any input here would be great.
what would give more hp the racing beat full 3" exhaust system or the 2.5" racing beat down pipe and pre silencer and a racing beat cat back used, off of the full 3" exhaust system.

 

N/A or TII?

 

good point.. tII i guess that info would help

 

im not really sure about a TII......


but for my N/A i got the racing beat headers and presilencer and then took the car to a shop and had them put on 2.5" pipe all the way back and WOW.....HUGE POWER GAINS, but also major volume increase. it is LOUD

 

Well, bigger diameter = less back pressure. Less back pressure = more power from the turbo. Just make sure you have plenty of fuel and a good bosst gauge. Boost creep is a bitch.

 

bigger all the way or just at the end. I heard somewhere that if u start smaller and go bigger towards the end it will genaerate more hp. any truth there ya think?
