Catted Hi-Flow DP N55...?

NORAGRETS · 12-28-2012, 03:58 PM

Anyone have good results with a hi-flow catted DP for an N55...? Did it throw any codes?

You won't pass a sniffer test with a hiflow cat. Why do you want one?

NORAGRETS · 12-28-2012, 04:54 PM

not worried about the sniffer test or inspection at all just dont want to throw codes with catless

get a JB4 and you won't have to worry about codes

NORAGRETS · 12-28-2012, 05:31 PM

can the dealer detect the DP fix or would I have to uninstall every time I bring it in?

There is no DP fix for the N55.

JB4 is your best bet, might as well go ISO at this point, and then just activate Auto Clear, or clear the codes yourself.

The Dealership can tell if you have any kind of aftermarket DP, catted or not.

Im in a good enough relationship with my dealer that they wont care about aftermarket bolt on DP etc. but are really sticklers for anything software related...

NORAGRETS · 12-28-2012, 05:53 PM

and CEL lights....

Well I can't speak on behalf of catted DP's, but I have the AR Catless and it throws a code at least every other day, but I have auto clear on, so I never see them.

If you are in good with them, they should understand that, but then again, it's all what you feel like chancing.

I am in very good with my dealer here in Germany, they love the sound of the car, but I am sure if it messed something up, and it was my fault, I'd most likely pay for it.

I've been looking for the answer to this too. I want a catted down pipes with the soul intention to not throw any codes. I do not want to have to do a piggy back tune or anything else. My dealer is just fine with bolt-ons, but doing anything that throws CEL codes or anything software related is a no-go.

Pretty much found the answer to the question. Took some time on google search though. I found that even with a catted down pipe a CEL code will be thrown in most if not all cases depending on the brand of catted down pipe. Looks like I wont be messing with any down pipes until my warranty is out.

Im not too worried about throwing codes but dont catless DPs make the exahust much louder as well as SMELL bad?

NORAGRETS · 03-12-2013, 10:25 PM

if by bad you mean delicious and by loud you mean amazing, then yes

Good plan

Grayson · 03-13-2013, 01:28 AM

Don't be fooled, catless smells and smokes like crazy and not in a good way. JB4's, COBB, they all auto clear the CEL so you'll never know its on.

Focusedintntions · 03-13-2013, 09:31 AM

I have a catted Vishnu DP on my n55...and without the can-tool from BGS it'll throw a cell.....when I was researching I found that all of them will throw a cel eventually.

does it smoke and smell until you break it in or soot it up? or just continuous smoke and smell?

Mine always did, even after a few thousand miles. Not sure though, maybe after 10K+ miles it might be different.
