im looking to get a downpipe for my 09 cobalt ss i found this one on ebay Cobalt SS/TC Turbo LNF Stainless Steel 3 inch Downpipe | eBay ..... i was just curious if anyone used this one and if not what other one should i get i wanted a catted one because of emission purposes but if its easy enough to take off during inspection time i have no problem removing it can some one please let me know which one to get cuz im new to chevy and i read the sticky but it didnt say which one is better

 

Bad mab is cheap but a catless dp is a catless dp... you will throw a code with it most likely... To avoid the code you can tune the car and turn the code off or get a plug defouler and see if that will keep you from throwing it. The code for the back O2 sensor won't throw you into limp mode or anything it just tells you that your cat isn't working

 

I am currently selling a zzp spun metal fatted dp... Pm me for details or check out the fs thread.

 

Yeah bad-mab is cheaper then the comp. doesn't mean it sucks by any means

People that have it love it

Other people say that it does rust up faster then others because of it not being 304 stainless but that doesn't effect performance any

 

MPx FTMFW

 

It's just surface rust and it has no effect on performance. It wont rust all the way through... err or it shouldn't rather, I'm sure there are situations where corrosion has taken out even 304 ss

 

Right here. Quality is fantastic.

 

plus they are in texas so win win

 

i love my bad-mab... pretty good power gain.. esp when tuned and the sound is awesome

 

I have Bad-Mab, I recommend it.

 

how hard is it to install and or remove the downpipe for emissions purposes new york state is tough with inspections if the cel is on it wont pass inspection and if i remove it clear the code and go get my inspection will it pass? if anyone knows ny state laws its a toss up between the bad-mab or mpx either one around the same price

 

im sorry for the double post but if i have the gms1 will the car learn down the downpipe with it or did it get rid of the learn down?

 

I went bad-mab, only comes catless. At 159 bucks to my door you cant beat it. It does the exact same thing as all the other brands except brad sells them for a reasonable price.

 

Love my CIA stainless catless, shiny penny for a new one though


7 bolts and 2 new gaskets every time you reinstall for emissions. The stock DP is kinda a pain to remove and install, so if you have to do emissions I'd suggest getting something with a cat in it.

GMS1 removes learn down.

 

ZZP here lol love it amazing piece.

 

It takes about 30 minutes from jack up to jack down.

 

Unless some ******* crossthreads the nut all the way onto the stud. It took me 30 minutes just to get the one damn nut off.

 

BadMab currently. Great piece. Also had ZZP catless at one point. Also a great piece.

 

yea get the badmad dp i just got one and they are super fast shipping and they sound beastly lol

 

one is not better than the other! They are all 3 inch pipe and thats it. yeah they are made out of a little differant metal but thats not gonna effect the pipes performace

 

ok so if i get the bad mab and my check engine light goes on if i clear it take the pipe out take it for inspection will it still pass or should i just get the anti foulers? and do you think one or 2 of those??? Last question and im finished how loud is this going to be with muffler delete? cuz i have that now and i dont want it to be crazy loud i guess i could have the muffler welded back on if anything thanks for all the advice

 

IMO you'll want a muffler if you like it quiet while cruising.

 

I think its loud enought at WOT with the catless downpipe, i wouldnt personaly run a muffler delete, but everyone have their own preference...

 

zzp the flex joint is bigger and has a piece already made for the o2 so no codes, but does cost more . and to be honest you really don't have to change the gaskets .

 

Ive run a 3 inch catless and straight pipe and it was too loud... now I have a borla x1 and it sounds good.
