Pipe sold..........

Conan · #22 27th February 2021

As it turns out I picked up the pipe. If madnss has anything for sale don't hesitate- great guy!

I'm mounting to my '02 1200C with a new 1275 and '04 heads. Tried to bolt it on tonight and the stock for '02 exhaust flanges don't seem to fit the '04 heads. Anyone know if they got smaller for '04? Part numbers are the same on the parts fiche. Wouldn't hijack the thread but it is related to this pipe.

Thanks, Kyle

You may have to trim the bottom fin for the flanges to clear.

Conan · #24 27th February 2021

I did get the flanges on, just took a little doing. Hopefully I'll finish the install once the bike is back on the ground in a couple days. I'll shoot a quick video once it's running. Kyle

Quick update for anyone that wants to fit this pipe to a solid mount, it's very doable and very easy! With a couple hints from madnss I used my stock rear mount from the frame back to the Riot muffler and welded the Riot mount (at the muffler end) to the factory piece. If the pics work, see below.

Mount as a whole:

Sure the welds are ugly but I haven't welded in 15 years, and this was the first go with the Harbor Freight Easy Flux 125 picked up to do this job. Kyle
(Oh, it sounds great, btw! Very throaty and aggressive.)

Awesome stuff Kyle! At least guys n gals now know what it takes to fit this pipe onto 03 and older with mids and forwards. Pipe is Beautiful in person on the bike imho.

It looks great to me too! And not as loud as I'd thought, but coming off of Straight Shots I don't have a good baseline.
It fits forwards very well with zero interference or even being close to the pipes. Like it was designed to fit! It does stick out more than the Straight Shots though and I'll have to get used to that. I noticed it most when backing up but is certainly not a big deal. Kyle

That Magnaflow motorcycle exhaust might be too loud for my taste.

FYI the vids I posted, the riot is strapped on a 120hp 1250. That does make a huge difference in the sound and noise level compared to a 50-75hp bike imho.

My phone decibel meter at 3' from the tailpipe read 90dB at idle, ~107dB at 2k, and 108-110dB at 3400. I haven't had the motor above 3500 yet (break-in period...still) and that was on the road. At idle it's comparable or a little quieter than the Straight Shots it replaced but while riding it definitely seems more aggressive and louder. Again it's hard to tell without taking it even onto the cams. This is on a ~90 HP build. Kyle
