Flowtech shorties

[yfz4501811]

I have a 92 350tbi and I was wondering if anybody knows if the flowtech shorty headers bolt-up too the stock y pipe or if modifications need to be done. Any help is greatly appreciated.

Hey yfz,

 

I just bought the flowtech shorties for my 91 Sierra. As soon as I get them installed, I can let you know how they connect with the stock Y-Pipe set up. I will actually be going to a 3" true dual system. But, will be using the stock Y until I find the tips I want. I hope to get them on this week depending on how work goes.
