1500 miles... 2 sets of gaskets... 2 sets of upper DP bolts.. and now this...

ive never had a problem with ZZP until now.. anyone else have this problem?

 

I have a lot more than 1500 miles on my DP from them and never had a problem. Hopefully you can get it figured out.

 

nope but i did go through new bolts cause the pop out and gave me an exhaust leak

 

That same damn thing happened to my magnaflow exhaust, but it did last a good 10k before it did it.

 

probably should add.... yes.... that is a BOLT ON DP.. lol the other part is still on the header

 

I've never really heard anything good out of ZZP's exhaust stuff. The Grand Prix/Regal downpipes they used to sell had bad flex pipes that would actually restrict the exhaust after time. Turns out the "weaves" would come apart on the inside.

Zooomer is a stand up guy. I'm sure if you talk to him he'll work something out for you.

 

Yeah i know. thats why i'm not too worried. ive been a ZZP customer since early 2006.. spent a lot of money with them too. between the GP and SS im sure im over 5k spent with them. lol

for now i just have to run open header... oh well lol

 

AH, I didn't notice your sig

I've been a customer since '05 probably

 

had there 3 inch catless dp for 17k at least and never a problem

 

Wow that sucks. I just installed my ZZP midlength header/ dp combo and in less then 24 hours (only 20-30 miles of driving) 1 of the "Grade 9" Bolts snapped. I think it was a combo between 1 the "Grade 9" bolts are a cheap chinese knock off and 2 the bolts are 3/8" and the wholes in the flanges are 7/16" which has a lot of play and could cause the bolts to break. So I upgraded to some 7/16-14 X 2" Grade 8 Yellow Zinc plated bolts with 7/16 Hi-alloy lock washer, 7/16 SAE Thru-hard washers, and some top lock flange nuts. Im hoping the setup lasts longer then the stock set up. lol. Also I have a weird ass noise that I cant figure out. Good luck man, let us know how u make out.

late

 

this is part of the reason why my exhaust is staying stock...it's loud enough for me

 

looks like ur running a little rich...blame ur tuner

 

lol header and DP isnt for noise... im keeping the stock catback for that reason.. then just running a cutout when i race.



its just the base tune from zzp...

no other tuning has been done..

 

out the box tunes are alright..but there too general..not dialed in for ur car..i recommend getting retuned

 

Oh I know. If I replace part of the exhaust, the rest is being replaced along with it. It's just how I am.

 

ouch

 

I had that same tune, and lets just say I had a AFR in the 13's and 30 degrees of timing. I would suggest going and gettin a REAL tune ASAP.

later

 

ouch...

ur dp is hella carbed.

 

damn im bout to put mine on tomorrow, hope i dont have the same problems

 

they used the wrong type of flex pipe.

 

man... ive never had a problem with mine but i do need a new cat... mines fried...

 

I have had a ZZP 3 inch hi flow cat pipe for over a year with no problems (with that flex pipe type). It doesn't look like that pipe in the 1st post. What kind of pipe is that?

 

i have major problems with the zzp setup also. my header doesnt mate up to my downpipe correctly and i had to make my own gaskets that were thick to close the gap. also my bolts were no good, so i got some better ones and some better washers to make it fit. then i found my cat was no good, the 3 inch high flow. we dynoed my car after i put everything on and broke it in correctly and i lost hp. so i cut the damn thing out and it was solid black inside (yes i have a great tune) and if i turn it around there was stuff rolling inside it. so i too have had no luck with there products.

 

happened to me as well, after a month of driving.
