High Performance Exhaust System For The FT500
thumperdh:
I just got mine in today. Looks great, mine was one of the glossy versions. It's dark and raining down here in Florida and I have to work or travel every day in the foreseeable future so i'm not sure when I'll have it mounted.

I plan on heat cycling mine at first, to make sure that the ceramic finish is cured. I'm going to start the bike & warm the header pipe just slightly, then shut it down, let it cool & repeat. Each time I'm going to let the pipe get a bit hotter than the last & then let it cool to the touch & repeat.
I had a set of headers ceramic coated & this heating/cooling cycle was recommended/required to maintain the warranty.
Good luck

Okay! Managed to sneak out of work a little early tonight to put the exhaust on.
Here's what you need to know when you put the head pipe on.
The 12mm bolt that holds the regular head pipe on right below the RH foot peg is not needed to install the Thumperstuff Head pipe, instead of mounting with the 12mm bolt, the head pipe bolts up to the 17mm bolt just above it. If you leave the 12mm bolt in place, it will not fit.
The O.D. of the head pipe where you will bolt your muffler to is almost exactly 1 3/4" so if you have a supertrapp exhaust like mine with a 1 3/4" O.D. you will have to bend it a bit to fit.
The fit isn't perfect, you will have to mock it up and bend it just a hair to get everything to sit right. Don't worry, this isn't anything you can't do by hand.

I finally made the time to install my new Header Pipe today. It was all pretty straight forward. Carefully remove the old exhaust system & hang on to the bolt (12mm head I think) that you remove near the lower motor mount. You won't be needing that bolt for the new exhaust but you should keep it with old exhaust system. Next you need to remove the lower rear most motor mount nut & washer. The new pipe hangs from the motor mount instead of the place where the old pipe connected. The only part of the exhaust swap that gave me any problem was trying to keep the new exhaust gaskets in place & slipping the collars in while holding everything in position. After a couple of failed attempts, I used a thin strip of masking tape to hold the gaskets in place. That allowed me to get it all together & then I burnt some of the tape during start up. A bit primitive, but it worked.
I have a Cobra slip on muffler from my stock exhaust. The Cobra exhaust inlet is sized for the OEM pipe & is a larger I.D. than what will fit the ThumperStuff Header outlet. Fortunately I had one of those universal 3-piece exhaust reducer sets laying around & one fit the gap perfectly. This allowed everything to be snugged up evenly & fit real well.
When you hold the OEM exhaust downtubes next to the ThumperStuff Header, the benefits & advantages of the ThumperStuff Pipe are readily apparent. Nice long, smooth down tubes that merge together well at the collector, vs. the OEM pipes design where the exhaust pulses look as though they collide together. The ThumperStuff Header is a very nice Pipe! 8)
Anybody have anything else to add, or have any questions?
Thanks

Here are a few more pictures of the Header mounted on the bike. Look how closely it follows the engine. It fits high & tight like it should.
