so i've done some searching on this product and i'm seeing that some people are having problems with it. i'm planing on doing the 1 3/4 header and 2.5'' dp with high flow cat. is anyone getting codes with this setup? thanks!

 

never had one problem....

 

MUWAAHHHAHAHAHHAHHAHHAHHA!

 

well thats good to hear, i plan on ordering it here this week. i have the gmpp exhaust sitting in my room now.

huh?

 

I love mine. Never had a problem.

 

Just put mine on yesterday, love it so far.

 

What problems? And get the 3" downpipe

 

the only "problems" with the ZZP, is people not tightening it up and having leaks (easy fixed)
or people throwing cat codes due to the high flow cat. (expect this with EVERY aftermarket downpipe)

 

My ZZP dp hasn't thrown a code...YET... but what a purty piece of pipe.

 

Yeah it is defintely a great upgrade. I would highly recommend it.

As an0malous said you will throw a code because of the high flow cat, but they can be deleted with a HP tune.

 

i threw the p0420 code. getting it deleted tomorrow. love this setup though.

 

i had 3 codes when i had it installed got it hptuners and it went away ..havent had a code since ...

 

you could probably delete the code if you have an interceptor gauge, couldn't you?

 

I have the same code with vibrant header and downpipe

deleted once and it came back on in 5min of

Dont know what to do now
Is there like a fuse or somthing that i can plug out so no more CEL ?

 

Yes, you can. But when you drive around for about 10 miles it'll come back. Only reason I'm really worried about it is because I need to get inspected by Friday and it will not pass with this CEL.

 

What can you guys tell about the gains

ZZP states that gains between 15-40 HP can be reached depending on mods.

Personally, I highly doubt that anything above 25HP is possible, but maybe someone can give some details on what they (think) they gained. Most importantly whether the car accelerates noticeably faster after installation !

Anyone
The floor is open

.

 

no way 40hp lollllzzzz

more like 10whp

I defintaely noticed some gains when I installed mine. I dynod at 269whp with Stage 2, 2.9, ZZP midlength and Downpipe combo, AEM Intake, GMPP Exhaust (recently switched to DC Sports)

 

beware the header to dp flange bolts, they like to break and go flying into car windshields, oh and the flex pipes tend to leak as well. these notes are just based on experiences from people around me who use there products

 

i got a ZZP header/dp slapped on a catback and my trap speed went from 101 to 108..

 

im sorry, i just couldnt help myself when cole said that he never had a problem. Its just funny cause he DID have a problem but it was with HIM! HAHA. check the link!

and i did have a problem. the bolts snapped that connect the header to the downpipe. and i dont wanna hear "They now have upgraded bolts" cause i got the upgraded bolts and they still snapped. If you get it, do yourself a favor and go out and get yourself some new bolts. dont listen to everyone else who says that they wont snap. save yourself a headache.

nah , the flex pipes are great, Luke's whistling flex pipe wasnt ZZP's. but he has since upgraded to a ZZP downpipe with no problems...

Go get it...and some new bolts!

 

^ retard. i had problems getting it on ... but after its on its gravy. dont listen to amateurs

 

I was thinking the same thing...install was a problem...but not major

 

so why is the install a pain in the ass?

 

because, installing a header in general is a pain.
