i like... debating between this and Hahn's 3" catless dp. yours is a few $ cheaper. does your product come with new gaskets?

 

Well I have a question, I installed a Bad-Mab DP with the vibrant defouler a few months ago and all was fine until today, I threw a code. I have put about 600-700 miles on it since I installed the downpipe. Any suggestions?

 

from what i have read, the best option seems to be to get a tune w/ the 420 code disabled. if not, you are stuck having to reset the ecu everytime a cel comes on. for some reason catless downpipes and our cars dont get along too well. lol. hope this helps.

 

Thanks any idea how much would someone charge for a tune to just turn off the 420 code? I don't have an extra $400 for a full tune.

 

So where i live i dont need emissions i was wondering if i got a catless dp but didnt tune it would it be worth it sorry if this seems stupid ive driven trucks most of my life and never learned anything about tuning cars

 

If you already have an HP Tune, then get the cat less down pipe.. Do you still need a retune? What else can be tuned for after the swap if you already have a tune?

 

Im gonna buy a downpipe for my 2010 cobalt ss turbo, and my buddy has a bad downpipe on his 06 supercharged,,, will my downpipe fit his car?

 

^ i dont think so

 

Just for info, when i put my catless downpipe,my car have approx 10-15 more hp with trifecta tune.

 

I've done some testing of different DPs...
DP testing, the Ruthless Pursuit of Power - Chevy HHR Network

 

nope

 

anything

 

I don't think any come with new gaskets.

I got a catted hahn and it was amazing looking. I don't drive in winter, so it still looks new.

 

my turbo xs came with new gaskets...its catted, if anyone wants to trade for a catless

 

^ If you're sensitive to smells don't do that swap as it won't be worth it haha.

 

i just wanna have the tractor sound...lol...my catted one with muffler delete sounds great though.

 

Gut your cat and cut the factory resonator off.

 

true...good thinking....lol

 

lol or you could get the turboxs one. it's great with no hassle. lol

 

Quick question(from a noob). I'm hopefully getting tuned this saturday a couple hrs away from my location and was going to install my zzp catless dp but upon installation realized I was an idiot and didn't order any o2 bung for the rear o2 sensor. I read alot about how the rear sensor just detects the cat efficiency and won't make the car run rich or lean with out it, is that correct? I would like to install the dp, unplug the rear sensor(expecting cel), and possibly have a shop do the muffler delete option before getting tuned in a few days. Basically, if I unplug the rear o2 sensor, is that going to **** up my car driving 2 hours without it before getting tuned? Thanks.

 

Seem to remember reading something about 07's having a problem with the rear o2 being deleted.

If I get an aftermarket catless downpipe will I need to get a tune? Or do anything to my car?
