Any recomendations for an exhaust replacement on the V6. I don't want a wizard as I'm not keen on the sound... Sorry I know lots do.
The centre section pipe from the cat had broken in half. So either i just replace that section or go for a complete cat back system.
Anyone used Cybox ?
Thanks Guys

I've seen and heard the systems from Alfaholics and I'm in the process of ordering one, just waiting for a reply from them. Have a look on their site at the exhausts and also read about how they developed them, including the reason why a Helmholtz resonator is incorporated. I've been in the back of a car fitted with an exhaust make by a competitor and the experience was painful as a result of the 'thrumming' sound, it didn't have a Helmholtz resonator!

If you are not sure what sound you want, can i suggest going to a specialist manufacturer/installer like Longlife?

I purchased a bespoke system from them 15 years ago and it is still wonderful. Best thing is that they will also tailor the sound to your liking, rather than an off the shelf option. Just an idea.

Thanks. I have Alfaholics twin down pipes , their centre section is £199+ vat. I might do that and get the last section when that goes. I've asked for quotes from Longlife and powerflex. I don't want a really loud or a drone noise on long journey's. She passed her MOT with flying coliurs except for the exhaust.

My back box was an advisory at the last MoT but I'm getting the middle box as well. All paid for today. I liken those loud exhausts to an attractive woman shouting, not attractive at all!

I would recommend Longlife exhausts. I have now had 2 156 V6s fitted with them and they are perfectly reasonable - they sound great without too much noise and dont cost the earth! That said, I still got a Raggazzon rear section for my Twin Spark Spider and I can't stop grinning.

Mine arrived today from Alfaholics, everything I expected. Extremely well packed. I'm hoping for some fine weather now so that I may fit them.

Yep, a Helmholtz is pretty vital to get a nice sounding exhaust on almost any N/A petrol. We can get serious volume from our catback systems without any boom or drone thanks to the resonator design. This is one thing you won't get at Powerflow or Longlife as they don't build resonators in house, they buy in pre-made packed silencers of varying sizes/shapes/diameters but they can't calculate Helmholtz chamber sizes the way a proper exhaust developer might. The chap who designed the GTV V6 Wizard cat-back system has built one-off systems / prototypes for Alfaholics before, although on Bertone GTVs not the 916.

On a standard GTV with all cats/manifolds present, our silenced cat-back system is actually reasonably quiet, but hardly anyone has one. Most people go for the full-fat noisy version, or if they go for the silenced cat-back its because they've decatted the car and its already loud. But I really enjoyed the silenced cat-back on my old GTV V6, and I have a silenced cat-back system on my 156 GTA too. For me, I prefer it to the unsilenced version.

Another nice exhaust worth considering for the GTV V6 is the Larini catback system, but these are 10 years out of production now, and only occasionally crop up second hand. If I can get hold of one of those I might be tempted to reverse engineer it, as it is a nice sound and very different to either the Wizard catback system or Alfaholics system..

I had a bespoke system fabricated onto the car while I waited by Fast Road Conversions Ltd. – Custom Exhaust Systems and Fabrication Kent in stainless steel cat back and one mid pipe (open (I think) silencer). I think you have been behind my V6 on one of the runs we did a few years ago in Kent/Sussex. It is loud everywhere but a good loud, I don't like the sound of the Wizard or other 'high pitched' exhausts mine is a deep sound;(I don't like quads or dual exits as they look a bit naff to me and not OE) and Fastroad fabricated the OE tail pipe back on for me. I am pleased with it over the last 6 years but too loud for everyday use but the car only does 1K a year, it was a good price too and the young chap who I watched fabricate and fit the exhaust was a proper perfectionist!
