Vortex Exhaust.
Discussion
Has anyone tried one of these on a Cerbera.
I currently have the ACT large bore sports pipes feeding into their quiet back box. I find the current system rather frigile and have it welded regularly so as the back box is now fubar I would look around and see what is out there.
I like the idea of a back pressure free solution but thought I would ask what others have done and what their experiences are around this topic I know there has been some debate around linking the exhausts near the front and other design options.
Joolz, please feel free to add your expertise.

Worth a google but there was a long debate on linked pipes just after I got mine so 2006-2008 sort of timescal" I cantt remember if it was decided it made a difference or not.
I had real issues with the original design of sports back box. Wasn't as quiet as claimed, wasn't well made or fitted, damaged my car.
In replacing it without a ACT 'sports' style system, i found I had a lighter system, more roadclearance and it's been on now for ten years

I have an ACT rear box, and linked decat pipes. I replace them with cats each year for the MOT but the different on easy revving when I take them back off is really huge. The linked pipes do seem to help as before I had single non linked decat pipes
They also help with positioning of the tail pipes. I hate seeing Cerbs with the tailpipes out of position or off centre. BEcause the linked decats allow you to vary the distance in between, and the length of each independently they do a grand job of manipulating the tails pipes into position. I have done this so many times for MOTs that now all I do is loosen the decat lengths and crosspipe. Move the tail pipes into position then do everything up and presto. I threw away the bracket I used to use for all of this.
The ACT rear box was important to me as the car is used occasional for work and I wanted free flowing but easy on the ears. It has the benefit of even with the decat linked pipes and rear box being track noise friendly.
Don't know anything about a vortex exhaust but I'm pretty happy with current setup.

What's the noise levels with your exhaust? with the SP box you needed the cats in to meet their claimed noise levels to be trackday friendly. Cats lower the noise by 8-10db
I run at 106db without cats, so easily drop to today's track day limits with track day cans added to the tailpipes.

Current system is all ACT, balanced headers feeding into the large bore silenced decat pipes and a quiet back box.
Noise is not the problem I usually get measure at about 96Db at track days but the system is made of chocolate.
I have a constant chuffing from where the OS manifold meets the down pipes as the mating surfaces are not flat enough, I have had down pipes shear in half on track days and had to get them welded up at Spa, guys that fixed it had to weld a bit of extra pipe in as the originals were not long enough so were under constant stress that when you add the heat stress of a Spa trackday caused the failure. I am on the second back box due to the internal welds breaking and the baffles coming loose.
I just want an exhaust that fits, sounds epic and does not keep failing so I thought about biting the bullet and considerable cost and going to Vortex to get them to make me one from scratch using some of their interesting sounding zero back pressure units but before I went down this route I was wondering if anyone else has tried them and if they actually do what is claimed.

Oh yes the guys who did the welding are great blokes next to the Hotel De La Source http://llm-mecasport.be/en/ if you ever need something fixing. They opened up for me as it was a Sunday morning and had it sorted by lunch time they really know there stuff.

The raceflo exhast says at least 10percent more power. That would put a 400hp cerb to 440hp .. hold them to that claim if you get it done. Ill test your car before and after for free to find out lmao.
When you speak to them they do say the raceflow needs a remap after fitting so I may well take you up on that offer;-)The 10% will mostly come from optimising the map and nowt tip do with the exhaust.
