Test Pipe on 2g

I am hitting up my muffler shop today, because I got my 2.5 DP on, and I am wanting to get rid of my cat.

So, can we put test pipes in our 2g without tripping off a CEL? Or should I get a high flow-3" cat instead.

I would prefer a test pipe, as it would save me $100. But, that is why I am asking.

Opinons? Thoughts? Pros? Cons?

Thanks,
Nathan

Just make sure that you reattach the O2 ground strap to a proper ground point. Your CEL will come on quite often if you didn't find a good grounding point for your O2 strap...

all its for is to let your computer know if you are filtering your exhaust or not - there is a sensor before the cat and one just after - the computer compares the results from both sensors and they aren't a certain amount different then it sets off an alarm and your cel light goes on

the bad effects of not using a cat are what you should be more worried about - it really is not a very good thing to go without a cat but i don't have one its bad i know blah blah blah.......

and the link should be good for a while i just got two new servers and as soon as they are done being setup they will all be mirroring each other

Ok! i took off my cat yesterday and put a replacement pipe on. This pipe was not a straight pipe..it has some resonator material around the outside...my car is not any louder...and the turbo spoons up a heck of a lot quicker! i have a boost gauge so i do have an accurate reading.

 

[psyjoniz]

awesome! i am still envious of boost as i have none

 

[koreanpersuasio]

oo..they sell turbo kits on ebay..

i just put a test pipe on and it made my car a HELLUVA lot louder......it sounds too mean!

 

[SpoOLxExO]

it worked great.

and just as i thought, becauseof the light, the car likes boost!

18 psi pig rich, but it loves it!

thanks again

i do believe you said it's not a straight pipe...but instead has some resonator material inside....prolly that combined with the fact you still have your stock muffler makes it not much louder. all i know is that mine ROARS.
