The mounting holes on that mount make me think it mounts to the transmission.

 

 

Very Nice... I think I will copy that!!!
Thank you Much!!!

 

Works great so far! I’ve heard a lot of complaints about the stock hardware. But all good reviews for this one

 

1996 FXDL with Thunderheader / Mikuni 42, some S&S heads (modified), pushrods , lifters.
Comp Cams EVL-5005 cam. Some transmission work with Baker parts. Not quite 10:1 static comp.
If I keep her 80-85 mph , I'll get the lesser gas mileage.
Keep her around 70-75, I get closer to 40 mpg. And the old girl gets down the road , real well.

Ride Safe,
Harold.

 

Switched to a Thunderheader a few years back, because The MoCo had obsoleted the right side exhaust wye. I needed to replace the SuperTrapp slipons I had anyway.



I needed to install some spacers on the floor boards as they hit the front pipe. Kuryakyn sells a kit. The ThunderHeader is a bit louder than the SuperTrapp slipons with 16 discs. It definitely has a distinctive tone. But I don't find it too obnoxious. I get high 30 mpg around town, and 40+ on the highway doing 70-75mph. 80", street ported heads, EV27 cam, Dyna 2000 module, and Arlen Ness air cleaner setup.

 

I have a 98 Dyna with 80 inch evo, thunder header, S&S super e carb. I get about 150 miles to a tank roughly 3 gallons, so right at 50mpg.

 

Curve looks good... I'm sure it pulls nicely..

 

I have one on my 86 heritage, mileage know idea. I have a s&s 96" with 10.5 compression and s&s E carb. Good power and great sound.

 

Really enjoying all these photos. Work in progress but the Thunderheader is the first thing I put on.
