I needed ( possibly wanted rather than needed) a new exhaust for my van. I realised that the off the shelf exhausts were poor quality and as my van is a motorhome the standard ones did not fit. The brackets were in the wrong places etc. I have had a number of custom stainless steel systems on cars but all they seemed to do was sound good, they didnt improve performance or MPG. I heared about a company called Vortex in Grays Essex and noticed that they had been in business a long time and offered a patented vortex system which promised to improve power and MPG. As a sceptical northerner I thought extra power and MPG were myth, we have all seen the so called magical MPG improvers sold on Ebay and at shows and snake oil comes to mind. The vortex company have a great website and supply systems for bikes, cars, busses, taxis, trucks and ships. I couldn't find any bad feedback on the web and after loads of research and putting it off I booked my van in and had the system fitted yesterday.
I thought I would let you know all the differences I noticed while driving home.
The system they fitted was designed to be very quiet has 1 vortex and 3 straight through silencers. They know exactly how many and what size silencers to fit to give you the sound level that you require. I wanted mine very quiet. They don't hang low down like the original one so wont hit bumps in the road like my old one did
My van is a 2.8jtd pulling 4.5 tons on a TAG axle luton motorhome body (brick on wheels).
On pulling away my van was quieter, smoother and had more throttle response. Right through the gears and rev range it was smoother and quieter, I could hear a slight extra rumble when under harder acceleration where before this would have been a louder courser roar that would drown out my radio and make talking on my Bluetooth hands free impossible. I can now use my phone on hand free at all speeds, this was not possible before. I used to have to louder and lower my radio on the motorway with speed which I now don’t need to do. On hills I have noticed a great improvement and once past the war zone of the M25 I put the van in 5th gear and it stayed there for around 200miles until I left the motorway near Leeds, this was not possible before. Overtaking slower trucks on hills used to be a gamble as sometimes they had more power than me and speeded up causing me to have to pull in behind them. On my trip home this did not happen and bearing in mind I never left 5th gear this is even more surprising.
My van feels like a newer vehicle, quieter smoother and less stressful to drive. It’s possibly safer to drive as I don’t have to keep messing with my radio or changing gears.
On my trip out I used 58.37ltrs of diesel and the trip was clear roads with very little wind. On my return trip I used 51.63litres but the trip was 2 miles longer and the weather was windy pretty much all the way, I also got stuck for a bit in traffic and the van was filled before they did the emissions test so some fuel will have been used for the tests and during the exhaust fitting.
No negatives at all a great system and great people to deal with. Both knowledgeable and friendly.
