Hey guys i installed my B & M STS about a month ago.. its great and all but when i throw it in hear, it makes a nose like its hitting something, not grinding. Just like a ding sound. Nuetral does the same thing when i go left-right with it... Is this normal? Maybe im just paranoid. Thanks!

 

Are you supposed to dent the cat heat shield with the B&M? If so maybe it needs some more deforming.

 

I took of my heat shield. I have a high flo cat on there, the stock one wouldnt fit.

 

check your high flow cat for any dents or marks cuz you are probably hitting that with your STS.
