Not sure where to post this as there is no labeled "Exhaust" category.

Purchased my Touring system in 1/05. For the last year I have been chasing a vibration noise that came from under the rear of the truck at low speed cruising.
I get under there and shake and bump everything and do find the little XFR case skid makes noise and I take care of it thinking Aha! I only killed half of the noise but could not make the remainder happen unless I was driving.

In the past months its been getting louder and happening easier or more often. Finally I was out of the truck doing stuff while it idled in the driveway and could hear it.

It's the Corsa Touring muffler. I put gloves on and pushed it around checking the clamps and hangars and its the muffler. I shut the truck down and bumped it with my palm and could hear it rattling inside.

I contacted Corsa and one is on the way.

Thanks Corsa!

 

Glad they are taking care of you! Always heard good things about them, they are spendy for most tho.

Thanks, I remember thinking Spendy back then but having a nice Truck, Leather, XM Radio - Bose, Fine Company, and trying the Gibson and other Cat Backs just made me hate being in the truck.
Then I found out about the Corsa and the Chevy dealers at the time were putting them on Showroom customs and I sampled one.

I took a loss selling off the others but have no regrets. The performance and the in-cab comfort is as advertised.

 

no kidding???? my frikin joe gibbs does the same thing!!! i didnt think it was the acual muffler!! ill have to dig deaper and talk to corsa! maybe they can help me out!
This website is the best thing that has ever happened to idiot truck owners like me!!

 

Moved to the correct section for you.

 

Glad to hear they are taking care of you.

 

Thanks,

Got a tracking number today!

 

Got the new muffler on and its all good.
Boy it was a real PITA to get the old one off at the inlet, and to get the new one to take the tail pipe.
But that says a lot for the fit being as good as it gets. Nothing sloppy for sure.

It took some pulling, pushing, lifting, twisting and a few four letter words.

 

Good stuff. Corsa sure does have top notch stuff!
