Is there a 3" resonator delete available for the diy exhaust job? Stainless only as i'm in the salt belt
From what I measured the Y-pipe is 3" then drops to 2.5" at the flange through the resonator to the muffler.
If not has anyone had any luck with any 3" flanges that bolt up to the stock Y-pipe?
Found this but can't find the specs on the bolt spacing, most seem to be 4.5", Stock looks to be between 5-1/4 - 5-1/2
Also not sure if the ball will seat with the stock Y-pipe
The only one made from stainless I could find that I liked was for a 1st generation Raptor with a 6.2L. Not a very cheap option, but a very well built part.
For my RC I had to cut it down for length. The taper on collar wasn't just right so grind it down by mounting in a pipe expander chucking up to a drill press.
Thanks OCmike
I have 157" wheelbase so I know I'd have to lengthen it.
Regarding the flange needing some trimming, I guess that's why the Roush exhaust has you discard their flange and reuse the stock Raptor.
Any idea of the overall length of that part?
For the record I'm 64" from flange to muffler.

I had to cut it down for length, and I still have what I cut off. I have to change oil this weekend so I'll see what's on the truck and what I have left so can estimate the original length.
OK, so I believe i have found the closest match to the OE flange it's 304SS
The 124mm centers are oblong and look to max out at 131mm (5.15") with a 1/2" bolt
Now to find a 3" stainless pipe with a ball end.

Yep...That should work. If I recall when I measured mine it was a tad under 5", which is around 124mm.
I bought the piece I think you need several years ago. Thing is, I can't remember where I bought it from. I think it was Columbia river mandrel bending or mandrel bends. I sent them the picture and specs of what I needed and they had one. This one was for 3" pipe instead of the standard 2.5" pipe.
