So I just bought FI HFC with a Topspeed Pro-1 Catback and I went to have it installed at a shop and I was told im missing a y pipe. Im totally new to all of this ive done plenty of reading on here befor I made the purchase and I was told that all I need to buy. I don't mind purchasing a y-pipe but what would be a good combination for the 2 purchases ive already made?

 

Do you have the stock exhaust on your car already? If so you have a y-pipe already.........

Run as fast as you can from the shop who told you it was missing, they're idiots.
