We just finished up our stainless steel 3" downpipe on our cobalt ss/tc. We cnc'd both flanges in house for precise fitment with the stock components. It also features a flex section to allow for engine movement and daily abuse. The downpipe removes the restrictive factory catalytic converters.

Morgan will be putting the car on the dyno later today, look for those results here.

features:

-direct replacement no modifications required
-removes catalytic converters
-made in the USA
-madrel bent for free flow
-simple to install
-dyno results soon to follow

Introductory Special $299 shipped for cobaltss.net members.

notes:
*due to the removal of the catalytic converter, this downpipe is for off road use only, and not legal for use on US roadways.*

 

Looks good. What is it going to cost?

 

w000t way to go guys and getting the ball rolling quicking it seems the ss/tc is goiong to be huge in the aftermarket as far as gms go

 

What about CEL?

 

bumer... every day I feel like my lsj is being tarnished... Crys to himself! lol

 

Wow, that is very nice, but what about getting some DTC codes. Is there a tune to dissable the rear O2 sensor?

 

tuning is still verrrrrryyyy limited....HP Tuners is working on the next update to be able to tune the TC tho which should allow the rear O2 sensor to be disabled.

 

Not needed...
Look closely at the pictures, the rear O2 bung is extended to avoid setting off the CEL associated with the cat.

 

precisely.

we are still doing some testing, but we havent had any codes yet. when the hp tuner software becomes available there will be a lot more we can do with this car, including our gt3076r turbo upgrade.

introductory pricing on these will be $299 shipped.

 

Theres already tuning using the PPC module.

 

Very nice guys. Just curious, do you have any plans on making a downpipe w/ a cat?

Parts for the SS S/C would be nice as well...

 

lol, Us SC guys are old news man!

 

correct me if I'm wrong but the PPC handheld tuner isnt a user adjustable tuning solution, it simply flashes a preprogrammed map. we would need something we can tune for our exact kit.

 

quoted from Hahn

"It's plug and go, with one highly developed program. End-user tuning is not supported at this time. The Bosch DI controller is a very exotic and hugely sensitive system that's not yet equipped with end-user friendly options. So, we take all the stumbling and guesswork out of it."

 

can't wait to see some numbers

 

++++1

 

will this bolt up to the hahn 3 in catback?

 

^^^ good question

because i am getting the hahn 3 inch catback

 

they said its meant to bolt up to the stock parts of the cobalts. so i dont see why it wouldnt

 

Sound Clippppp!!!!!

 

looks great, can't wait to see some #

x2!!

 

Me too.. im wondering if i should just get the 3 in. inlet or the Tc inlet.. i dotn know what the difference is???

 

We have like 50 downpipes man , and enuff aftermarket for a wise person to build 400+ hp car now

Nice welds , that looks like a nice quality piece .

 

nvm I just seen the cat is gone... which is not legal in the US

 

so your point is....
