RB-GTE Posted August 22, 2012 Share Posted August 22, 2012 So I have an autobahn88 1st decate pipe, also a 3" HKS midpipe. Between both of these a restrictor ring will be fitted. I'm going to take the gasket to a machine shop and they will make it based off that, and once its complete a 2" hole drilled through the middle. My question is how thick is it supposed to exactly? so it will bolt up perfect? Of course that will go in the middle between both those pipes, and a gasket on both ends of the restrictor.

listy Posted August 22, 2012 Share Posted August 22, 2012 The restrictor ring is usually arounf the same thickness as a gasket. You could always simply buy one from Whifbitz, around £10 iirc. Quote Link to comment Share on other sites More sharing options...

That's my plan! ^^^ Does it come with the gaskets with the rr? Quote Link to comment Share on other sites More sharing options...
listy Posted August 26, 2012 Share Posted August 26, 2012 I think most just use the RR as a gasket mate. Thats what I did anyway and have had no problems. Quote Link to comment Share on other sites More sharing options...

listy Posted August 27, 2012 Share Posted August 27, 2012 Bit of exhaust paste/fire putty either side of the RR mate. Some dont like doing it way that, but myself and others have had no problems. I get no leaks at all. Quote Link to comment Share on other sites More sharing options...
rallly Posted August 27, 2012 Share Posted August 27, 2012 Cool, thank you. Oh, one more thing. What size rr do I need to be at 1bar? Quote Link to comment Share on other sites More sharing options...
listy Posted August 27, 2012 Share Posted August 27, 2012 Not sure mate, never measured it. Whifbitz do a 1bar RR though as mentioned before. Costs around a tenner. Quote Link to comment Share on other sites More sharing options...
