Going to run these headers, can anyone recommend a Y pipe or should I just have one made? Going on a stock LQ4 swap with 700r4 now and 4l80e later.

You'll have to make and fab up your own. There aren't any off the shelf y pipes.

No worries. Luckily there are enough kits out there that you can piece together a decent setup if you can weld.

Re: Exhaust advice

I have Speed Engineering long tubes. I replaced my Racing Innovations with the SE's because they fit better. I had my 3" y-pipe and exhaust fabbed by a top local exhaust shop. Wish I had a pic to post, they did a great job. The way they brought the two 3" pipes together is such a smooth transition.

Kinda wish I'd have looked into one of the dual exhaust set ups. Since a y-pipe has to be fabbed, it can be fabbed to connect nearly any headers to nearly any cat back system.
