hmm i still dont have my header back from zzp.... im getting a bit disappointed.

Anyone dyno their setup yet? I did...lost 3ft/lbs and gained 4hp, but it shifted the powerband to the left and fattened it up towards redline, so it feels much quicker. I also had a slipping clutch on the dyno this time around, and last time I was on the rollers I didn't. That may have contributed to the loss in tq.

if your primarys were too big then you would lose tq also... just a thought

from mine i get kind of a metallic rattle at idle or when the engine is under load
sometimes heat makes it go away but it sounds kinda poopy when i get on it but not floor it. sounds to be coming from actually inside the header or dp...somewhere in the exhaust.

the best way i can describe it is a cross between a metallic rattle or tick and an exhaust leak.

i suppose ill have to get under there and check it out

anyone else noticing this?

sick06cobalt

Usually a rattle is the heat shield and you can remove it to fix that. Sometimes it's the cat, which is under warranty but it's rare.

nice shifting lol I kinda hear what you mean....did you check the heat shields?? I had 2....I took the one from the block to the header off, and kept the one under the header on there...no issues so far....

ColeJJones

sounds like the heat shield

sick06cobalt

I knew it sounded like a leak.

sick06cobalt

yeah it was a HUGE one lol

I have a leak as well now on mine, but I think I have the same problem as sick06cobalt in that something is not tightened properly. I am going to be taking it back to Midas this morning and see what they find.

guys, whenever you put new exhaust parts or any other parts, you should always re-tighten after a few days of driving.

hmmm how many miles do the both of you have on these items so far?? maybe this is something we should all keep an eye on if it's happening to a bunch of people...

DoubleLP

Nah....it is just like D4u2s0t said in that it probably just needs to be retightened. Kind of hard for me to do it when it is -25C outside and snow everywhere.

Co|3aLt $$

lol. nah - just get some good gloves!

D4u2s0t

yea, cold makes it suck! i'm going to double check mine again tomorrow or over the weekend.

DoubleLP

I am taking mine to Midas tomorrow morning, they were too busy today to get me in to look at it. I will have my update for you then! Maybe when it is on the lift I can get some good underbody pictures!

pjk91

got an inefficiency code today! awesome! will check for leaks this weekend but i really don't think that would throw this code.

it might just be a temporary thing due to temp and such.. if not just clear it and turn off your rear o2 sensor
