Larini Cats on a Vantage

Larini Cats on a Vantage
I took the Larini Cats off my AMV8 because they threw codes P0430 and P0420(Cat efficiency below threshold) ever few hundred miles. I was told this may be due to the unexpected high volume of exhaust flow generated by the supercharger.
I can verify that they are worth 20RWHP and 10RWTQ on my car.
See my classified if anyone is interested. Posted around Feb 26th.

I removed the Larini cats and sold them but the car sounded too stock. Recently I've bought RSC cats. The 'growl' is back and I'm happy to report NO CODES. In my opinion, Larini's are poorly made and not worth buying unless you get them for a steal. I'd recommend RSC cats. You get a special discount for being a 6speed member. Getting the cats gets you a more aggressive, yet not annoying sound and you retain the increased bark at 4K RPM. It is the most restrictive (600 cell) part of the exhaust system and seems to me to be a great upgrade. Thanks RSC.

Glad to hear you're enjoying them and should have given you your 20RWHP back!

When I took my AM Vantage into the dealer for the annual service they really admired my RSC exhaust, thought it was super high quality and loved the sound over the stock unit.

Cool. Good to hear. I have one on order as well.

There are a couple of people in SoCal who are interested and may be buying the car. Don't worry though, we'll be getting another one pretty soon and we have some cool stuff in mind for this one. Watch this space...

Just installed the RSC exhaust.
Had the exhaust installed on Thursday. It sounds great. Not too loud. I think the biggest difference is the sound down low.
The shop that did the install could not believe it was a true bolt on. The had to do zero modifications to make it fit. One of the first for them, and they have been in business for over 30 years, and do many high end cars.
