hello,

i bought on ebay from a very reliable seller the OEM exhaust for my 99 FLHTC twin cam.
I just went back on my ebay and I acutally got confused as the seller says in the description "good for 96-06 touring models", but the the first year of TC was 99...and when i asked the seller if it would have fitted on my 99 FLHTC he said yes... I guess from the curve it is correct but i'm not 100%
could you help understanding from the pics below if it will fit on my twin cam or if i have to contact the seller and return it??

 

I don't know if that will fit but it looks like 2010 or newer exhaust. The big flat section where the 2 pipes come together is where the catalytic converter is. I have seen older bikes with that newer exhaust on but I don't know if it's a direct bolt on or needs some fab work. If you're going to try to put it on, you should de-cat it.

 

Yeah, definitely not OEM exhaust from pre-09. They didn't cross over underneath. That's the 09-16 exhaust. It can be made to work though and looks better IMO.

It will fit your engine, but the O2 sensors (if you have any) are likely different and I think you'll need a bracket underneath to mount it.

 

That is not the head pipe of a early TC
That looks like 2009 up TC

 

I have an '08 system on my 1990 Glide, so Evo and twincam systems will swap, subject to possibly adapting the mounting brackets. A later cross-under system can be made to fit, according to a few members, but requires a little extra effort.
