I put a Corsa Pro series dual rear exit cat back on my 2006 GMC rcsb and the left pipe will not stay put on the hanger. Within a day of retightening eveything on the system it starts sagging. I have gone through 4 times and re-adjusted the whole system, muffler to tips and it keeps doing the same thing. I have started in the rear and tightened towards the front, and vice versa. Is there anything I should try boefore fabbing my own brackets? Here's a pic of what it's doing... in the last pic, I rotated the pipe up, but as soon as I move, it falls back down, despite the clamp being tightened with an impact. Any input is appriciated...

 

i dont know, corsa usually has pretty high quality stuff

btw, when posting pics on internet usually good idea to edit out your license plate

 

Are you sure! you put them right? i mean did you get any other mods to your truck? like drop rear ?
corsa's got one of the best exhaust system in the market.
love my corsa!!

 

What exactly is loosening, the clamp? Maybe some loc-tite or a new clamp or clamp bolt will help?

 

The last piece of pipe is rotating down (and out a little) at the joint next to the spare tire, even through the clamp is lined up 90 degrees from the slit and tightened with an impact. I guess trading that clamp out with one of the other ones is tomorrow's idea...

As far as my license plate, I'm more worried about people around me driving having it than the internet. If you want I'll post up my address and phone # too, I got nothing to hide.

 

I'd give Corsa a call and describe the problem your having. They have a good tech department and can usually lend some good advice

 

I dont know if you can or not, but it would be a quick fix to weld a 1" bead along the joint where the clamp is just to hold it good. but a new clamp would be the best thing I guess. The dynomax clamps are the

 

Why is that exactly? People see my license plate all day as I drive around...what difference does it make if someone in another state sees a picture of it?

 

EDIT: repost

 

as i was told when i first joined the site, someone that has your license plate number can either:

a. see that you have a modified vehicle with things worth taking off and stealing -or-

b. use your license plate number to steal your identity by hacking to get ph #s addresses ss#s etc
