this is how a 45 deg elbow fits. a 60 put the filter more by the old air filter box.

the end of the street pipe is a 4 inch aka the fat side, the smaller side is 3 inches, so 3 inch rubber coupler with clamps, dril a hole for the ait sensor, and paint and clamp it all up.

this whole set up cost 35 bucks. all bought local.



ive got a 98 regal with the over flow tank on the driver side, you can see the cap on the far right of the pic. no need to move it.
