Larini's fitted today

[mjheathcote]

Blimey, what a difference.
They are quite loud <3,000 rpm, loud as in very deep, >3,000 rpm they tone down quite a lot, can see no problem on the open road/motorway.
They are unvalved rear boxes, rest of the system is stock.
Those with valved rear boxes, where is the difference? ...I assume not as deep <3,000 rpm?
Currently no sneeking home late at night!
Cheers

Make a difference don't they Mike. They get better with time as well. Give at a couple or three months and they'll bed in nicely.

 

[Mr.Cambio]

Wake them up!!!!

Congrats Mike!

 

[mjheathcote]

They are really deep sounding at low revs, is that normal?
Just cant imagine having replacement pipes with no rear box at all!

Combien Mike ?

Combien Mike ?

I bought them secondhand for £700, fitting came to £185 at my local indie, lots of seized fasteners apparently, should have been more but they are trying to win my custom!

This very deep drone less than 3000 rpm, I've done a bit of digging, appears common with the Larini rear boxes.
An old post suggested that the larini link pipes solves the problem, and one member confirms this.
From the larini web site:

"does not vibrate or drone"

Don't know how much these pipes are, but worth investigating...

Would love to replace my backboxes with full system.....

On the next one.....backboxes are excellent though

Cheers Mike, good to know.

They sound glorious and a few strangers have told me as much in passing - a bit of pootling around town is required to avoid upsetting the locals but on the open road..........

I love them but she who shall be obeyed wants something a bit less banshee (she keeps reminding me that I'm knocking on the door of 50 so need to start taking it easy!) - they're being replaced today by a pair of Roberts Aerospace boxes.


Straight through pipes will be on ebay tonight for the harder core owners.

Spoke to Larini this morning, and they recommended fitting the H pipe to reduce the tone at low rpm.
Can't see this making a difference to be honest, if anything, making it louder! The original centre centre section is silenced, the H pipe is not?
They did say replacing the link pipes would make no difference.
They where quick for me to speak to Performance Italia though, as their Maserati distributor.
Anyone fitted the H pipe with any comments to the tone (drone?) at low rpm?
Cheers

This is very interesting. I had the Larini's taken off mine because of that drone - the noise when sitting idle in traffic (which I do a lot, living in London) was too much for me - much as I loved the noise when hooning. I went for a custom system which is great - lots more noise than stock, but not too much noise, and certainly no drone, when idling. However I do sometimes wish for a little more drama when I'm having fun with it. The only cars I've spent much time with that had Larinis on only had the backboxes - so very interested if some other part could solve that drone issue.

 

[Parisien]

Drone on my straight throughs at 2500 revs......learned to live with it...nice racket when presed though........also have a larini H pipe not sure it makes much difference apart from being 1/2 the weight of the centre section

I have larini backbox ony and would not want it any louder- especially when starting in the garage

 

[stradaman]

Droning, could be a fitment fault. It maybe picking up noise from somewhere. Floor? Bumper area?

[mchristyuk]

Have straight throughs on mine too.. not obtrusive in the cabin (even quiet on the motorway!) but sounds awesome at idle and the red line

Did exactly the same with my old 4200. Larini Back boxes first then H. H made no major difference to sound - if anything it was louder.

2.5-3k revs drone too much for me so sold both. Fine on the road but too much day to day in traffic.
