Hey, so I have an 04qc with the 4.7 and I found a y-pipe on autoamything for a good price. When I go to buy its gives me an option of choosing the inlet and outlet size. My question is which do I choose. I plan on keeping the stock headers.

Hope that link works since I'm on the cell. Thanks for the help and feel free to throw out an opinion on a "lil louder than stock muffler" thanks again

 

Bumpage...anyone know

 

Hey man I talked to your brother at school, he says you moved up north?

 

my brother isnt the brightest. Im still living in cove, hows your truck running?? any idea about my y-pipe question? Now that your leveled you need to buy my 20's

 

Y keep the Y pipe ?
Y pipe is not going to balance out the ex as the ex pipe of the manifolds is not equal to begin with, adding a after market y pipe and keeping a stock muffler, or cat back will not give you the same increase in h/p or torque that a true dual will give you.

 

Well what im planning on doing is replacing the Y with the magnaflow one, then from there back run the exhaust the stock route but with 1in. larger diameter piping and a magnaflow muffler

 

Bump, anyone know? Really wanna order this

 

I'm not sure that the 4.7 runs the same diameter exhaust as the Hemi. But if'n it were me I'd climb underneath my truck with a tape measure anyway before I'd ask other people what diameter MY pipe is.... Just sayin'...

 

I actually have a magnaflow y-pipe that I put on, and then got taken back out. I lost WAY to much low end without the restriction it put in. Huge difference with my exhaust setup

Just get down and measure it, I dont remember what mine was but mine is different after the Y
