Has anyone put the KBD Targa mufflers on their 78-82? If so how do they sound? where there any performance gains? If anyone has an audio clip I would love to hear it. I was also thinkin of the super turbos, I had a pair on my chevelle before I put glass packs on it (I hated them after 3 months). I read in Ecklers where corvette customers say the KBD's make your vette sound like a vette is that so? Thanks guys you are a real wealth of knowlege.
