The legendary Harry Flashman seems to have found an independent worth a look and has detailed his experiences here - http://www.pistonheads.com/gassing/topic.asp?h=0&a...

Just in case you fancied avoiding the usual suspects.

Yes Paul , I am concerned about the long runs and how tiring it might become , read somewhere that the Capristo's can be programmed with different sound levels in case it gets a bit nausiating .

Thank you for your enquiry.
We recommend the Seca exhaust for your Lamborghini Diablo – the Capristo is a little on the expensive side, and although it is the best exhaust, the Seca produces a sound almost as good for much less money. If it the Capristo you want though, do let me know and I can price you on that. I’ve put together some info on the Seca below:

Technical Information and Guidance

Although there are various models of the Seca Exhaust for the Lamborghini Diablo - we have chosen not to supply the quieter variations of the system and now only really recommend to the Level 2 system

So here are the options available for the car:



1. Normal version – Level 1

2. Loud version - Level 2

3. Extra loud version – level 3



We have chosen not to supply the normal version of the system at all. This system gives a sound which is far too close to the standard exhaust and is for customers looking for a only a little bit more sound than the stock unit - it can therefore be a bit disappointing for a customer looking for something substantially different! On the other hand, the loudest model is typically specified by customers looking for the most extreme sound possible.



One of the key things to remember with the Seca exhaust for this car is that it is NOT a simple straight pipe, or a crossover - all three systems are proper mufflers. They all manage to hone the exhaust note instead of just delivering maximum volume with no tonal quality. Both the latter two options give the Diablo a roaring scream - not just a flat bassy sound - it's got a richer, fuller and more "expensive" sound than any straight pipe configuration.



In addition, what makes the exhaust system unique is that it can be specified to include special chrome polished end tips (in different variation) which eliminate something called the ENCS (Lamborghini's Exhaust Noise Control System) - these are the sound control valves which are located on the original end tips. Getting rid of them with the Seca means that you ALWAYS get a great sound from the car - when it first starts, on small throttle openings, and through the gears, with popping and cracking and flames on the overrun. In addition, the tips look great too and fill out the back end of the car without looking overly aftermarket making the stock tips look just that little bit weedy.



Both the latter two systems weigh perhaps 1/3 of the weight of the original system, letting the owner drop weight from an important position (i.e from behind the rear wheels!) and massively reduce backpressure. A main dealer who dyno-ed the car said the full system with end tips gave an early Diablo 20 bhp which is a very large power increase for a bolt in cat-back exhaust product on a normally aspirated car!

Seca Competizione



It is worth making a note of who and what Seca Competizione are. Located in Italy, and born of experience gained in Formula One and long years of motorsport exhaust fabrication, Seca sports exhausts systems are focussed on delivering the ultimate sound for each performance car whilst maintaining originality and practically. Each system is lovingly hand made in grade 304 stainless steel to give an impeccable finish and outstanding durability. Seca Competizione themselves have a long background in the most extreme applications of exhaust fabrication primarily in Motorsport, including the FIA GT Champship, Formula One, ALMS, and the World Rally Championship. Their emphasis on delivering a quality exhaust sound without downside and it is what distinguishes Seca from other exhaust manufacturers in the market place today with some of world’s finest products available.

I hope this helps. Please do let me know if you have any other questions and I will be more than willing to help.


INTERESTING EMAIL I RECIEVED FROM CAPRISTO WEBSITE . PRICES APPEAR OK TOO !!.

The exhaust on my 99' SV idles at around 126dB and for about 30 mins on a run it's tolerable, beyond that I have to wear earplugs. A friend in an F430 can't hear his car above mine :-) in terms of MOT, find a sympathetic garage, my local doesn't even bother with the emissions test as long as he can take photo's of the car :-)

My db meter says so.

Fair point on the weight saving.I had straight through pipes done and lost the cats.Now they weighed loads! Coupled with the standard muffler being removed,must have saved a fair bit of lard.

Thanks for that Fyfe , will check them out when back in Blighty

I would love to be proven wrong but my guess is either your meter was found in the bottom of a Corn Flakes packet or you have the mic of the meter stuck in the exhaust !

It's a quality meter but perhaps I am holding it a bit close ;-) I'll try to do a video later today with it at various distances etc.

Given we're talking about measuring the noise from a Car and not something attached to the HLC, I calibrate it by drinking a can of Wife Beater as fast as I can and then burping into the dB meter.
