TG Exhaust

[Davep]

I have a 2011 Triglide with a 103, whats the best exhaust to put on it to cool it down that wont cost a fortune?

 

[RedOregon]

I favor Rinehart. Everyone has their opinion. Important thing is getting rid of the catalytic converter. And by the way, pipes are one of the 'you get what you pay for' items-you don't wanna go cheap. Corrosion and cheap brackets aren't pretty.

Changing the mufflers to cool it down will be minimal at best, Removing the cat, getting a good tune, high flow air cleaner, tank lift, wrapping the head pipe with heat wrap, floorboard extension kit will do the most to cool down the engine along with getting rid of some of the engine heat and improving rider comfort.

Yep, it’s a process, not just pipes.

Talk to the folks at Fuelmoto. They know their stuff and what parts works best together with your setup.

In my case, I have a 2020 Ultra and they recommended a Fuelmoto stainless 2-1-2 header pipe, jackpot mufflers, Fuelmoto air cleaner, Woods WM8-22X-E cam kit, Dynojet tuner with a Fuelmoto tuning map, Screaming Eagle aluminum intake, and a Baker compensator. It makes a lot of torque which is what you want for a trike, runs cool, and has a great lopey deep sound idling while not being loud cruising. Plus, it was considerably cheaper and the parts are high quality.

I've already done the tank lift, exhaust wrap, air cleaner and floorboard extensions

I installed the Fuelmoto stainless headpipe and it’s very well made, I also got from them a Power vision 3 with a target map. The cam will come later.

Cheapest is remove cat from your factory head pipe. Cut the baffles out of your slipons and add thunder torque inserts from DK Customs. Mine is a 2011 and has a really good sound to it.

That’s what I like about Fuelmoto. I started out with a Power Vision PV-2B fuel tuner and air filter first and they sent me a tune. Then later I upgraded the exhaust and they sent me another tune. Then the cam came later and another tune.

I did a set of slip ons first, then saved my pennies(thousands of them) and did the head pipe, air cleaner, cam, tuner and a full dyno tune at one time.

Removing the cat will void the warranty and it isn't necessary. The engine can be tuned very well with the cat in place. I did a stage III on my last M8 and left the cat in for warranty. The bike ran cooler and made gobs of power for 5 years, no worries! The stage III is a great engine! I may do a stage II on my Tri-Glide but I'll leave the cat in and the warranty good!

 

[HDUSA1]

Good point about the warranty if the bike is newer and still covered. The OP’s bike is a 2011 and probably way outside any Extended plan if he had one.

The tuner does reduce the heat the cat puts off, but there is a significant improvement in both heat and the sound (especially in an M8) of the exhaust once it’s removed though.

De-catting a stock pipe works, but it does not flow as well as a header pipe designed without it.

 

[Notgrownup]

I have a aftermarket warranty and it’s covered with the Fuelmoto headpipe

 

[Davep]

I dont have a warranty, but I'm not comfortable removing the cat, I think I might screw something up since I dont really know how to do it, I'll probably save my pennies and go for the Rinhart full system

 

[Oldster]

I was told by a guy that runs a dyno regularly that removing the cat doesn't really make that much difference. I do know that my 114 stage III motor sounded great, ran cool and made more HP than I needed [around 120]. I was told by the dyno guy that removing the cat might make another 5hp and I wouldn't be able to tell the difference other than it would be louder! 12-1 compression and neighbor haters were plenty loud enough!

I changed mine because of heat not really performance.

I think we are saying the same thing, just in a different way.

I rode and heavily modified the motors in my Victory bikes for several years until they quit making them and learned a lot from Lloyd Greer who was a Master engine builder and tuner for both Victory’s and HD’s.

According to him, all engines require a properly designed and tuned exhaust to make the maximum power. Backpressure and the pulse wave in the pipe affect how well the cylinders scavenge.

Removing the cat in most cases actually reduces the power and bottom end torque quite significantly, especially if it is coupled with a large straight through muffler design. It causes reversion in the exhaust which can also cause the popping and backfiring frequently heard. No tuner will ever compensate for a poorly designed exhaust. Attempts can be made using antireversionary cones in the engine exhaust ports, but you lose top end to regain bottom end.

After I bought the Harley I have now, I was all set to put Rineharts on it. The local dealers all push them as they sound great and look nice.

Then I remembered Lloyd’s Words of Wisdom and started researching how to make power in a Harley when I stumbled upon Fuelmoto. My first call to them, I spoke to Bob and he was quite blunt with me when I told him I wanted to put on Rineharts. He said I had a decision to make, do you want Looks and Loud, or do you want power and a reliable bike you can ride anywhere?

I got my back up back at first, but after we talked through it, it made a lot of sense and they really do know their stuff. I’m quite happy with my setup from them and the bike runs cool, has gobs of torque from bottom to top, has a distinct deep lopey idle rumble, and is quiet at cruising speeds for long distance rides.

The head pipe I went with was the Fullsac sport pipe which appears to be no longer available. This head pipe had the factory oval converter tube removed and two separate pipes were welded back in place, along with the S&S 465 cam and tune my 107 makes 91 hp from stock 76 and torque went from 90 to 106. But it makes 102 ft lbs at 2300 rpm, which is perfect for my riding style. Especially when pulling my trailer.

Khromewerks makes a non cat head pipe called the hideaway that appears stock , works with stock heat shields and bolts right up in place of factory head pipe. To help beat the heat I did one on my 21 TriGlide and added the DEI heat shield insulation under the heat shields . Big difference in heat and sound. Both available through local Drag dealer
