3" or 2.5"

**ChdMcD** · 04-07-2010

hey im just wondering is it worth it to get the 3" zzp downpipe over the 2.5". i dont think it should make to much of diff but thought id get some input

**whiney** · 04-07-2010

Do you have a gt or gtp? 3" is going to be your better choice regardless.

**ChdMcD** · 04-07-2010

gtp dont plan on heavily modding just going to 3.5 pulley. just wondering if it worth.

**whiney** · 04-07-2010

what all other mods do you have?

**TorqueAutoMotiv** · 04-07-2010

3" dp all the way
id look at headers even if you arent modding that far

x2 for a little bit more get the speed daddy headers and have much better flow. You want to get every degree of heat out of these motors that you can.

If you're dropping pulleys you need the 3". 2.5 won't cut it.

2.5" won't cut it unless that is the ONLY mod you did to the car...EVER.

the only thing i mite do is drop to 3.5 pulley dont plan on moding to much at all gonna keep her pretty much stock. its got cai- considering buying new zzp man its nice- but thats pretty much it. its quick enough stock for me. nobody has beat me yet and its stock

3'' or headers, its not even a question. it will compliment the intake

**ChdMcD** · 04-09-2010

isnt the 2.5" goona keep my torque lower on the charts. im gonna have zzp high flow 2.5"dp, 3.5 pulley, tr6 plugs, zzp cai, undecided on which headers to get opinions? and same story for pcm thinking zzp tho?? this set up i shouldnt see kr and be pretty reliable rite?

Listen to what these guys are saying...3" down pipe OR for a little bit more get the speed daddy headers and have more flow.

**whiney** · 04-09-2010

Speed daddy headers, and if it was me i'd go with an intense or overkilll pcm or a custom tune if you can find someone to do it for you. Don't go zzp.
