yes, so dont do it, they are no gains from it
08-18-2010
ok was just wondering cause i see alot of ppl without cats. then why do they sell dp's without cats?
08-18-2010
No, it won't. It'll work on his car just fine. Those are only on the '01+ cars that require the cat to be there because of the fueling tables in the PCM. There are always gains from getting rid of a converter...question is...is it worth the ticket if your caught without one?Originally Posted by Fivefingerdeathpunch
Because it also makes the car sound tons better...and some people want all the restrictions gone in the exhaust system to get every bit of power possible. Plus, they are WAY cheaper.

ok thanks for the info. their is a free flow cat for 40 bucks that looks like a cat so im not worried bout tickets lol.
08-18-2010
Frozen Boost converters. Look into those.

That is the one i was looking at lol. but was wondering if it was safe to use it because of the sensor after it.
08-19-2010
Safe yes...it won't do anything but trip a SES light for low efficiency on the rear catalyst.

ok thank u

If it was an '01+ car however...it would make your fuel trims go all crazy.

I nuked the cat on both the '01 and the '02, and waited to see how long before they tripped a SES light before turning off reporting via HP Tuners... The '02 went 2+ months, and after a pully swap and headers I had to retune obviously, so I turned it off... The '01 set the code in less than 3 miles after swapping to a catless DP. Beats the hell outta me.

i dont have a cat in my 02
08-20-2010
How 'bout under it?
08-26-2010
my car is an 02 with no cat and i havnt thrown a code
08-27-2010
I replaced my dp with a high flow cat and my ses light is always on b/c of it. Mine was pritty cheap tho I got a deal on it. Was only 200 bucks which is cheap in my book.

I bought an 02 simulator and havent had the SES light come on.
I even passed emissions with it

you know i recently put my catted zzp dp back on my fuel trims were reducing upto -21% LTFT, STFT. now its around -10%LTFT and enriches in STFT but the car still doesnt pick up like it used to it feels like its bucking and little to no power.
but at first it ran amazing Catless nice rasp and was quiet top end. Trying to see if ZZP will retune my pcm for proper trims now that everything is back in order and this is on a 06 base model.
