here are a couple of video clips of the corsa sport that i installed with the "whine" noise. the first is an idle clip where it is normal and you cant hear the whine. the second is a WOT run where you can hear it above 4k. i called corsa about this and they said it was the tip, but i removed it and its still there. the clips were before i took off the tip. tell me what u think this is. is it the muffler?

Try to plug the hole on the bottom of the muffler and go drive it again!!

 

Strange. Sounds awesome at idle but the whine is annoying isn't it?

 

its more than annoying, its startin to dive me . i hope corsa will do whatever it takes to resolve it.

 

Try and plug the hole, see what happens.

 

what can i plug it with that i can take back out?
by the way whoever it was that told me to weld the tip on must not have ever tried to take theirs off. it took me and another guy over an hour with a torch to get it off. the clamp made just a small enough crease that it wouldnt come off.

 

Throw some tape over it or something. Just to cover it ya know. See if the whine goes away.


I wont weld my tip on.

 

Side note, how do you like the the L76. Does she scoot?

 

Seconded, I'm trying to debate whether to get an 2008 Vmax Extended Cab or a 2008 5.3L Regular cab.

 

talked with Corsa again today and they were very willing to please me. they are sending me a complet new kit and a "little care package" for my trouble. as far as the noise they said they are stumped and not sure what could be doing it, as they have never had this problem before. For those interested in the L76, all i can say is i havent driven a new 5.3 to compare but the L76 seems to have alot of potential. mine is stock for now and was slightly dissapointed, dont get me wrong it runs strong but i was expecting more. it is in need of a tune BADLY. it pulls pretty hard in the higher rpm's.i know this doesnt help you guys much but i havent played with it enough to tell you what it can do.
