Does that extra inch really make such a big difference...?
Discussion
Afternoon all.
I've nearly saved up enough pocket money from my paper round to buy myself a new musical instrument and was wondering if I could pick the brains of any 2bular exhaust fans. I've poured over the 2bular website and can't decide whether to go for the 6" or 7" stage 2 type. I've read Janitors excellent fitting guide, and watched his 'before and after' video clip for the 7" exhaust, but try as I might, I can't find any video of the 6" example. What I am trying to gauge is how much louder it is. Track db limits aren't really an issue as I plan to refit the original pipe for the couple of days I do per year. So that's the question I need to ask. Does anyone here have experience of 6" over 7, and how do they stack up against each other...?
TIA for any comments, Chris.

Sorry Chris, no first hand experience here of the 6" version to offer either!
Best bet I reckon is to call Jim himself and have a word. I'm guessing that the 6" will have a little less wadding in it so be a touch noisier than the 7" - not necessarily a bad thing, but the 18" x 7" one that I have suits me perfectly in that it is as sedate or as raucous as I want it to be
Mmm.... 2Bular...

For those that are interested I took the plunge this afternoon and ordered one of Mr Valentine s systems. I plumped for the 6" x 16" twin tailpipe design. Jim says it's an absolute riot when on second cam (106 - 107 db...
) but nicely throaty and meanacing on a gentle cruise. Can't wait for delivery, and probably won't be able to fit it for a while as I've got a road trip up to the Highlands of Scotland planned early July, but check back here soon for details of how it sounds...

Have a chat to Jim, he will ask you what you want from the 'zorst and how you intend to drive it (track days etc). Dont get fooled into the max muppet state of mind that noisier is better. I have the quietest zorst that jim makes and it is someware between a lotus stage 1 and a stage 2 only far better sounding - it is more "melodic". It is able to get on most tracks (thruxton may be a problem).
Joe has about the loudest and you can tell from about a mile away what he is doing. There is a fezza 430 with a "sports zorst" in town and Joes 2bular sounds better!
The build quality is superb and they are very LIGHT! Jim will allow you to specify the tips you like. Mine are descrete like a stage 2, SimonK's stick out all the way to the numberplate - like a couple or rocket launchers!

As Gooby says the best thing to do is explain to Jim what you want from the exhaust and how you will be using the car. I have a 4.75" dia Ultra with twin 3" slash cut tips through the diffuser, which sounds absolutely fantastic. Yes it is loud but not loud for loud sake, it has real character to it. It starts with a deep bass rasp at low rev's then turns into a very hard superbike\F1 style scream as the rev's rise towards the limiter + Lots of pops and bangs when you ease off along the way. (Every time I come across a bridge\flyover or better still a long tunnel I am left grinning like an idiot) + From a performance perspective the Ultra works really well with the supercharger as it is so freeflowing.
However I accept that this exhaust is way way too loud for any trackdays - This is why I have kept the standard exhaust and have got my self competent at changing it over easily for when I finally get around to doing some trackdays.
The other advantage is that I live 10 mins walk from work so only use the Exige when I am in the mood for a blast. If I had to use mine everyday or did regular long motorway journeys or trackdays I would not have gone for an Ultra.
In summary it all depends on how you intend to use the car and whether or not you mind changing the exhaust over for trackdays.
Enjoy!

Couldn't agree more with Gooby about falling into Kevin the chav teenager Max Power mindset ! If I'd wanted that image, I'd have bought an old Corsa and stuck an industrial drainpipe on the back of it - tw@ts. Jim assured me that the 6" doesn't sound at all chavvy and in fact it was his favourite system for the 111R. I'm also in the same position as Joe, in so much that I don't need to use the car for work and can keep it as a toy for sunny days. (remember them?) It'll be changed over for trackdays so db limits not an issue. Cant wait !

Just thought I'd put a full stop under this long-running thread.
Finally got around to fitting Mr Valentines creation the other day, so I thought I'd post up some piccys for you enjoyment. Jim reckons it comes in at around 105db when the second cam really makes it sing, although it's reasonably civilised at other times (barring the odd pop and bang). I reckon it weighs only about 40% of the original unit.
In short, it's everything I thought it would be, and at anything over 6k rpm, it gives the Elise the racing car sound that matches its looks perfectly. As others on this forum have said - 2bular...
