My TOTALLY rubber mounted Mallory Comp 140 is so loud now that I can't even hear the exhaust on my car anymore so I'm thinking it's on it's way out. So I started shopping Summit and there is lots of choices but is there a standout among the brands? Aeromotive, Holley black 150, Magnaflow, Mallory, Edelbrock 160 etc, etc....is there any to stay away from?
