inlet/outlet sizes
 
I've been doing a lot of research on the forms and it looks like the 14inch magnaflow with the Y-pipe.

I have a bad back and I don't really want to get under the truck too look when so many of you probably know this.

So, anyone know the inlet/outlet sizes i need for the muffler and Y-pipe? If you had links to the ones i need that would be awesome!

Is this the Y? (http://www.ebay.com/itm/Magnaflow-10...578204&vxp=mtr)

The muffler you need is a single 3" inlet and dual 2.5" outlet, and the y-pipe is the same. Part # for the Y pipe is 10778 and the muffler is 12198.

Thanks!

Now I am a little confused, why does the muffler have dual outs and the Y-pipe have a single inlet? Is this not what the exhaust looks like?

I guess I should have asked...do you have a single or dual rear exhaust right now? The muffler I listed was for trucks with the factory dual exhaust.

Talk to Exhaust Junkie from BSM Exhaust works. He will point you in the right direction.

I have the factory dual.

But why would the Y-Pipe have a single inlet? I thought (i may be wrong?) but doesn't the exhaust come out of the muffler as a singlet and then split at the y-pipe?

If you want to use the same factory piping then the parts Matt posted will work.

Your diagram posted is single exit but you stated you have dual exit.

Think it was his wording.

Magnaflow Y 10778 is 2.5" dual inlet and single 3" outlet
Magnaflow Muffler # is 3" single inlet and dual 2.5" outlet

The y pipe has 2 inlets and a single outlet.

the Y pipe goes up near the engine
it collects the exhaust from the left & right banks of the engine, stock ones are flattened & restrict flow

from the Y pipe to the muffler is a single pipe
after the muffler 2 tail pipes run either to the rear bumper or to the sides
