Downpipe options
 

I recently purchased a 2008 SS automatic and am looking to upgrade to an off road down pipe and am just curious which company is preferred for performance and reliability with censor issues. Also looking to upgrade the intercooler and hot piping if there's any pro's and con's to certain companies. Could really help to get some info on these parts.

Hahn is the only company that makes a dp specifically for he automatic....there ends up being a difference in length if a regular dp is used with an auto tranny....not sure why. Any of the cobalt parts will fit the hhr. I don't recommend hahn....their customer service sucks and they are way over priced. Zzp, dejon, hahn, treadstone, mpx, badmab all make downpipes. All but dejon and badmab make intercoolers as do genuine sabb and werks. All but mpx and badmab make charge piping.

If you are worried about cel's w/ the downpipe id stay away from the badmab cause it doesn't have an angled o2 bung whereas the others do....that will help prevent the cel's.

I have a 3" catless Stainless steel DP from Clear image for sale. also already has a bung for wideband. $270 shipped

just a little FYI

haha i forgot all about cia they kinda fell off the map for a while. they are starting to get back into it with the release of the air intake kit for the hhr ss

I just bought a Bad-Mab DP and I also got a Vibrant Defouler from Modern Performance to go with it. I will see how it goes once I install it hopefully within the next few weeks.

I am looking at purchasing the Bad-mab did it work well for you? I have an automatic and am concerned about the fitment but can't find ANYTHING here on the forums about the BadMab and autos here on the forum.

TurboXS is also producing downpipes.

isnt ZZP making ds for the auto now?

I own a zzp, CIA and Hahn downpipe
Personally my fav is CIA version
Least is my Hahn which I swear by feel of pipe is crush bent lol

ZZP makes'em for Auto's....I have one on mine...fits perfect. Not to short (like alot of people talk about). Just have to specify when ordered that it's for an Automatic
