I installed a Quicksilver exhaust system over the holiday weekend. I replaced the stock muffler with the crossover tubes, and the secondary cats with silencers. See photos.

After researching exhaust systems for a few weeks, I decided on a Larini system.
When I called the USA distributor, I was told they do not rep the manufacturer anymore because of quality issues.
I also researched the Kreissieg, Capristo, and Tubi systems, but could not get consistent information and opinions. And besides, aside from the Tubi, they all look so complex. I find it hard to believe that when it comes to exhausting an engine, more is better.

Anyway, it sounds great, and it's not too loud. And it's so much lighter then the stock setup. It looks real good also. Too bad you can't see it with the heat shield on. I also noticed that there seems to be less reverberation from inside the car. It may have something to do with me even-ing up the clearance on the primary cats. They really jam them in there. In fact, I don't think the engine can move on the mounts freely enough without pressing on the cats and heatshield against the frame.

As for the quality... it was crappy. Good thing I own a fabrication shop!
I had to pull a dent from one of the silencers. I also had to cut and reweld the flairs that connect on the engine side. While I had it in the fixture I made from the stock system, I also added a set of supports to utilize the rear muffler shock mounts. I was afraid the tail pipes would wobble without support from these.

We are kicking the idea around at our shop of building a titanium version of this system. I would like to remove the primary cats and put them in the extra space the stock system took up. We can replace them aftermarket ones or try to make titanium cased ones.

What kind of shop is it? What kind of work do you guys do there?

Very Cool. The first thing I did with my 5.7 is install Tubi myself also. I have the quicksilver silencer, but on my car sounded too quiet and hollowed out the stock cats to get a nice deep sound. I think the build quality from all the aftermarket companies is not that good, considering the price we pay. Even the tubi had minor alignment issues that I had to tweek.

I like the idea of the bracket to keep the tips from "shaking". I noticed my tips will vibrate slightly at idle... some say it makes it look meaner.. I don't know. Think I'll also try a bracket.

Re: primary cat - my car is OBD 1 so no problems, but you are aware that on your OBD2 if you pull the primary, you'll set off a check engine lights.

I would just move the primary cats with the sensors to a new location. This way I wouldn't get the chk engine lights. I also feel there should be a short length of flexable tube from the engine headers to the cat, silencer and tail pipe connection. I would put this flex tube where the primary cats are now.
I think the engine has more ability to move freely then the exhaust. This may cause some of the reverb we here through the stiff structure of these cars when we accelerate hard.

Just put the Larini exhaust on my 97 roadster. The sound is simply amazing- I'm very glad I did it.

Keep an eye on the welds.

Hey, guys I guess you forget that I am THE Larini Dealer.
I also deal in Lambo parts, and have been doing so for over 25 years.

Hey Chad, have you ever taken a fuel tank out oif a Countach ?

Sorry Chad

I wouldn't have known. I just started here.
When I would search Larini only one or two US distributors would show up.
Anyway, once I decided, I overnighted it and had it the next morning.

Keep an eye on the welds....Or your tail pipe position
