time for a change......

but I'm just looking to change the pairs of exhaust boxes in the search for more sound and maybe a bit more performance or at least not losing any, but to ensure I can make the odd track days that means Gert's RSR's are out for that reason...

so what are my options...... Cargraphic ? Techart ? ??
 
In terms of sound I prefer the fabspeed maxflo, they are better value than either cargraphic or techart...both of which are quality items.

In terms of noise they are getting so strict at trackdays, that I am happy to run a standard set up, safe in the knowledge that there is not a toss of a coin scenario whether they are quiet enough as there can be with some after market exhausts.
 
In all the stuff I have read, there has been no mention of the RSRs being too noisy for trackdays - just a different noise. Have I got this wrong and, if so, I need to know now I think, before its too late.

RSR's too noisy for tracks!?sh*t I'm getting some fitted today.. didn't know about that - anyone here have them and regularly track?
 
My 993 with RSRs was fine at Donnington on a quiet day. I'm not sure who started the rumour that they were too noisy for track days. They definitely are the best VFM exhaust box you can get. I'm in the West Midlands let me know if you want a listen.

I returned my RSR to Gert, they sounded great but on a standard 993RS they were slightly north of 105db on the static test....which was not worth the risk for trackdays as far as Iwas concerned.
 
Were you statically tested at Donnington or was it only drive by? My E makes 104db static but still has no problem drive by a Donnington.

If you're interested I have a pair of Fabspeed Supercup boxes for sale (see http://www.fabspeed.com/993.html). They're in very good condition, although I'm afraid I don't have the turn downs. You may be able to source them direct from Fabspeed, but to be honest I'm not sure how much use you'd get out of them...

They were £595 new - any reasonable offers considered!

At Castle Combe and Goodwood you'd be spending the track session eating your sandwiches in the car park.

It's not the problem of the circuits and the noise police, it's caused by people with one brain cell buying a house in the vicinity of a race track that has been established for over 50 years and then bleating to the council. Castle Combe which is probably the best run and best club circuit in the country lost the F3 and British GT meeting this year due to the above. Goodwood have the same problem and if you talk to circuit organisers it seems the rot is spreading.

Seems that anything related to the use of fossil fuels gets kicked in the nuts. You may be able to get past the noise levels if you stated to the council you were seeking assylum, showed terrorist tendancies or were of a sexual deviant nature and relied on state benefit, instead of a law abiding tax paying member of the community who for pleasure maintained and kept pristine a car you worked hard to buy with your tax paid money.

Can you be specific abou the static test? What rpm and at what distance? Also, what did you record with the standard exhaust?

I have a full cargraphic system on my 993 c2, that is extractor manifolds, 100 cell cats and tips it made 105db @ 4000rpm at both Castle Combe and Goodwood this month (CC noisy day) and was fine all day long no matter how hard I pushed it (and it was hard).

I have a couple of the exhaust bombs you can buy at merlin motorsport at the combe circuit, and I had my local blacksmith fab up some pipes plus flanges and I replace my tips with the extra silencers on quiet days and the noise reading drops to 98db :)

I used to have RSR's on my otherwise std engine (before it was modded) and it made between 99db and 102db @ 4000 rpm and FAILED at CC on a quiet day, was OK at everyother circuit, Goodwood, Bedford, Donnington, Brands I visited. When it failed I had to go home and get another car as i was not allowed on one time :-(

Interestingly they allowed me to try a few more times and the hotter the car got the lower the noise but i couldn't get it to 100db or lower.

I still have the RSR boxes in the back of my garage if anyone wanted to swap back to original as I don't need them with the cargraphic system.

Ideally i would like also to swap the Bischof manifolds i have for Gillet, I have the full system, manifolds, cat, RSR boxes, chrome tips.

Fabspeed looks interesting. . .

what's the difference between their Maxflo exhaust and their Supercup system ?? no seeing it!
 
Oliver,

I may well have mail - but I don't know how to get it! The InBox feature for my account is disabled - something to do with privileges, apparently. That underprivileged childhood returning to haunt me, no doubt.

Try johnboult@hotmail.com if you need to get hold of me.

Cheers/John

have a look on here, www.fabspeed.com maxflo are like a regular sports muffler / back box....the super cups are not so much silencers, more like trumpets from the cat back that sound like you have unleashed the wrath of Hades...probably fun for an hour or two..but don't ever think about doing a trackday again!
 
Oliver, I too cannot access emails, no permissions, usual story. please email me at jspear@jmspear.demon.co.uk.

BTW, didn't notice the WWII Mustang failing a noise test when it took off at Goodwood @ Lunchtime this Tuesday, yet the 996 GT3 RS with the trick exhaust did - and off he went to eat sandwiches all day, and it was a LOT quieter than the Mustang :-(

Seems if you burn unleaded you are bad, Avgas good !!!

Hi Sundeep

Pretty sure I have seen Fabspeed offered by Essential Styling in their 993 section. It includes a comment stating about liklihood of resonance inside the car.
