V8 Quicksilver Cat Replacements

[acollin5]

Quick question - I tried searching to see if this question has been discussed before so apologies if it has - I didn't find it. Has anyone fitted the Quicksilver cat replacement pipes only to their car. How did it change the sound? Does it register any warning lights?

Thnx

Andy

Are your sport cats, primary or secondary cat replacements. I understand that later Vantages have 4 cats instead of 2. I have a N420 with 4 cats and a rear sports box which gives a deeper note than standard which I love but was hoping to benefit from the driveability/performance improvement which comes from sports cats or decat pipes without necessarily making the sound level ridiculous. I prefer the deeper burble type of noise like a Corvette. Some vids on You Tube are insanely loud.
