Larini, Quicksilver or other on a NP Vanq?

[ARAF]

I need a new rear box on my Vanquish S. I'm not looking for anything noisier than the standard system and so am therefore leaning towards the Quicksilver as it has a bigger silencer.

Has anyone compared both?

Is there any other system I should be looking at? Do Bamford Rose make one and how much are they?

Answers on a postcard.

There are a number of different quicksilver backboxes, from loud to my-ears-are-bleeding-make-it-stop-please. Listen to a few and see what you think...

Thanks.

I think I'll fire off an e-mail, to see if theirs can be repacked, if I've chosen wrong.

Most aftermarket exhausts will be louder so is it a different tone you're after or simply a replacement backbox of some description because yours has rusted through or otherwise sustained damage?

I have a Larini box on my v12v. It's make you jump on start up bit settles as the car warms up and the revs go down at idle. It has no valve's so will always be louder than the std box below 4k revs.

Both inlet pipes to the rear box have broken so exhaust gasses (and noise) can escape before entering the silencer. Speaking with the guy working on the car, we're going with the Quicksilver as they have one on the shelf. Better than the cost of a standard silencer.

Nice, is that the GTE or ST silencer?

Also, Did you fit a decat or sports cat?

[Buzz Killington]

Honestly don't know, only recently bought the car and found the Larini box after sale whilst wondering why the exhaust valve remote kit I bought wasn't working. Need to borrow a ramp so I can get underneath and do some look see. No decat though, as I still have functioning ears.

Amusing party trick though in that it sets of car alarms of cars parked to close when she fire up.

Thanks for that - I think I’ll start with fuse 15/22, and maybe then freer flowing secondary cats.

I met with Josh at JH Pearce Chobam yesterday, he was of the opinion Larini was of better quality, but QS is what they use on the competition variants.

Yes the guy that fit my quicksilver was not impressed with the quality at all he said it was shocking

Cheaper than an AM back box.

Hopefully it was an off-day as it has been ordered.

Thanks to all who have replied. I will report back with what I (and the garage fitting it) think of it to maybe help others.

Quicksilver fitted. Pops and crackles going up or down the gearbox. Lovely sound.

I had the CCCharger keyfob fitted by the man himself as he is very close to the storage place I use.

Works well for me, and as someone who is not seeking performance improvements, may stick with this solution.

Primary decat is obviously risk mitigation as well as sound and bhp improvement, so not ruled out completely.

Get it welded, keep it original.

It'll break again. The valves are jammed as well so the back box is at the end of its life.

My '05 Vanquish came to me with a Quicksilver (and the original system on a pallet). I doubt I'd have chosen to change the original, but the sound with the Quicksilver is absolutely epic -- and I haven't put the original box back on the car...
