What truck do you have?

 

[aaronmiiller]

06 big horn 4x4

 

[snrusnak]

With the hemi right?

I think the y pipe you'd need is dual 2.5" inlet / single 3" outlet.

 

[aaronmiiller]

Ya with the hemi. I read elsewhere the actual stock exhaust size before the Y is 2.25"?

 

[snrusnak]

I thought it was 2.5". Let someone else verify. I'm 99% sure it is 2.5" on the 4th gens.

 

[aaronmiiller]

Anyone have a clue?

the factory pipes are 2.25" the problem is that most places don't have the dual 2.25 to 3" Y pipe so everyone was having to use the 2.5 to 3" pipe.
