Diameter of FLP Y-Pipe Merge?
Diameter of FLP Y-Pipe Merge? I was looking at the photos of the recently posted rusty FLP setup. While I assume that the coating on that set was sub-par, I was interested in the Y-Pipe merge. I have seen these in person before, but never really noticed how small the diameter is where the two pipes come together. After merging into one at the smalles diameter, it looks like the pipe then expands, to what I assume is the stock diameter of 2.75". Does anyone know how narrow the pipe actually gets? With most cat-backs being 3", it seems like a shame to go to 2.75", let alone even smaller.
Re: Diameter of FLP Y-Pipe Merge? I don't know what it necks down to, but you have to remember that the collector on the y-pipe is expanded so the 3" intermediate pipe can fit inside of it. Kinda creates the illusion that the pipe before it is really small. I can't measure mine because it's on the car, but I would say minimum 2.75".

Re: Diameter of FLP Y-Pipe Merge? Thanks for the reply, but I do not understand. The factory catback is 2.75" (both standard AND SS/WS6 version are the same). The factory catback expands to go over the factory y-pipe and has a welded on clamp. Therefore, I assume that the FLP Y-pipe should also go inside the catback pipe. This also follows conventional exhaust system practice with the forward pipes going into the latter pipes.
What am I missing here?

Re: Diameter of FLP Y-Pipe Merge? It's the other way around on the FLPs. The Y-pipe collector is expanded to fit the 3" intermediate pipe inside of it.

Here's my car. Look at the very top, you can see what I mean. The other 2 clamped locations are the same, the rear-most pipe being expanded.
