elclem1 Posted January 7, 2021 Report Share Posted January 7, 2021 Good evening all, Has anyone re imported a TR6 from the US and removed the emission system? I have a friend here who has a '76 TR6 and its still running on the emission system. Most of the stuff is about removal of pipe and blanking off any holes that are left i think. However i note that there are pipes that come from the exhaust manifold in to what appears to be a 3/16" pipe manifold and go into the emission system does this need to be removed or manifold replaced ? I would be grateful for any hints advice on this one please. cheers Clem Quote Link to post Share on other sites

elclem1 Posted January 8, 2021 Author Report Share Posted January 8, 2021 Yes I get that, looks like I need to change the exhaust manifold as I have one here. Thanks. Quote Link to post Share on other sites
