Arrow Larini Sport Cats for the Maserati Quattroporte

Larini has just completed development of the Sport Cats for the Maserati QP. Here are a few videos for those interested. It's always difficult to capture the true sound of any exhaust on camera but this seems to be fairly decent. In person it has a bit more bass but the video certainly does capture the real sound of the Ferrari V8 under the hood!

Enjoy!

Sounds awesome! It sounds even higher pitched than just with the Larini sports boxes in the rear. I don't remember what it looks like under my car, does this add HP? How does it sound in the cabin? I like the way my exhaust sounds it has the perfect rumble when driving, wonder if it makes sound even better, it probably does!

It's a bit higher pitched and a bit angrier than with the stock cats. You'll certainly hear the Ferrari DNA in this setup.

Although performance #'s haven't yet been released, conventional wisdom and comparison to past systems shows that the added flow should produce at least +10hp.

Also, a similar system for the Maserati GranTurismo will be available soon (High Performance Sport Cats)

The cabin noise is similar to before, the difference being that you hear a bit more of the higher frequencies and again it sounds completely unrestricted when the throttle is blipped as if the system has nothing holding it back.

How much do these run? and do they have to be welded in place?

I listened to this with some Ferrari techs and they were impressed. Sounds amazing. One asked if anything had been modified on the engine or drivetrain that would also be lending itself to that sound beyond just the sport cats and larini boxes. Jeff - do you know? I see its a UK car.

I believe all of the sound clips are with stock engines. Larini has the fantastic ability to really pull out the Ferrari sound from these engines.

Which clips are you referring to specifically?

Jeff - Am talking about the two links above in post #1. The thoughts were that the shifts were just too fast, the throttle response too fast and the sound too good for there not to have been other work done to the car. It really does sound great. Would be nice to know if that is just an out of the box Quattroporte with the sport cats and rear boxes and x-pipe or if there is more going on.

Great question, kramsay. I love all the larini videos, but the cars in them are always no joke sounding. That being said, I don't know how my QP with the larini sounds if somebody is recording since I never done that.

I do know when you're the driver, it sounds one way (smooth rumble)

As a back seat passenger, it sounds another way (you can feel the rumble on the seat)

And I know I've followed my wife driving the car and it sounds different as well (GREAT)

I know when my windows are open how it sounds, the rumble... and when I floor it the escalating sound, its intoxicating... Makes me feel like I'm operating a smooth machine, which I am... One of the smoothest on the road...

But this definitely sounds different than just with the mufflers, higher pitch, closer to an F1 sound... I likey!!

Default FD Upgrades Completed

Just completed the Larini X-Pipe and NEW Mufflers install along with all the other great stuff from FD and all I can say is WOW!
First the sound, the most mellow but thoaty idle (car sounds ready to launch just sitting there), unleash the beast and it sounds pretty much like the clip but just not quite as loud (didn't do the cats but thinkin about it already)
Did the 1.25" drop which really makes it look like a custom (ride is a little rougher than stock and I find myself paying more attention to the road condition and steering around stuff but I'm liking it also)
Best is the way it shifts and the performance increase, now it shifts like I had the gearshift and clutch (moves smartly off the line and changes gears effortlessly and I suspect with way less clutch wear) Performance, I can't give you the total report yet as it's raining here almost every day and I just breathe on the pedal and it breaks loose but me thinks its gonna scream.
Did the air filter and just for sh*ts n giggles put in the ferrari horns which will clear the road ahead when the headlight flicker fails.
Thanks again Jeff, you under promised and over provided.

Hi Guys,
I am the owner of the QP in the 2 video clips posted by Larini on YouTube and had the work done a couple of months ago. It has the Sports cats, x-pipe, link pipes and Sports rear boxes. The workmanship and quality is superb and the sound that this system makes is awesome!! I can also let you know that at the time the video was taken (26 September) it was completely stock...
Since then I have fitted Jeff's DBW enhancement module and am also extremely pleased with the results.
Regards,
Enzo.


Love your Life...

Default C.A.R.B. approved?

Was talking with a mechanic friend of mine about getting the Larini sport cats. The first question he asked me was were they C.A.R.B. (California Air Resources Board) or EPA approved. He then started explaining the fines for replacing, both to owner and mechanic, a functioning cat, increased pollution etc.

Any thoughts, insights, comments on this?

Is it worth getting the x-pipe and sport cats if theres already a tubi on the car?

QP_Sport, all aftermarket exhaust systems that we're discussing (Tubi, X-Ost, Larini, etc ) are not EPA or CARB approved. I believe that you're in Canada and are not governed by the EPA or CARB. I'm sorry as I do not know the regs up there.

The following emissions information is to the best of my knowledge:

CARB is for California only and basically you are not allowed to change any exhaust components (including mufflers) on street vehicles to something other than OEM.

My understanding of the EPA regs are that you're not supposed to replace any functioning emissions control device. There are provisions for replacing defective parts and of course your state may have other local regulations.

Keep in mind of course that dealers all over the country (including California) do replace mufflers often with aftermarkets, which is technically illegal. They may have you sign something stating that its use is for off-road use only.

From what I've seen on the Gas Analyzer the Larini products clean the exhaust better than the factory parts as they are a higher cost, better engineered part. However that may not mean that it's legal in your area simply because it passes the emissions "sniffer" test.

MYBigMac, adding the X-Pipe or Cats will have the same benefit with or without the Tubi mufflers. Basically, with the X-Pipe you'll get more flow, volume and more of the Ferrari Tone. Adding the Sport Cats will provide you again with improved flow and a bit more of the "race" sound.

Best Regards,
-- Jeff

Thanks as always for the straightforward explanation. And if worse comes to worst, it doesn't sound like it is too difficult to just swap back to OEM! I am keen to install them but it depends on whether Santa (i.e. Wife!) thinks I have been naughty or nice. (Naughty with her OK, naughty a la Tiger, bad!)
