Do I need a 3" DP?
Hey guys,
I am wanting to buy a DP before starting the install.
What are todays best options?
I am thinking of a 3" DP and 3" back with a magnaflow.
Is it worth it using 3" or are there other bottle necks with the Greddy that cancel the benefits? (such as manifold etc)
Should I just go with 2.5"?
Thanks

right now it's a 2.5" to 2.75"
however my cat and catback is 2.25"
the muffler is also a dual exit with dual 2" outlets.
so I have absolutely the worst setup for flow, as it progressively gets smaller.
I did minor headwork and have shaved about 500RPM off my spoolup time.
I have a 3" on the way, so I'm excepting to see even better results. Hopefully something like 20rwhp at the same boost level.

that would be great success...
are you gonna do a write up on your head-work?
did you do it yourself or at a machine shop, i hear a lot of people saying they did it at home, but have no info to back it up, etc...
i have a spare motor, so i may want to experiment myself with some headwork
let me know if you did it yourself

thats impressive
