Help me make a custom Y-pipe I'm putting a new exhaust on my car this year and I will be making a custom y-pipe. My exhaust will consist of TSP 1 7/8 headers to a 3" y-pipe with a Flowmaster merge (out 4") to a 4" cutout backdown to a 3" Magnaflow Quad-tip catback. I need help ordering bends that will get me from the headers to the Flowmaster merge. For anyone who has made a similar setup I would appreciate your advice. I would like to order most of the piping before I get the car on the lift. I realize I may need to get it started to get all the necessary pieces but anyone who has built a y-pipe before, feel free to chime in.

The driver side is the tricky part. For the passenger side you need two 45's. For the driver side you can use two 90's and then when you get up to the header you will need a very slight angle, like maybe a 15*.
It depends on where the merge will be. The further back it is the less angle you need in front of it. I like to get my merge as close to the trans brace as possible.
Here is one I made.
