exhaust idea need opinons?

[96TalonAWD]

I got a 2.5" cat back no money for the 3" and was thinking in getting a 3" DP and test pipe no emissions in FL will that create some kins os boost creep?

 

[candela]

yes...

you want the most flow near the end of the exhaust...yours will get turbulent when it hits the reduction at the C-B and will most likely be even more restictive than if the whole thing were 2.25 in even.
I don't foresee it causing boost creep just because of the neckdown, because creep comes from too much exhaust not being able to flow through the wastegate...you will still have the same flow through the wastegate as you would with a smaller DP however, you will have less efficient flow through the rest of the exhaust with the exhaust hitting that reduction after it has cooled down and lost some of its velocity and becoming turbulent, but the 3" in itself could cause creep if you crank the boost up and manage to squeeze the exhaust out through the straw at the end...

i am thinking in getting the 2.5 DP from phantom roadworks, any experiences with this one?

 

[nine5raptor]

i've just heard good things about it...i was thinking of getting that one too, or building my own. depends if I can get ahold of a welder or not.

no one has been able to get in touch with phantom roadworks for months now.

i already buy the a 2.5" DP that extends 3" after flex this will help boost response even if i am running a t-25 right?

 

[GSX_RCR]

I don't think anyone can boost creep with the t-25.

i heard the Phantom downpipe blows goats. Too small of a flex section, doesn't fit right at all. i was gunna order it but not after what ive read about it
