Griff 500 NOISE options
Discussion
What are the options for exhausty noise on the 500??
I love the noise the car makes, however I have a sad addiction to overrun pops/bangs/burbles....
The bible states that some 'sports' exhausts or mods to the existing boxes can cause the noise to be too much for trackdays. I'm perfectly happy with the looks of the standard exhaust, and the performance - but a touch more rort would be nice without sounding like a SEAC wedge
Equally I don't want boominess on long motorway runs. It's a bit of a tricky tradeoff!! Anyone here had interesting things done to their exhaust??

Hello fella's.Friend of mine has a Griff 500 and has had his exhaust "modified" and his cat removed and it sounds fantastic.Ref insurance companies I don't think you need to inform them as you are only tweeking the db level and not increasing performance but come MOT time there may be a problem with emissions but I may be wrong

Mmmmm... I wouldn't be so sure. In my experience, an insurance company will do anything to wriggle out of paying out for a claim and not having any cats in your car, when it should, does constitute a modification.

A standard system can be borderline on noise at some tracks.
Mine is around the 97/98 db level & this is right on the limit for Goodwood for example.

Straight through pipes on silencer box + precats out...... (5.0 Griff)
Noticed more noise and a deeper burble. Car revs rise slighty quicker than before. My assumption here is slighty blocked or breaking precats.
No running issues. Would tell you the db at 4500rpm (trackday measure) but my meter isn't here yet

If you turn up at the Essex meeting sunday you can put your ear next to my 500!!!! sleaved box. sounds like a spifire on
I can second that, heard it on Tuesday, first of all from about 1/2 mile away!!! No good though if you like to listen to classical music such as Kylie and Jason whilst driving as you just won't hear it, if that's not convinced you to get it done...
