Griffith exhaust mods

[JKY]

Much to my surprise, I now find that my Griffith 500 exhaust has been modified by a previous owner! Silencer has been peeled open and entire innards have been crudely removed then welded closed again. I re-opened it to find this and now have a dilemma as to what to do next. It is currently an empty box with just the short stubs from the old pipes remaining either side. Understandably it resonated badly!!.
Do I -
A) weld in straight pipes, pack with wadding and weld shut - most of you will recommend this I guess, but in reality is it TOO loud !!! BTW, precats are still in place and will remain so.
B) weld original type baffle pipes in
C) Drill some holes in straight pipes to allow a bit of silencing, but how much / many??

Any opinions / other suggestions appreciated.

If it didn't have any wadding in it would sound tinny apparently. Mine's had the mod with the wadding put back and it's just about right

Quinny, I would seriously have considered that but Shropshire to Berkshire is a long treck and guess a courier will be VERY expensive.

but that could be so expensive Quinny!!

[JKY]

Having opened the existing one up the car is now undriveable and maybe I should be taking the oportunity to make it a decent sport system. Why did you take your system off at 11K? Too quiet? What do you have on it now?
I will wait to see what the general consensus is however I will not totally rule out buying yours if that becomes my best option.

Is that the one ACT sell?

I think so, but I got mine direct from JP as they ain't that far away, so I collected it and got a good deal

Do you know if it's louder than the straight through mod?

I want something a little louder than that (not full decat loud) but with a deeper burble.

No, if I had wanted a pre-production Griff I'd have said that

cheeky sod!

Cheers Quinny, although thinking about it, any form of silencer is going to be quieter than my straight through

This is what my 'empty' silencer looks like currently!!!

How about 30mins from M4 J17...My old zorst is lying around gathering dust.
Its done mileage but is sound, just needs a damn good clean up. email me if you're interested.

[JKY]

Thanks bluebottle, I will consider this as an option however I really would like consider having a go at rebuilding my current one into some kind of sport system first.
What did you put on yours as a replacement?

[clive f]

if you want a sports style system just weld in 2 pieces of 2" tube to the ends of the pipes inside your silencer, but still pack out with some wadding to cut out any tinny sounds that the silencer may make.

[JKY]

This is the really loud approach though!. It is in a consideration however. Anyone have any results with part perforated tube / part straight?
Also I hear good reports on the option of welding in a pair if cherry bomb silencers inside the box??

[HRG]

It's not "that" loud if you've still got the cats in IMO.

why bother if you don`t want it louder then, if you really want it that quiet, then your only option is to return the silencer to its standard form.
sports exhaust are labelled "sports" as they are designed to increase performance, and in doing so are not as restrictive as the standard system, the drawback, if you call it one, is a louder system.
some like them, some don`t.
