Will it be more responsive on the 2.5" round the streets compered to the bigger? But Will a 3" make more power? | 2.5" exhaust on rb30det maxed out at 340whp (told to come back with bigger exhaust), what car made 600hp with a 2.5" exhaust?
If you are aiming for 200wkw on a GT28 I would highly reccomend 3" (straight as possible) exhaust..
What ca18det makes a true 550atw figure in the country? LOL
You want as least possible restriction in the exhaust as possible for Forced Induction unless you have a lot of money to spend on extensive R&D |
Couldn't tell you mate, I have only been told this, and then going to 3" went slower.. Don't quote me on this.
Everything i posted was more of a question, not a statement luke.
Sounds like i have been told the same as bumped-EG and got told..
Its not "NEEDED" for our setups, BUT.. if you want more power and less money in you pocket Ect Ect go to a 3"
ONE more question.
AS far as plumbing pipe back for the gate, further down is better? and would i go for a 2.5" for that?? maybe create more volocity pushing it back into the exhaust?
