Thank You very much for your display of maturity. We really appreciate it when we can keep drama outta here!

Anyways, personally, if you have $1500 to spend on mods, I'd stick with a 3" because you are probably going to go with stuff like the HV3 or cam that are going to add HP. You don't want to go too small and then realize you need a bigger DP because of how much you modded.

ok i am surprise i have to do this...

2.5 is more than plenty for a n/a that plans on staying n/a

if you plan on going supercharged or turbocharged

than get headers and a 3"

....

i laready said that alex.. lol.. but i guess atleast i'm not the only crazy one..

I had a 2.5" on mine and can easily tell a difference compared to stock. I could feel a loss in low-end but not enough for me to care. If I've heard of supercharged guys feeling a loss in low-end with a 3", you know N/A is gonna have a loss too.

but 3" on a s/c the loss is compromised for when you have the less restricted flow and produce a better mid to high end

_________________

Yeah, because I have headers back to a 3" exhaust and I have no loss at all.

i got a 2000 gp gt... all stock but i want to make it sexy and fast. But i got a very tight budget ($0-0.01) So i try to make it look nice with what i got. Unfortunatly, speed comes latr

I emailed ZZP to get a good answer. And trust these guys. They are right on the target. Everyone here at GPONA helps so much, and they know so much. This is what I got from Turbo Tim @ ZZP.

I first told him I had an Intake, and the front PLOG

He wrote

If your car is a GT, then I would recommend:



GT1 cam (+25whp) or ER rockers (+10whp)

High velocity throttlebody (+5hp)

Underdrive water pump pulley (+4hp)

HV3 insert (+25hp)

Powerlog (+5hp)

Ported rear manifold (+5hp)

ZZP Bolt in 2.5
