Title: installing an fmf fatty
Post by: REED on April 02, 2015, 07:25:57 AM

Could you please explain to me the step by step  process of installing a fatty pipe and silencer on an 86R.  I'm having a hard time getting the fit right.  I'm about an inch off of the motor mount, where the pipe bolts up, correct?  And the silencer has different size holes than the stock exhaust.  Where exactly does the silencer bolt up.  

A video would be awesome.

do you have all the exhaust hangers needed to mount the pipe and silencer ? cause that sounds like your problem to me.

Sorry I didn't get pics yesterday. Busy busy and forgot to do it. I just set a reminder on my phone for today.

Looks like I'm only running the front mount by the engine mount and the silencer mount.

If you mount the silencer like that does it melt your rear plastic? My LED pipe mounts like that (no hanger) and it has melted my OEM plastics where it touches.

Jimbo just put a FMF on his sparks pipe. He has it hanging from the OEM hanger.

Yeah the plastics are melted. They were pristine stock ones too. But I bought it that way.
