jono Posted May 4, 2014 Share Posted May 4, 2014 Sheesus, how hard was that ?? Only through discussions about the web to find these Y pipes are double walled, pipe inside pipe (so, I was not getting bigger pipes fitting L Series Y pipe on EA81). Inside pipes can burn out or rot just below flange at head, pipe inside rattles like buggery on acceleartion, some cruise, some backing off, sometimes goes dead quiet. Went dead quiet after I fitted EA82M and then it came back.This idea came to me. Tried one screw up top first on RHS, then LHS, then lower RHS. 5 cents a self drilling gal screw with 8mm hex head. Tookl mere minutes to do first and go for a drive with more screws in pocket, drill driver beside me.Jono's 20c fix 1 Quote Link to comment Share on other sites More sharing options...
l75eya Posted May 4, 2014 Share Posted May 4, 2014 Nice! Hope they hold. Lots of temperature change there. Quote Link to comment Share on other sites More sharing options...

GlenSz Posted May 4, 2014 Share Posted May 4, 2014 i got the same problem, i'll try this...it probably won't hold in the weather, @175eya, haha, how you doin? Quote Link to comment Share on other sites More sharing options...
MR_Loyale Posted May 4, 2014 Share Posted May 4, 2014 That is a clever fix. I think i got that rattling too. Quote Link to comment Share on other sites More sharing options...
jono Posted May 4, 2014 Author Share Posted May 4, 2014 I sort of thought it best to screw them in while pipe was hot, hoping the minute expansion while hot does not expand any more or someone behind will cop a puncture I forgot to say that as the screw popped through outer pipe, I could then feel screw drilling into second pipe inside so the thread should be in two pipes. Going to dump a blob of silicone to hold the heads to the pipes It is like a different car right through the rev range. Thought I was going to have to punk up my pipes a lot more than that before I found the spot I am happy with the cheap'n'cheerful success 1 Quote Link to comment Share on other sites More sharing options...
l75eya Posted May 5, 2014 Share Posted May 5, 2014 If it loosens maybe try carriage bolts through the whole thing with a nut on the other side. Quote Link to comment Share on other sites More sharing options...
jono Posted May 6, 2014 Author Share Posted May 6, 2014 (edited) ah, ah, the idea of the screws is to draw the inner pipe towards the outr pipe to add some stress or tension to it to keep that rattle at bay. A straight through and across style bolt - besides making it look like Frankenstein would not do the intended job. no one has asked to see the other side of the rims yet ??

turbosubarubrat Posted May 7, 2014 Share Posted May 7, 2014 Tack the screws with a welder so you don't have to worry about them coming out. Quote Link to comment Share on other sites More sharing options...
jono Posted May 8, 2014 Author Share Posted May 8, 2014 Iiiittttt''''sss bbbbaaaccckkkkk !!!!!!!! More screws me thinks Quote Link to comment Share on other sites More sharing options...
jono Posted May 23, 2014 Author Share Posted May 23, 2014 it's not back ...screws were starting to loosen off their hold tension on inner pipe. A retension and some silicon as a fastening device and she's apples again Quote Link to comment Share on other sites More sharing options...
