I'm gettin a 3in exhaust done tomorrow. DO i really need a resinator or Cat?????????? i know how to do the resistor mod to the O2 sensor, my main question is will it hurt not to have these? i mean is there any danger to my engine. i'm putting on the turbo kit soon, that is why i'm goin 3in. please give me feedback
tks

i'm going from the dp back!!!!!

No danger in taking out the cat or not having a resonator.

It's gonna be loud NA.
You're gonna have a CEL. (without the resistor mod)
It's illegal.
It reeks.

i'm getting this done tomorrow, should i just have them flange it to the stock cat and just buy a high flow one later (order tues)? what should i use as a resonator(glasspack)???????? will i still need the resistor mod with a high flow cat????

what is the stock size of the 420A down pipe???? and what is the size of the cat???? i just was looking for a catco high flow cat and it listed it as a 2in. is that true? alittle help plz

The stock exhaust is 2"

ok then need some advice...should I:
1)wait for my turbo kit (2.5 in dp) to do the exhaust

2)have them do 3in cat back(is cat only 2in???)then just put in a 2.5in high flow when i install the turbo

3)just jump off this bridge i'm looking down from??????haha

please help out guys...i'm tired of the stock crap and i already bought the 3in muffler(Blitz nur-spec)

Which turbo kit are you getting? The HRC kit uses the bottom half of the stock dp.

you gotta be kidding me...originally i wanted the star kit but everybody who sells them is having problems getting the intercooler in stock. that is why i was going to go HRC. guess i need to stop and think this whole thing out again. this sux....anybody have 3in with either kit let me know how/what you did it with..tks
