My car has all the stock exhuast back to the cat back!
I replaced the cat back with corsa'a sport exhuast... I recently had a problem arise with a small leak in the resonator. I t took a week the locate the problem as I had to wait for it to get louder to locate it. Here the front of the resonator had cracked giving the tell tail sign of soot on the pipe so I call Corsa who offered to replace the part no problem. Week later the leak is getting alot worse and the resonator arrives so i install it thinking that finally my car will no longer sound like a Honda... Drop the car to the ground jump in and hit the key just to find the leak is still there... Now I'm pissed!!! Jacked it back up thinking i missed something but to no availe... Here the resonator flopping around caused the front flex tube to rock about and break!!! Now it continues to get loader and louder and wondering if Corsa will do anything about this or not becuase it was there parts failure that cuased GM's part failure I think I am going to get F*cked becuase Corsa will blaim GM's stock part and GM will blaim Corsa's Aftermarket part so I am going to have to replace this myself!! And I'm sure this will not be cheap! I love the car but it's about trade in time and sorry to say Chevy will not be on my shopping list!

Any thoughts or similar problems? I need some help here!!!

 

Ok no bites on this thread. Some one any one I need to know what size the factory down pipe is so i can get this fixed, even hillbillied for right now so I can get to work!

 

i dont know about trading it in for an exhaust leak...fixing a leak is cheap..

do you know exactly where it is leaking from? like is there a hole? did you put the gasket on in between the flange? how about having it welded together?

 

the flex tube just below the 3 bolt flange at the manifold is cracked and under small amounts of load it will seperate and spuw the fummes out, aftermarket flex tube are avalible that can be welded into place of the factory one but i need to know the pipe size to order the correct one!

 

Perfect oppurtunity to buy a downpipe and header

triple posts!

Cheap fix...I dont think there is one unless you find a cheap used DP. Good luck

 

woops pressed button to many times.. lol

 

button smasher, it's what happens when you have dial up and a slow computer!! I post a WTB ad int the apropriate section but what i would really like to know is the Inside Diameter of the stock downpipe as a friend has mentioned the possibility of replacing just the flex section

 

go to a muffler shop and have them fab it for you...my new flex was 70 dollars installed

 

all exhuast shops around here won't touch it

 

why dont you put the stock exhuast back on and take it to the dealer and get your warranty to fix it? just play dumb

 

The reason the exhaust shops wont touch it is because the stock flex joint is part of the header flange . Do what u want , if u do that though ....make sure the flex joint is stainless and like the factory style and not a cheapie . Better yet would be one that is stainless , with the stainless braid over the outside . The stock DP is all kinds of sizes The hole in the flange is 3" , necks down to a 2 " ID as it goes in the flex joint , the OD in that area of the pipe is 2.5 , then necks up to 2.75 where it goes in the converter and exits the converter , then necks back down to 2.5 at the flange for the exhaust pipe .

If your car is under warranty and your stock DP still has the cat attached , and you dont wanna go with a aftermarket DP .....the dealer should cover this no questions asked . A few of my friends are techs at chevy dealers . When my stock flex joint broke , they all said the GM flex joints were cheap and they will replace them under warranty on . They said it was problem early on , on more than just Cobalts .

Your Corsa exhaust didnt break the flex joint , it was likely starting to fracture before you put the Corsa on . As long as the stock converter hasnt been removed or altered you should have no probs at the dealer .

 

37000 miles, Warrenty is all gone

 

would it be a good idea to up the flex to a 2.5 ID to match the pipe vs the 2 ID currently on the car?

 

not sure how this would be Corsa's fault.. I have a Corsa Sport cat-back and no problems.. Did u tighten the Torca clamps properly after u installed the exhaust.. your suppose to tighten to 60ftlbs and then run it a bit to allow the exhaust to expand and contract and then crank that bad boy down.. thats what corsa told me over the summer
