and when it splits into 2, it goes to 2.25

I am not any kind of authority on exhausts. I suspect the 3" figure would be the correct value though, because it's a "choke point" (the narrowest part in the new exhaust). You're not going to get anything through the 2-2.25" pipes that doesn't go through the single 3" section first.

88Racing is more knowledgeable about exhausts though. He might notice this thread and chime in.

If you have maintained the original stock "Y". This is the pipe that comes off the headers with the cats and o2 sensors and then merges together to the point where you'd put a cat back on.
If this is the case then just put down Borla cat back system 3" SI/2.25" DO.
But..........
If you split the "Y" and put truduals under the truck then Bill needs to know this.
Hope that helps.

Thanks 88 =)

Eh, sorry, but yet another question.
Does it come with 3 stock tunes? And when I get my custom tunes, will I still have access to the 3 stock + 2 customs. Or is it limited?

So I would have for my case;
stock tranny
stock 87-tow
stock 93-per
custom 87-per
custom 87 eco

Is this correct?

[88Racing]

What the gryphon comes with is what we call "canned" tunes.
It's layout is like this.
0-Stock.
1-Tranny only. Canned.
2-Tow tune. Canned.
3-Perfomance. Canned.

The gryphon can never have anymore than 3 tunes loaded in it at any one time.

My layout is this.
0-Stock
1-87 Performance tow(custom)
2-87 Performance(custom)
3-Performance(canned)

Canned tunes fit a lot of different f150's but custom tunes only fit your truck.

So in your case.

stock tranny(don't need)
stock 87-tow
stock 93-per(do you want this or keep everything the same octane?)
custom 87-per
custom 87 eco

Just some ideas.

88racing, what tune do u use for daily driving? also, how are your 87perf. tunes different?

[88Racing]

My 87oct perf custom tune is what I use the most. That tune is geared for gitty up and go. It also has max economy with it.
My 87oct tow perf custom tune is for when I pull loads over 2500 lbs. That tune provides power in the lower rpms to help get your truck going when pulling a trailer.
Both of these tunes have different shift strategies also.
Hope this helps
