Hey real quick guys/gals,

Just to make sure I can install a catless DP, with out tuning, all its going to do is run a code. it wont change my fuel mix will it?

i will be getting the sensor turned off sometime after that but dont know when.

thanks,
Bill

 

Well, it depends...

If the Cat Over temp protection is on... it messes with something... its either timing or AFR (obviously) but i cant remember which..

 

what sensor detects that?

 

mines catless on stock dp you just need to turn the p0420 code off because the back o2 will read the same as the front.
don't get catless. it sounds like pure ass. catted cti dp on the way .

 

I never got a code from catless...I've since deleted the rear O2 sensor and put in a wideband. Still good.

 

this only half helps me, im already getting it and its 3inch. i am going to put a cut out in it. i dont think there is a space for the stock after cat O2 sensor just a wideband and the b4 cat narrow band

 

um wideband bung should be close to the first 02 sensor..if youre getting a cutout whats the point of catless

 

the question should be what is the point of having a cat if your having a cutout? Why spend the extra hundred bucks if you dont need to.. since its not even making it out the muffler anyway?

 

A cutout isn't open all the time....

 

Lol.. i sure hope not .

But i mean.. if your not worried about dumping it off to the side of your car... your probably not worried about spending 100 bucks on a cat.. lol

 

the only reason in my eyes for a cat is for E-Check. and im keeping my stock exhaust for that reason.... i bought my car new so i have a good handful of years b4 that happens.

also it is a bit difucult to install a cut out properly with a cat in the way

 

I'm just saying without a cat it's gonna sound like pure rice but to each their own.
Personally I can't stand to get on it till my new DP comes in lol..

 

Im catless and have no resonator, BUT I have a really REALLY quiet muffler on the car so it sounds nice and quiet. When I open the cutout its another story lol. But I love how it sounds at WOT with the cutout open

 

i went catless it sounds bad ass i actually felt a little difference. it will lower your boost and the check engine light will come on. my idle was a little fu**ed up it idled rough. i just got tuned for it last night and it fixed it

 

**** i love my catless dp and hahn exhaust...its amazing...but yea it does lean it out a bit...but not too much..u got a wb?..

 

yes i have a wideband. what kind of silly individual runs meth injection without a wideband?

 

hey killin howd you do on friday? diddnt get to see your 2nd pass.

 

no improvement, i bogged it and then waited for the ramp up of boost to hit.... sooo slow. i think im gonna get it changed to like start at 50% and ramp to 80%ish.

what does your first gear boost look like?

 

Ive had a catless since the 2nd week of owning the car, it doesnt sound like ass. And people need to get past the word RICE. this isnt 2005 anymore.

 

right now its set at 70% till 4750rpm then its 100% all the way up.

 

yeah see, when i get mine to hook its like waiting for my VTACK to switch over + turbo to spool.

 

i have mine set for 50 in the first cell up to 100 by the last. works like a charm and never break out the tires. perfect mix of boost and traction lmao.

 

it just sucks that i ran better stock 2 passes and driver fail

 

i have an xtc 2.5" catless downpipe for sale for $150 shipped. its only had around 200 miles on it. PM me if you are interested
