KH 200 cel cats

Today I had the Ken Harrison 200 cats from Enjuku racing installed on my 08 Vantage. My car has the quicksilver sport exhaust. It is a bit loud but I'm hoping that with the addition of an X pipe that it will tone it down a bit. You can definitely feel the difference in the power. So next will be an X pipe then a tune. The muffler shop in St. Augustine is going to make a custom X pipe for it.
These cars sure are built good and you notice it the more you work on them.

Where did you buy the cats and how much were they? I am interested in getting some cats too.

My quicksilver sports is way too quite so this might be the fix for me!

As an update. Had Rick's muffler shop install the X pipe today. With the KH 200 cel cats, the X pipe, and the Quick Silver sport exhaust it sounds great. The X pipe did quiet it down some but such a glorious sound. If the headers ever go on sale I might just have to try that also, but for now couldn't be happier.

I have the AC secondary cat delete and center section x-pipe. Below 3500 rpm's there isn't much difference but above that it's really nice.

More exotic sounding across the range, but as said it is just what I was hoping for when pushing it a bit. It is louder but not too loud. Just better. Supposedly there is a HP bump but I can't really tell.

I have also added 200 cell cats & found it to loud, its fine on light & mid throttle, but at full throttle much too loud,

Some pops and crackles but nowhere near as much as my 911 with the factory sport exhaust. I'm reality happy with the way the Aston sounds now.

On my car with no secondary cats and mid section x-pipe there are no crackles that I have noticed. And definitely not too loud.

Hmmm, I love the sound of the backfires & crackles,


just want to turn the volume down a notch, don't want to add the x pipe & they are gone,


do you have sound clip
