Did a search and have found varied opinions. I've installed and reinstalled my THeader using new SE gaskets three times now and cannot get a proper seal on the rear port. Doesn't seem like the THeader goes far enough into the port to press against the gasket.

At this point I'm not sure whether to try the stock gaskets, or double up on the SE ones. Seems like the exhaust should push further into the ports, but the bolt for the mid control is rubbing the bottom pipe and I can't see a way around that.

Anyone use the stock gasket for a THeader? '02 FXD. I'm only concerned about the tapered style protruding into the port. And yes, I've tighten the nuts evenly and torqued to spec each time, just will not seal

 

Does the T.H. have tapered or square flanges on the head pipes? That will determine which gaskets you should be running. Don't be afraid to torque the flange nuts beyond the torque spec, it seems on most systems to get a good tight seal we have to go beyond the spec to get them sealed. After you put some miles on the bike, check the nuts as they will most likely be loose as the gasket crushes and the head pipes really take a seat.

 

It's rounded off on the edges, another reason I figured I'd try the stock gaskets. After getting pissed last night I did crank the rear ones down well passed what my brain said was a good idea. No change after checking with a lighter

 

Well, went ahead with the OEM gaskets. Exhaust would not set into the port far enough to allow the nut to thread onto the lower stud on the front jug. Managed to get it to grab, but then found it was stripped.

So now I'm stuck trying to weld a nut onto there to remove it, if that doesn't work I may as well pull the motor and start ordering parts for my winter build
