but I want to be able to enjoy the V8 noises when I want and at the track so I added this QTP 3.5″ electronic cutout. Then after the cutout I reduced it back down to 3″ to mate up with the high flow cat and the rest of the exhaust.

The Cutout isn’t going to mess with the fuel burning or power of the car due to backpressure blah blah blah.
No it shouldn’t make a difference but it will be easy enough to make sure on the dyno.
