hey wasup guys well let get to the point im planning on changing my exhaust (2.5)piping to 3inch after the down pipe straight under the fuel tank slanted to the back u get what im saying.

here my question?????

would the hp and tq increase by doing this ?
do i need to go to the dyno to retuned again (im tuned on 2.5 inch piping)?

thanks in advance

 

its going to be very low if ya go under gas tank

 

I KNOW BUT ILL RAISE THE REAR UP ALIL BIT ( IM ONLY GONNA USE IT FOR DRAG RACE)

UP FOR SOME INPUT

 

You do realize you can route 3" over and around the gas tank.

 

yup maybe ill just go to the oem route

but i really need an input if hp tq will increase ??

and or if i need to tune again ??
thanks

 

Iiiiiiiiiiinnnnnnnnnnnnpppppppppuuuuuuutttttt

 

If it does it's going to be so slight that it won't make any difference.

 

So its not gonna make any difference

How come though I thought 3 inch pipe will increase hptq

 

3" will increase power yes, but going straight back under the tank isn't going to make much difference instead of just putting it where the stock systems goes. Oh and yes, you will need to check your tune when changing your exhaust like that.

 

Ahhhhhh man so if I need to tune I again ill just redo my dp to 3 inch aswell and turn up the boost (I'm only boosting 7psi right now)ill try to push it at 10psi thanks for the input

If anyone wanna add somemore details that would be great thanksss

You're going to do that while at the tuner, and not just do it/not check the tune right?
