Exhaust wadding removal

[roysum]

Has anyone..... had just the wadding removed from their silencer, as opposed to the full sleeve job ?
If so, I would be interested to know if they are pleased with the result.

Thanks, Roy.

Wouldn't that sound really tinny?

Imagine wacking a stick around in an empty dustbin.

get yout money out and get your self a sports exhaust fron a.c.t.sounds very nice, raspy but nice when cruising and allso has the correct back pressure.its the type of thing i would go for when ive sorted the mechanics out.

Ok chaps, this is the position...........

Put it in this week to Neil Garner for a full sleeve job. He reckons it will be too loud. So suggested I try it with just the wadding removed, in his opinion it sounds better. If I'm not happy I can take it back for sleeving. So roll on Saturday ! I'll let you know.

Cheers for your opinions. Would still like to hear from someone who has just had the wadding removed !

I thought you would probably have twin 50mm copper all the way from the y piece, maybe the od yorkshire or end-feed fitting here and there !

Wazzal had some of the wadding removed (but not all). IIRC he was showing about 117db against my fully sleeved 121db. Cant comment on the quality of the sound, he was behind me for the whole hoon......

I thought that plumbers do every thing in Polypipe now i know it will stand hot water temps not sure about hot exhaust gases though

Roy, I had it done on a Chim 500 I previousely owned.

The noise improvement was noticable; sounded good.

The trouble came with the amount of damage the increased noise / vibration caused to the box the wadding had been removed from. There was so much vibration, it actually damaged the the exhaust and I had to replace the complete exhaust system with a Sports Exhuast (with Cherry Bombs) from Tim at ACT Performance.

If your going to remove the wadding, then in my opinion you need to cut out the perforated pipes also, and sleeve / replace them with ss pipe. This will give you more noise, but no increased noise vibration (if that makes sense?)

For what its worth, with the benefit of hind site, I would not do it, as you may well end up having to fork out for a brand new full exhaust.

When mine was sleeved I had the wadding put back in - this cuts down vibration and resonance

Roysum,
You were asking about what had been done to my exhaust a while back - blue Griff through Hermitage!.
My system is totally standard, including cats however it does sound louder and it rings a bit at certain revs - I suspect that my wadding has partially disintegrated. Sounds great but the ringing can be a slight annoyance.

Mine sounded awful - produced a turbo like whistle at anything over 3000 revs and no pops and bangs

Too loud?, no such thing

[Slikk]

Mine has no wadding or pipes in the box at all. Or pre-cats. Low revs it has the "Two Fat Blokes Wrestling At The Bottom Of a Muddy Well" sound, higher up the rev range it snarls. Pops and bangs aplenty.

[nawarne]

Both myself and TVRLee have had about 50% of the wadding removed from the standard box.

The sound is OK, I would not describe it as 'tinny'.

I did mine to improve a db reading of 92.1 to something a tad more befitting of a TVR.

Got it back, sounds awesome. Yes there is a high pitch scream when pushing it which I quite like. Time will tell ! Doesn't seem to be any noticeable vibration, which did concerned me.

Can recommend Neil Garner, nice guy and staff, nice set up. He has also fitted a Tim Lane roll bar for me.

Thanks everyone for your help / advise !
