I rescentley installed a Magnaflow Magna Pack Cat back on my 07 Gt.
This is a bolt on sytem and it is fastened tightly. It sounds awesome when I am just cruising and really kicks in when i step on it. I have noticed a slight whistle around a 2500rpm. It sounds as if it coming from the h-pipe where the cats connect to the 2.5 magna flow pipes. Anyone know of any ways to seal that up a little tighter so it stops the whistle?
