grumpy the 7th Posted March 24, 2020 Share Posted March 24, 2020 Hi, my silencer exhaust is ready for another fix or replacement (legacy of a kid standing on the exhaust to look in the car a few years back) the short inlet pipe cracked on the weld where it's joined to the front of the can, this has been rewelded 3 times now. After a period of time the front of the can seems to tear away from the new weld so it looks like the front of the can is suffering from metal fatigue. I was wondering about either a new CC exhaust or a raceco one.Does anybody know how hot the raceco body gets after a good blat. (the standard CC silencer has a heat guard and SWMBO only has little legs so I don't want her burning herself.Thanks Link to comment Share on other sites More sharing options...

7 wonders of the world Posted March 24, 2020 Share Posted March 24, 2020 Since there made not a million miles from you I would pop along and see what can be done in exchange for a few beer tokens....The weld quality on newer cans has deteriorated since I had my Raceco, the end caps are spun and so are pretty thin hence this aids lightweight of the system.Are you mounts fully supporting the system or do you have baggy bobbins..?

grumpy the 7th Posted March 24, 2020 Author Share Posted March 24, 2020 Johnatan, hi. Just the one bobbin at the back of the silencer.& wonders, Hi, No! no saggy bobbins, renew them every couple of years and carry one in the boot.I just think the front of the silencer metal is sha££ed out after a long squark. Could be due to being welded too many times? Link to comment Share on other sites More sharing options...
Titanium7 Posted March 24, 2020 Share Posted March 24, 2020 On my 3rd Raceco exhaust (3 different cars) and have never been burnt by the actual can, the headers and tail pipe are a different matter! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 24, 2020 Member Share Posted March 24, 2020 Is there a reason for not having a front bracket? I don't know which exhausts need them and which don't.But I do know how to find the front one through the skin!Jonathan Link to comment Share on other sites More sharing options...
grumpy the 7th Posted March 24, 2020 Author Share Posted March 24, 2020 Don't think the front one is ever used is it? I've not seen any (or many) with this used. Link to comment Share on other sites More sharing options...
Nigel Fox Posted March 24, 2020 Share Posted March 24, 2020 If you get it repaired have some gussets welded between the inlet pipe and the end cap. Link to comment Share on other sites More sharing options...
grumpy the 7th Posted March 24, 2020 Author Share Posted March 24, 2020 Nigel, Is that what Claire Rayner advises for her gussets?? and I thought it was Red Bull that gave you wings Link to comment Share on other sites More sharing options...
StevehS3 Posted March 25, 2020 Share Posted March 25, 2020 Hi Grumpy, if it is a standard K series exhaust they come for sale quite often (and quite cheap as they often don't sell) when folks upgrade to Powerspeed etc. Link to comment Share on other sites More sharing options...
SM25T Posted March 25, 2020 Share Posted March 25, 2020 My original CC R300 style exhaust fractured all around the inlet end of the silencer. It was only supported at the head and the rear bobbin. That leaves a lot of weight trying to rip the pipe out of the front of the silencer as you drive. Got a new system later from PowerSpeed ... they fitted a front support and bobbin and it carries the system well. Dont need any bolted ears or springs between primaries and collector either. Did get a crack in inlet near front of silencer when driving in the Pyrenees .... then found front exhaust bracket bolt was loose. Fortunately found a stainless welding workshop only 30km from our mountain top chalet ... they stayed open through lunchtime (!) to weld it up, and refused payment ... apart from a donation to their coffee jar.

Member Jonathan Kay Posted March 25, 2020 Member Share Posted March 25, 2020 Thanks, Ian.That's why I asked about the number of brackets. I don't know who has how many, or whether that's affected by the type of silencer. I have a front bracket so I probably overestimate the number that do.And when I look at mine and read about failure at the inlet to the silencer that's where I'd expect the flexing to cause a problem.Jonathan Link to comment Share on other sites More sharing options...
7 wonders of the world Posted March 25, 2020 Share Posted March 25, 2020 My thro the bonnet 4:1 with a 7" x 950mm can only uses the rear bracket as it design for that purposes by Mike Edwards in Wisbech Link to comment Share on other sites More sharing options...
Titanium7 Posted March 25, 2020 Share Posted March 25, 2020 As the Raceco exhaust is so light (around 5.6Kg) it only uses the rear support bracket. Link to comment Share on other sites More sharing options...
GPBox Posted March 26, 2020 Share Posted March 26, 2020 Nowhere near as shinny as Titanium7, but my K-series only uses the rear bracket,....no issues so far.... (cannot figure out how to rotate image !) Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted March 27, 2020 Member Share Posted March 27, 2020 There's a genuine problem with image orientation on the site when using an iPhone, and there's now an explanation in the archives.I rotated that one on my Mac by:Downloading the image.Opening it in Preview, rotating it and saving it.Uploading it to the thread using the shortcut upload.I don't know the details of the equivalent in Windows 10 but I'd put money on there being one.Jonathan Link to comment Share on other sites More sharing options...
elie boone Posted March 27, 2020 Share Posted March 27, 2020 5.6 kg for an exhaust is not light, my all SS can weighs just under 5 kg that's because the outer skin is 0.8mm ! on a cold winters day i can warm my hands on the rear of the can without shedding some skin.
