i put my test pipe on yesterday morning, it took me a little under 3 hours. kind of a lotof work, it went pretty smoothly though. i went to autozone to get the non-foulers b4 i put it on. they had the 18mm ones in stock, i drilled themout so the o2 sensor could fit and they bolted right on.
i definetly noticed a difference in performance and my car sounds GREAT! i havent got cel yet =)

 

my testpipe is on its way right now its scheduled to be here monday,

what tools doi need to install it?

on a scale of 1-10 how hard was it?

and would i be able to do it with just some friends?

 

yeah you should be able to do it with a couple friends, i did mine by myself lol there was a couple times where an extra hand couldnt of hurt.
id say from 1-10 it was about a 7 or 8 lol idk it was pretty tuff.
as far as tools.
a lot of different length socket extensions, 13mm and 17mm sockets
******universal joint socket extension! so you can maneuver the socket through some tight spots. i think without this it would of been a lot harder.

i have an HKS intake with a heat sheild, i took out my filter and the heat sheild to get to the cat easier and without taking the intake out i dont think it would have been possible to take out the cat.

 

ok im so pumped... did you notice a change in gas milage? or atleast a significant one?

my k&n 57i intake is coming on monday as well i may do both while im in there

did you use a do it yourself or instructions or anything like that?

 

one friend told me that it could possibly really drop my gas mileage

 

Keep in mind it's even more "tuff" to do if you have tiptronic/auto tranny. The tranny is much wider and makes the gap tightwhere you are looking up through/maneuvering your tools. Also fwiw AEB engines take much better to the non-fouler trick than ATW and AWM engines. Last I heard, Unitronics (BT chip) and APR are the only makers who offer a test pipe program that keeps your CEL off when the secondary 02 fault is stored.

Speaking of-
I have a stock cat off a 2000 1.8t w/ 80kish miles on it. If anyone wants it as a replacement or to gutt out to make your own test pipe, PM me.

 

well that sucks because mine is a tiptronic haha,

how do you know which engine you have?

 

Look here or here

97-99 1.8t = AEB
00 1.8t = ATW
01 1.8t = AWM

 

of course i have an AWM engine and i'm installing (fingers crossed) my testpipe this weekend....and i have a tip/auto tranny....i might have to recruit my dad to help me, he has way more patience with stubborn bolts and tight working space.

 

mines a 99.5 so im geussing i have an atw and also tiptronic so does any one have a diy or instructions on this?
